The occurrence of‘sensing holes’not only hinders seamless data col-lection but also leads to misinterpretation of information in certain areas under extensive data *** order to overcome this,various sensor relocation stra-tegies have been proposed,but the existing relocation strategies revealed pro-blems such as the ping-pong,shaded area,network disconnection,*** paper conducted research on relocation protocols in a distributed environment that is very suitable for real-world situations and efficiently recovering the problem of sensing ***,a simulation was performed on the distribution of the shaded area for data collection,which is a problem with the existing representative relo-cation *** that,a data collection capability was newly added to the relay node,which had been in charge of only communication between cluster zones so far,and with this additional functionality,the performance of the revised sensor relocation algorithm was dramatically improved to overcome the existing *** addition,the performance and validity of the proposed algorithm were verified through various simulations.

Efficient Algorithm for Prolonging Network Lifetime of Wireless Sensor Networks

引用

Tsinghua Science and Technology 2011年第6期16卷 561-568页

作者： Md Nafees Rahman M A Matin Department of Electrical Engineering and Computer Science North South University

One of the fundamental design challenges in designing a Wireless Sensor Network （WSN） is to maximize the network lifetime, as each sensor node of the network is equipped with a limited power battery. To overcome this challenge, different methods were developed in the last few years using such techniques as network protocols, data fusion algorithms using low power, energy efficient routing, and locating optimal sink position. This paper focuses on finding the optimal sink position. relay nodes are introduced in conjunction with the sensor nodes to mitigate network geometric deficiencies since in most other approaches the sensor nodes close to the sink become heavily involved in data forwarding and, thus, their batteries are quickly depleted. A Particle Swarm Optimization （PSO） based algorithm is used to locate the optimal sink position with respect to those relay nodes to make the network more energy efficient. The relay nodes communicate with the sink instead of the sensor nodes. Tests show that this approach can save at least 40% of the energy and prolong the network lifetime.
