Abstract: To reduce the energy consumptions of wireless sensor network nodes (WSN), avoiding communication conflicts caused by different nodes simultaneously using shared channel, this paper proposes a dual-channel routing algorithm for sensor networks (CORA) based on Ant Colony optimization strategy. The algorithm can reduce the nodes mutual inhibition competition in channel contention by using dual channel communication model; compress the path finding ranger for ant colony through the maximum infection ball to reduce the energy consumption for network; propose a two-tier network with combined dispatching to effectively abate network congestion by means of layered graph. The simulation results show that compared with an energy-efficient routing algorithm based on Ant strategy and an energy-efficient routing algorithm based on Ant Colony optimization strategy, the CORA algorithm can lower down the network congestion to 17 % and reduce message conflicts between data packets and control packets, effectively reducing the energy consumption for average communicating time of packets and network.

 

Keywords: Dual-channel; Ant colony strategy; Wireless sensor network.
