Wireless multimedia sensor networks are widely used in the information acquiring and processing. Potential applications of multimedia sensor networks span a wide spectrum from military to industrial, from commercial to environmental monitoring. These applications may demand high bandwidth and are extremely delay-sensitive. Multipath routing is one of appropriate solutions for multimedia data transmitting in wireless sensor networks. In this paper, we address the issues of interfering multipath in wireless multimedia sensor networks and propose a new noninterfering multipath geographic routing scheme. Comparison with interfering multipath scheme and simulation results in communication level show that the new scheme can effectively solve the interfering problem of multipath and reduce the average end-to-end packet delay.
