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.
