Distributed Fault-Tolerant Topology Control in Cooperative Wireless Ad Hoc Networks
IEEE Transactions on Parallel and Distributed Systems(2015)
摘要
Current researches on topology control with cooperative communication (CC) in wireless ad hoc networks have focused on network connectivity, path energy-efficiency and node transmission power reduction. However, fault-tolerance related issues have not been adequately addressed. In this paper, we propose a CC-based scheme to achieve more efficient fault-tolerant topology control. We first define k-connectivity under the CC model and then design a distributed scheme for building a t-spanner with k-connectivity of an arbitrary communication network. Simulation results confirm that the proposed scheme can tolerate node failures as well as exploit the advantage of CC to achieve path energy-efficiency and lower power consumption of the network.
