Background: Wireless Sensor Networks (WSN) is an interconnected connection of two or more sensor nodes. A typical sensor node can perform Sensing, Computing and Communication.Objective: The core objective of this paper is to mitigate or to reduce the impact of the Hotspot effect in Wireless Sensor Network (WSN) by using a refined integrated MAC and Routing protocol and a quantification algorithm. Methods/Analysis: We are using a refined integrated MAC and routing protocol which divides the network into tiers. We also propose a quantification algorithm, which decides the optimum number of nodes in each tier to mitigate the hot-spot problem. The work is simulated in NS2. Findings: We simulated our work in NS2 and found that the proposed quantification algorithm along with Refined Integrated MAC and Routing Protocol outperforms SMAC in terms of network lifetime. Conclusion: The proposed protocol along with quantification algorithm increases the network life time and reduces the impact of the hotspot effect when compared with conventional MAC protocols.
