The Wireless Sensor Network (WSN) is an emerging field of wireless network comprising of few to many autonomous tiny sensors nodes, with limited processing, limited memory, limited battery power, limited bandwidth and limited wireless transmission capabilities. The life time of the sensor node depends upon the battery power. WSN are commonly used to monitor environmental conditions like temperature, sound and pressure etc. WSN is an application of MANET. Wireless sensor node collects data and sends back to the sink or Base Station (BS). Data transmission is normally multi-hop among sensor nodes that enable these nodes to transmit data from hop to hop towards the sink or BS. Wireless sensor network requires robust and energy efficient communication protocols to minimize the energy consumption as much as possible. Main penalty area of researchers is to design the energy efficient routing protocol. Routing protocols should be energy efficient, scalable and prolong the network lifetime...
Wireless Sensor Networks (WSNs) are required to provide energy efficiency and different level of Quality of Service (QoS) based on the type of applications.

A survey on various energy-efficient routing protocols in WSN
The applications and the role of Wireless Sensor Networks (WSNs) in real-world encourage researchers to elaborate and explore more information about it. As we know a WSN consist of thousands of sensor nodes (static or mobile) which gather information from a specific region and then transmit its base station (static or mobile) with some mechanism. There are various protocols that are proposed to govern this communication in an effective way. But the challenges such as energy consumption, mobile sink scheduling, and data aggregation still need to improve. So that the lifetime of WSN can be extended. This paper cover and present a survey on some protocols and related research works for WSN challenges that improve the performance of the network.
SET: Smart Energy Management and Throughput Maximization: A New Routing Protocol for WSNs
IGI-Global-Security Management in Mobile Cloud Computing, 2017
Energy efficiency and throughput are critical factors in the design routing protocols of WSNs. Many routing protocols based on clustering algorithm have been proposed. Current clustering algorithms often use cluster head selection and cluster formation to reduce energy consumption and maximize throughput in WSNs. In this chapter, the authors present a new routing protocol based on smart energy management and throughput maximization for clustered WSNs. The main objective of this protocol is to solve the constraint of closest sensors to the base station which consume relatively more energy in sensed information traffics, and also decrease workload on CHs. This approach divides network field into free area which contains the closest sensors to the base station that communicate directly with, and clustered area which contains the sensors that transmit data to the base station through cluster head. So due to the sensors that communicate directly to the base station, the load on cluster heads is decreased. Thus, the cluster heads consume less energy causing the increase of network lifetime.

REVIEW OF QUALITY OF SERVICE IN ROUTING PROTOCOLS FOR WIRELESS SENSOR NETWORKS
Rapid innovative improvements in wireless communication technology have revolutionized wireless sensor networks (WSNs). A WSN is comprised of self-ruling sensors that are distributed spatially to monitor physical or environmental conditions, such as temperature, sound, vibration, pressure, motion, or pollutants, and to pass this information through the network to a main area. Sensor nodes in wireless sensor networks experience the ill effects of resource constraints, such as energy deficits, buffers, and bandwidth issues. The expanding demand for real-time services in WSN applications means that interest in quality of service (QoS)-based routing has risen. Offering consistent QoS in sensor networks creates considerable challenges. In real time applications, it is important to deliver data as soon as it is sensed. If the network has multiple real and non-real-time applications, its ability to manage them will be challenging due to different requirements. In this study, we investigate QoS-based routing protocols for WSNs. Metrics of analysis are end-to-end delay, congestion, energy efficiency, and reliability. The aim of the study is to identify the limitations of relevant papers and show research direction in routing. This will not only help new comers to the field of WSN but also will ease the tasks of WSN researchers in developing appropriate routing solutions for WSNs.
QoS-Aware and Heterogeneously Clustered Routing Protocol for Wireless Sensor Networks
IEEE Access, 2017
Wireless sensor networks (WSNs) have gained much attention in today's research domain for supporting a wide variety of applications including the multimedia applications. Multimedia applications that are regarded as the quality-of-service (QoS)-aware, delay sensitive, and bandwidth hungry applications require enough energy and communication resources. WSNs being the energy-scarce network have now been designed in such a way that they can support these delay-sensitive and time-critical applications. In this paper, we propose an energy-efficient routing protocol for heterogeneous WSNs to support the delay sensitive, bandwidth hungry, time-critical, and QoS-aware applications. The proposed QoS-aware and heterogeneously clustered routing (QHCR) protocol not only conserves the energy in the network, but also provides the dedicated paths for the real-time and delay sensitive applications. The inclusion of different energy-levels for the heterogeneous WSNs also provides the stability in the networks while minimizing the delay for the delay-sensitive applications. Extensive simulations have been performed to validate the effectiveness of our proposed scheme. Our proposed routing scheme outperforms other state-of-the-art schemes in terms of the delay performances. INDEX TERMS Wireless sensor networks, energy efficiency, quality of service, real-time traffic. I. INTRODUCTION Wireless sensor networks (WSNs) have gained much attention in the modern world because of their sensing capability. The micro-electro-mechanical system [1], [2] provides tiny low-power sensor nodes. The sensor nodes can sense, process, and then forward the data to other nodes for further investigation. The architecture of a tiny sensing node is shown in Fig. 1. Tiny sensing nodes can be applied to various fields to sense the required data. WSNs have found their way to many fields, such as health, industry, military, civil, and transportation systems [3]-[6]. These sensing nodes have limited resources. Scarce resources with limited battery life demand from designers of tiny sensing nodes the design of energyefficient platforms, operating systems, radio modules, and communication protocols for sensing nodes [7], [8]. WSNs have been extensively employed to sense the diverse kind of data. The various challenging applications of the WSNs as has been discussed in [9] and [10], demand from sensor nodes to support the not only the energy-efficient communications paradigms but also the delay sensitive support.

This is just unnecessary wastage of nodes energy. But the routing protocol like DSR (Dynamic Source Routing) protocol collect their routing information's through such overhearing, they would suffer if they are used in combination with 802.11 PSM. Wireless sensor networks are made up of number of tiny mobile nodes which are having the capability of computation, sensing and wireless network communication. The energy efficiency of every node is one of the important issues in such kind's networks under considerations. Thus for this networks, sensor nodes life time is basically depends on use of routing protocols for routing operations in WSN. There are various routing protocols are proposed by the different researchers which are considered as efficient on the basis of performance of network lifetime and energy scavenging. There are different methods which are introduced for the WSN routing protocols such as flat routing protocols, clustering routing protocols, hierarchical routing protocols etc. In this project, our studies basically are focusing on the investigation and analysis of hierarchical routing protocol (H-Pro) and flat routing protocol. We carried out the detailed study of (H-Pro) protocol, its architecture, and design considerations. We are performing the investigation over the performance analysis two kinds of routing protocol of sensor networks such as (H-Pro) (hierarchical routing protocol), PEGASIS (flat routing protocol). Here the performance of this new protocol is evaluated on the basis of throughput and energy consumption.
