Risha Vashist, Suniti Dutt . Minimum Spanning Tree based Improved Routing Protocol for Heterogeneous Wireless Sensor Network. International Journal of Computer Applications. 103, 2 ( October 2014), 29-33. DOI=10.5120/18047-8945
Abstract
Performing multiple tasks like data aggregation, processing and communication to other Sensor Nodes (SNs) or Base Station (BS) is a very attractive and effective attribute carried out by Wireless Sensor Networks (WSNs). As SNs have limited energy resources, storage capabilities and processing, the network layer protocol has therefore to guarantee reliable communication under these circumstances. Literature survey implies that hierarchical clustering and node heterogeneity are two key parameters that can ensure the enhanced lifetime of SNs. Keeping this in mind Improved Heterogeneous Routing Protocol (IHRP) is proposed. IHRP evenly distributes the load among clusters to ensure good network lifetime. A comparison is made between the performances of IHRP and Enhanced Heterogeneous Low Energy Adaptive Clustering Hierarchy (EHE-LEACH). Simulation results throw light on the improvement in lifetime of EHE-LEACH protocol by introducing this load balancing algorithm IHRP.
