Case Number 103009 - Energy Aware Multi-path Routing for Uniform Power Consumption in Sensor networks
Contact: Geoffrey Pinski
Description: In a sensor network where every node has a limited energy supply, one of the primary concerns is to maximize the network lifetime through energy-efficient routing. The method of the present invention includes a deterministic traffic scheduling algorithm that balances the load over multiple paths between source and destination, in proportion to their residual energy. This protocol focuses on uniformly utilizing the resources of the network, rather than on optimality of routes.
Most existing sensor network routing protocols optimize for single or shortest path routing. This accelerates the failure of nodes lying along the often used optimal paths, thus adversely affecting the connectivity and hence life of the network.
