Energy Efficient Scheme for Wireless Sensor Networks

Recent advances in wireless sensor networks have commanded many new protocols specifically designed for sensor networks where energy awareness is an important concern. This routing protocols might differ from depending on the application and the network architecture. To extend the lifetime of Wireless sensor network (WSN), an energy efficient scheme can be designed and developed via an algorithm to provide reasonable energy consumption and network for WSN. To maintain high scalability and better data aggregation, sensor nodes are often grouped into disjoint, non-overlapping subsets called clusters. Clusters create hierarchical WSNs which incorporate efficient utilization of limited res ources of sensor nodes to reduce energy consumption, thus extend the lifetime of WSN. The objective of this paper is to present a state of the art survey and classification of energy efficient schemes for WSNs. Keywords: Wireless Sensor Network, clustering, energy efficient clustering, network lifetime, energy efficient algorithms, energy efficient routing, and sensor networks.

An Energy Efficient Routing Protocol in Wireless Sensor Networks

2009 International Conference on Computational Science and Engineering, 2009

Wireless sensor networks are used in a wide variety of applications in our day to day life, these networks consists of small electronic devices called node or motes. These nodes will be deployed in large numbers, which are self powered, gather information or detect the required events and communicate it to the base station in a wireless mode. Sensor networks provide more number of opportunities, but at the same time pose challenge like scarcity of energy, as they have non-rechargeable batteries. As the nodes are deployed in the random fashion, due to high density of nodes, more than one node may fall in a very close proximity or in other words, two or more nodes which are very closely situated will be sensing a similar data. In this paper, we present an energy efficient routing protocol based on the closeness factor. In this approach, as soon as the deployment of the nodes is made, the base station will be grouping the set of nodes deployed in to two disjoint sets based on the closeness factor of the nodes and keep one set of nodes inactive till the other node's energy gets depleted. Simulation results prove that lifetime of the entire network can be improved by the proposed method.

Energy Efficient Routing in Wireless Sensor Network

2012

Wireless sensor networks (WSN) have achieved tremendous research interest in recent times because of their multidimensional applications in both civilian and military purposes. But, providing flexible service using wireless sensor network is challenging because they usually contain a large number of resource constraint sensing nodes with small memory, lower processing capability and extremely limited battery life. In this paper, we present an extensive survey on existing routing schemes and propose an effective approach for data communication for such resource constrained sensor network. The main contribution of our paper is, it proposes an enhanced routing scheme which is power efficient and also robust to node failures. It is also a mentionable feature of our research that, our proposed schemes takes the resource constraints of individual sensor nodes into concern and provides a communication scheme which focuses on the balanced work load distribution in sensor network. Our proposed scheme introduces cluster coordinators and focuses on adopting computationally simple approach and consequently minimizes the power consumption for routing phases as well as data transmission steps.

Low-Energy Aware Routing Mechanism for Wireless Sensor Networks

IFERP, 2018

Wireless Sensor Networks are a collection of several hundred nodes that together sense some physical quantity and transmits the same to a central node, known as the base station. These sensors are miniature electronic circuits or devices that are capable of sensing data and establishing connection in between themselves. Due to the frequent transmission and reception of data in these sensor nodes, the overhead of these nodes are sinusoidal. Hence, increasing the network lifetime without disrupting the topology and the functionalities of the system is one of the main challenges in WSN. Moreover, due to the existence of cyclic events such as election of Cluster Heads (CH), energy is wasted. In this paper, a methodology is proposed to eliminate the cyclic execution of such events in order to conserve energy for more important functionalities. The proposed methodology yields an energy aware routing protocol accounting the residual energy of every participant node in a cluster and forecasts the next cluster head based on the energy parameters to select the most suitable CH. The proposed methodology eradicates the simultaneous selection process of new cluster heads after each cycle, and in terms, saves substantial amount of energy that is later on used by the participant nodes to transmit and receive data. Performance analysis of the system is carried out with programming tools and the results are shown.

