The Effects of Interference on Video Quality Over Wireless Sensor Networks
Multi-path routing appears to be an essential feature for supporting the characteristics of wireless multimedia sensor networks. In fact, using multiple paths between the source and the destination can provide adequate network resources required by such networks. However, the effect of wireless interferences between paths severely affects the performance of this approach. In this paper, we propose a simple interference-aware multipath routing protocol and study the effects of inter-path interferences on the received video quality in the context of wireless multimedia sensor networks. We show, through simulations, that minimizing interferences between the transmission paths can provide necessary bandwidth to support multimedia applications when small frame rates are used.
