Energy conservation of the sensor nodes is an important issue considered in the design of Wireless Sensor Network (WSN). So to extend the network lifetime several clustering approaches are used. Most of this clustering approaches facing hot spot problem. It is one of the key issues caused by the fact that the sensor nodes closer to the base station drain their energy quickly than other nodes as data of the entire network is forwarded to BS through them. In this paper, we are proposing an uneven multi-level grid clustering routing method to overcome the hot spot problem and to extend the network life time. Here this protocol divides the network into variable number of uneven grids based on the average energy level. At each period of time interval BS checks the average energy and sets the level of gridding. This method tries to set suitable number of grids based on current energy of network. It also guarantees suitable number of intermediary nodes to transmit the data to final destination; thereby reducing energy loss due to direct communication. The proposed protocol provides better solution to sudden energy hole creation and thereby improve network longevity.
