Due to the limited resources of the network transmission of large sized data can be a bottleneck in ad hoc network. The data delivery is done by selecting appropriate cluster heads. This kind of region diversity may be utilized to achieve higher energy efficiency. The authors divide the network into four regions. Node with highest energy in each region is selected as cluster head. Remaining nodes forwards their data to cluster head which buffers the data and forwards only one packet instead of all the packets received from other nodes. Therefore, the overall energy consumption is reduced in such a network.
