Performance analysis of approaches for coverage issues in WSN

摘要

Wireless Sensor Networks is an emerging technology in the field of communication. Wireless sensor nodes provide real observed data from the different environmental conditions and provide data for monitoring and controlling the systems. WSNs are suitable for various applications such as intelligent surveillances, border security and disaster management by gathering remote data about surroundings either periodically or on demand. The major considerations of WSN are resource scarcity in terms of bandwidth and energy, coverage and route optimality. In WSNs distinct Localization Approaches, Clustering Techniques, Routing protocols are used to minimize the energy requirement, improve the communication effectiveness, and maximize the throughput and efficiency of the network. The significant improvement in the network lifetime is also achieved by using various approaches such as swarm intelligence and bio inspired techniques. In this paper we have discussed the various clustering techniques proposed by the researchers and provide a comparative analysis of them. To develop a novel method to solve the multi objective problem of energy conservation, node localization, optimal coverage and best route identification is our future work.
