Connected Dominating Set-based Energy-efficient Distributed Routing Algorithm

Abstract

The broadcast storm problem in mobile ad hoc networks can be effectively alleviated by a connected dominating set-based virtual backbone network. However, the existing methods of connected dominating sets are not adapted to dynamic ad hoc networks. In this paper, a connected dominating set-based energy-efficient distributed routing algorithm is proposed. Furthermore, in order to select an appropriate relay forwarding node which reflects the energy efficiency of the dominating node and reduces its contribution to the entire network communication overhead, the additional coverage, residual energy and mobility of nodes are taken into overall consideration. To optimize the construction of network topology, the information entropy method is used to quantize each factor’s weight. The numerical results show that compared to the existing algorithm, the proposed algorithm can significantly reduce the network structure construction overhead, guarantee network connectivity, improve energy efficiency and extend the network lifetime.
