In multitier visual sensor networks, the constraints faced during node communication is horizontal collaboration and limited life time of visual sensor networks. During horizontal communication between the visual sensor nodes, there is a need for selecting the number of neighboring nodes in the region having more or less common field of view to reduce the redundant information transmitted to the base station. This work introduces an overlapping based energy aware approach for selecting the node which will be transmitting the image to the base station. This novel approach helps in efficient processing and to increase the life time of visual sensor networks. Analysis carried out with the proposed approach shows that the network lifetime increases by 70%.
