Interference-Aware Multipath Routing for Video Delivery in Wireless Multimedia Sensor Networks

Multiple paths are mainly used in order to achieve higher throughput and reduce the end-to-end delivery latency as well. However, the overall network performance greatly suffers from the available interference between paths, even if node disjoint multipaths are used. This problem is highlighted more when dealing with transmission of the video data where the timeliness is of primary concern. In this paper, we propose a novel Interference-Aware Multipath routing for Video Delivery (IAMVD) in the realm of wireless multimedia sensor networks. It constructs multiple paths while considering the effect of different QoS requirements of multi-priority packets, without needing any hardware support for location information. Simulation results in NS-2 show that our proposed protocol has much better performance than the existing ones in terms of frame delivery ratio, throughput, energy consumption, and frame delivery latency.
