On the Event Reporting of Intra/Inter-Cluster Sensor Networks

Many protocols have been proposed to reduce energy consumption in wireless sensor networks and extend their lifetime. One of the most efficient class of these protocols is known as cluster-based routing protocols. In this paper, we consider a key issue that impacts the performance of this class of protocols. We call it Intra/Inter-Cluster Event-Reporting Problem (IICERP). We show that IICERP significantly degrades the performance of cluster-based routing protocols. Accordingly, we propose an efficient solution for IICERP (SIICERP). Thorough simulations have been conducted to show the performance of different cluster-based protocols with and without SIICERP. The simulations showed that SIICERP significantly improves the performance of cluster-based routing protocols.
