Energy Efficient Clustered Routing Protocols of LEACH
Journal Title: International Journal for Research in Applied Science and Engineering Technology (IJRASET) - Year 2015, Vol 3, Issue 5
Abstract
Sensor node has a limited amount of battery in sensor network. To prolong the overall lifetime of the network, development of energy efficient routing protocol is a major issue in Wireless Sensor Network. Clustering protocols are one of the approaches to serve this purpose. LEACH is a well-known routing protocol based on clustering, but it has several problems like short network lifetime. Due to inefficient energy consumption several variants have been proposed to overcome these problems in LEACH. Here analysis of variants of LEACH namely LEACH-C, Multi-hop LEACH, Energy LEACH is done. LEACH-C can be chosen when centralized and deterministic approach covering entire network is expected still bringing in increased network lifetime and desired number of clusters. When network’s diameter is increased beyond a certain level, distance between CH and BS is increased enormously Multi-hop LEACH is chosen. Energy-LEACH tries to achieve efficient energy utilization. Simulation results show that our protocol outperforms the LEACH in terms of the parameters under consideration.
