A cooperative game theoretic solution for lifetime maximization of WSNs in sequential estimation
Sudharman K. Jayaweera, Kamrul Hakim · 2010
In this paper, the problem of sequential estimation and lifetime maximization of a wireless sensor network (WSN) is formulated in a cooperative game theoretic framework. This framework allows addressing problems of fair resource allocation for sequential estimation at the Fusion center (FC) of a wireless sensor network as a solution of a cooperative game. We propose a simple game theoretic solution to power allocation problem for sensor nodes such that the obtained solution leads to increased lifetime of the WSN. Simulation results show that the proposed solution achieves target estimation quality at the FC, and at the same time lifetime of the overall sensor network is increased.
