(LEACH)2: Combining LEACH with Linearly Enhanced Approach for Cluster Handling in WSNs

Wireless Sensor Networks (WSNs) are expected to have wide applicability in the near future. In this paper, we propose (LEACH)²: Linearly Enhanced Approach for cluster handling improving the conventional protocol LEACH (Low Energy Adaptive Clustering Hierarchy) in WSNs. We divide the network area into four regions and study the network performance in the presence of one, two and three sinks. Simulation results show that our technique with three sinks performs better than other conventional routing techniques. (LEACH)² offers increased stability period, network lifetime and throughput than LEACH.
