Geographic Node-Disjoint Path Routing for Wireless Sensor Networks

One of the challenging issue in wireless sensor networks (WSNs) is efficiently route the multimedia information. In this letter, we propose an efficient geographic routing algorithm for multimedia data transmission such as audio, video, etc., in WSNs. It finds one near to shortest path per iteration and can be performed repeatedly iteration to find more on-demand shortest node-disjoint routing paths. This algorithm achieves high-throughput with low delay that is required for multimedia data transmission over WSNs.
