Energy-Aware Georouting With Guaranteed Delivery in Wireless Sensor Networks With Obstacles

The authors propose a novel routing protocol, EtE, that is both energy efficient and guarantees delivery. EtE is general enough to be efficiently deployed in a network with arbitrary topology (networks with obstacles and holes). It is a two-phase routing protocol that uses an energy optimized greedy routing followed by an energy efficient Face routing scheme when a local minima is encountered. To the best of their knowledge, EtE is the first and only algorithm that uses an energy efficient Face routing. It is achieved by the integration of the dominating set to optimize the paths edge length used in the routing process.
