Balancing the network traffic load is a serious problem in wireless sensor network. The data generated in a wireless sensor network is stored on the sensor node and accessed through Geographic Hash Table (GHT). GHT is used to retrieve the data from nodes. The previous approaches allow balancing network load by changing the geo-routing protocol. In the authors' paper, they have designed two new approaches called analytical and heuristic. In analytical approach the destination density function yielding quasi-perfect load balancing under uniformity assumption.
