Hierarchical multi path routing protocol for wireless multimedia sensor networks

Abstract

Wireless multimedia sensor network (WMSN) deals with transmitting multimedia traffic over a long range in multi-hop along multiple paths. This is so for achieving the objectives of Quality of Service (QoS). In clustered routing, the load on the cluster head nodes increase and the energy consumed at the cluster head nodes lead to energy depletion of that node which degrades the network performance. The proposed protocol focuses on QoS and energy efficiency in WMSN by considering the hierarchical deployment of heterogeneous nodes. This protocol makes use of hierarchical structure of powerful cluster head nodes and the optimized multiple paths to support reliable and energy efficient multimedia transmission in WMSN. The reliability and life of the network increases because of the fault tolerance and load balanced feature of the protocol. Simulation results describe a significant performance improvement in terms of energy consumption of the nodes and the QoS parameter.
