Energy efficeient interference aware Multipath Routing protocol in WMSN

Automated information gathering in military, industrial, environmental and surveillance applications which requires improved QoS guarantees as well as high reliability is well supported with Wireless Multimedia Sensor Networks (WMSNs). In this paper, we propose a more reliable energy efficient multi-path routing scheme for multimedia-traffic. The proposed protocol quickly chooses partial disjoint paths in case of node failure to minimize routing overhead. Hence increases the reliability of the packets reaching the destination with minimum delay. Extensive simulations are carried out to show that proposed protocol achieves an efficient tradeoff among reliability, energy consumption and end to end delay. It provides higher packet delivery ratios and lower routing overheads compared to the Maximally Radio disjoint Multipath Routing (MR2) and Hop Count Multipath routing (HCMR) protocols.