A Novel Routing Protocol for Low-Energy Wireless Sensor Networks

Journal of Sensors

The battery power limits the energy consumption of wireless sensor networks (WSN). As a result, its network performance suffered significantly. Therefore, this paper proposes an opportunistic energy-efficient routing protocol (OEERP) algorithm for reducing network energy consumption. It provides accurate target location detection, energy efficiency, and network lifespan extension. It is intended to schedule idle nodes into a sleep state, thereby optimising network energy consumption. Sleep is dynamically adjusted based on the network’s residual energy (RE) and flow rate (FR). It saves energy for a longer period. The sleep nodes are triggered to wake up after a certain time interval. The simulation results show that the proposed OEERP algorithm outperforms existing state-of-the-art algorithms in terms of accuracy, energy efficiency, and network lifetime extension.

Energy-Efficient Routing Schemes for Wireless Sensor Networks

Microsensors operate under severe energy constraints. Depending on the application, sensors can be thrown randomly in an area of interest ("sprinkled in a field") or, in some cases, can be manually placed in specific positions. The sensor network is typically ad hoc, formed by local self-configuration. Data-centric routing is a new use- ful paradigm for energy-constrained sensor networks. The data

Energy aware routing for wireless sensor networks

… 2005. Proceedings of the IEEE Symposium …, 2005

Self organizing, wireless sensors networks are an emergent and challenging technology that is attracting large attention in the sensing and monitoring community. Impressive progress has been done in recent years even if we need to assume that an optimal protocol for every kind of sensor network applications cannot exist. The energy constraint sensor nodes in sensors networks operate on limited batteries, so it is a very important issue to use energy efficiently and reduce power consumption. Many routing protocols have been proposed among these protocols, the adaptive routing protocols are very attractive because they have low routing overhead. As a result, the routes tend to have the shortest hop count and contain weak links, which usually provide low performance and are susceptible to breaks. In this paper we introduce an adaptive routing protocol called energy aware routing that is intended to provide a reliable transmission environment with low energy consumption. This protocol efficiently utilizes the energy availability and the received signal strength of the nodes to identify the best possible route to the destination. Simulation results show that the energy aware routing scheme achieves much higher performance than the classical routing protocols, even in the presence of high node density and overcomes simultaneous packet forwarding.

2012

179 Abstract— Wireless sensor networks have recently received tremendous attention from both academia and industry because of their promise of numerous potential applications in both civilian and military areas. A wireless sensor network consists of a large number of small sensor nodes with sensing, data processing, and communication capabilities, which are deployed in a region of interest and collaborate to accomplish a common task, a sensor network has many unique characteristics, such as denser node deployment, higher unreliability of sensor nodes, asymmetric data transmission, and severe power, computation, and memory constraints, which present many new challenges for the development and eventual application of wireless sensor networks. In particular, sensor nodes are usually battery-powered and should operate without attendance for a relatively long period of time. In most cases, it is very difficult and even impossible to change or recharge batteries for these sensor nodes. Th...

A Study On Energy Efficient Routing Protocols In Wireless Sensor Networks

International Journal of Distributed and Parallel systems, 2012

A wireless sensor network (WSN) consists of low cost, low power, small in size and multi functional sensor nodes. Routing protocols in WSNs emphasize on data dissemination, limited battery power and bandwidth constraints in order to facilitate efficient working of the network, thereby increasing the lifetime of the network. Routing protocols in WSNs are also application specific which has led to the development of a variety of protocols. Based on the underlying network structure, routing techniques can be classified into three categories: data-centric, hierarchical and location based routing. WSN has a design trade-off between energy and communication overhead which forms the nerve center of the routing techniques. In this paper we present a survey of state-of-the-art routing techniques in WSNs under all the three categories. We epitomize these routing techniques and bring out the advantages and disadvantages followed by their application domain. The paper concludes with issues open for research.

A Survey on Energy Efficient Routing Techniques in Wireless Sensor Networks

Sensor networks have become an emerging new tool for habitat monitoring in nature preserves, it monitors and grouping events in unhealthy environments, it does the work of buildings surveillance, monitoring the enemy activities in a fight field environment. Sensor nodes have less storage capacity, limited energy resources and they are energy constrain. To designing the efficient routing protocol is difficult in order to prolong the lifetime of the sensor nodes. Sensor networks are mainly designed for controlling and reporting events though sensor nodes are application dependent, designing a single routing protocol cannot be effective for sensor networks for all applications. In this paper, we first analyze the requirements, closeness and distinguish between sensors networks and MANETs (Mobile Ad hoc Networks). Cluster formation reduces the nodes involved in transmission &conserves the energy. The cluster based protocols are energy efficient & prolong the network lifetime when compared to other protocols.
