Fault-Tolerant Power-Aware Topology Control for Ad-Hoc Wireless Networks

\Minimizing energy consumption and ensuring fault tolerance ale two important Issues in ad-hoc wireless networks In this paper, we describe a distributed topology control algorithm which minimizes the amount of power needed to maintain bi-connectivity The algorithm selects optimum power level at each node based on local information only The resultant topology has two properties. (I) it preserves the minimum energy path between any pair of nodes and (2) it ensures fault tolerance by maintaining bi-connectivity By presenting experimental results; we show the effectiveness of our proposed algorithm.
