The field of Wireless Sensor Networks (WSNs) is experiencing a resurgence of interest and a continuous evolution in the scientific and industrial community. The use of this particular type of ad hoc network is becoming increasingly important in many contexts, regardless of geographical position and so, according to a set of possible application. WSNs offer interesting low cost and easily deployable solutions to perform a remote real time monitoring, target tracking and recognition of physical phenomenon. The uses of these sensors organized into a network continue to reveal a set of research questions according to particularities target applications. Despite difficulties introduced by sensor resources constraints, research contributions in this field are growing day by day. In this paper, we present a comprehensive review of most recent literature of WSNs and outline open research issues in this field.
Research Challenges in Wireless Sensor Network: A State of the Play
A wireless sensor network (WSN) has important applications such as remote environmental monitoring and target tracking. This has been enabled by the availability, particularly in recent years, of sensors that are smaller, cheaper, and intelligent. These sensors are equipped with wireless interfaces with which they can communicate with one another to form a network. The design of a WSN depends significantly on the application, and it must consider factors such as the environment, the application's design objectives, cost, hardware, and system constraints. The goal of survey is to present a comprehensive review of the recent literature in wireless sensor network. This paper reviews the major development and new research challenges in this area.
Future Trends in Wireless Sensor Networks
2009
Wireless sensor networks (WSNs)[1] have attracted tremendous attention of the research community in recent years. A vast amount of research work has been conducted to solve the practical and theoretical issues that are still open, which has resulted in a surge of civil and military applications over the last few years. As of today, most deployed WSNs measure scalar physical phenomena like temperature, pressure, humidity, or location of objects.
Sensor networks consist of a set of sensor nodes, each equipped with one or more sensors, communication subsystems, storage and processing resources, and in some cases actuators. The sensors in a node observe phenomena such as thermal, optic, acoustic, seismic, and acceleration events, while the processing and other components analyze the raw data and formulate answers to specific user requests. Recent advances in technology have paved the way for the design and implementation of new generations of sensor network nodes, packaged in very small and inexpensive form factors with sophisticated computation and wireless communication abilities. Although still at infancy, these new classes of sensor networks, generally referred to as wireless sensor networks (WSN), show great promise and potential with applications ranging in areas that have already been addressed, to domains never before imagined. In this article we provide an overview of this new and exciting field and a brief discussion on the factors pushing the recent flurry of sensor network related research and commercial undertakings. We also provide overview discussions on architectural design characteristics of such networks including physical components, software layers, and higher level services. At each step, we highlight special characteristics of WSNs and discuss why existing approaches and results from wireless communication networks are not necessarily suitable in WSN domains. We conclude by briefly summarizing the state of the art and the future research directions.
Applications using Wireless Sensor Networks: A survey
Wireless Sensor Networks (WSNs) received enormous attention in recent years due to its phenomenal ability of implementation in various fields. WSNs consist of a large number of small sensor nodes. These nodes are very cheap in terms of cost. In military operations, there is always a threat of being attacked by enemies. So, the use of these cheap sensor nodes will help to reduce the loss. In this paper, we analyze the existing literature of using WSNs for military applications. We will discuss the available scenarios of using sensor nodes in the military uses. We aim to present a better deployment of sensor nodes for military purposes with the help of existing research work. We will try to identify different areas in which we can reduce the damage in case of militant's attack or enemy's outbreak using an intelligent deployment of nodes.
Wireless Sensor Network: Issues & Challenges
International Journal of Mathematical Archive, 2011
Wireless sensor networks (WSNs) are a new and emerging type of sensor networks that contain sensor nodes equipped with a radio transceiver, other wireless communications devices like a small microcontroller and an energy source, usually a battery. Wireless sensor network is a wireless ad-hoc network that consists of spatially distributed devices that use sensors to monitor physical or environmental conditions. WSNs merge a wide range of information technology that spans computer hardware, systems software, networking and programming methodologies. WSNs make it possible to perceive what takes place in the physical world in ways not previously possible. In addition to offering the potential to advance many scientific pursuits, they also provide a vehicle for enhancing larger forms of productivity, such as manufacturing, agriculture, construction, and transportation.

Following a top-down approach, we give an overview of several new applications and then review the literature on various aspects of WSNs. We classify the problems into three different categories: (1) internal platform and underlying operating system, (2) communication protocol stack, and (3) network services, provisioning, and deployment. We review the major development in these three categories and outline new challenges.
