Wireless Sensor Network (WSN) are ad - hoc networks, comprising of light weight sensor nodes, which are traditionally operated by battery power. Due to static power source and deployment in hostile environment, it becomes a challenging task to replenish the power source or change batteries. Thus, the network has to optimally utilize the existing power source to improvise the lifetime of these sensor nodes. The congestion zone problem arises near the sink, due to frequent utilization of available energy by these nodes from the energy utilization equation of lifetime. In this paper, the uneven deployment mechanism to the congestion zone has been addressed to improvise the lifetime and collectable information of a network. As a result, it is observed that, the maximum achievable upper bound on collectable information and network lifetime has fairly improved.
