MLCP: Multi level Clustering Protocol in Wireless Sensor Network

Abstract

The basic goals of wireless sensor network are to enhance the lifetime of the network and also to use the energy of the network nodes efficiently. There are so many traditional approaches or techniques available in wireless sensor network(WSN) to achieve the above goals. But, they are not so efficient and reliable in terms of utilization of energy of the nodes in the network. Thus, Clustering is one of the key techniques to achieve the above goals in wireless sensor network with less energy consumption. It can also increase network scalability. Sensor nodes are typically considered to be homogeneous in nature since the researches in the field of wireless sensor networks have been evolved but in reality, homogeneous sensor networks hardly exist. Thus, we require a clustering technique which will work in heterogeneous environment which are more closely associated with real life scenarios. In this thesis, investigations have been made to design a heterogeneous aware clustering technique named“Multi level clustering protocol” (MLCP) in wireless sensor network in order to ensure the protocol to closely work with the real life situations. The main objective of the Multi level clustering protocol(MLCP) is to extend the stable region of wireless sensor nodes, which finally increases the life time of the network with efficient energy usage. The protocol classified the nodes into different types in term of their energy levels. Finally, the simulation result shows that MLCP gives better performance than the existing system, Low Energy Adaptive Clustering Hierarchy (LEACH) and Distributed Election Clustering (DEC) protocol. There are two variants of Multi level Clustering protocol(MLCP). They are Multi level Election Clustering Protocol((MLECP)) and Multi level Randomized Clustering Protocol(MLRCP).
