Abstract
Hierarchical routing having cluster based topology is a very propitious approach for improving throughput. Wireless sensor networks (WSNs) are distributed networks consisting of sensors deployed randomly to oversee an inaccessible area. Sensors operate on a battery of limited power. The goal of WSN is to improve network lifetime and reliability with improved throughput. Limited energy resource is the main driving factor behind increasing the throughput. LEACH is one of the eminent hierarchical routing protocol in WSN. In this paper an improvement of LEACH has been suggested. In our proposed algorithm we adopt a technique in which the nodes are clustered at four different angles in a scalable network. A rectangular network is taken and different parameters like End to End Delay and Throughput are studied at each different angle. The protocol has been simulated in Network Simulator-2 (NS-2) and results are analyzed at each different clustering angle.
