Multiple Ant Colony-based Wireless Sensor Networks Routing Algorithm

The development of wireless sensor network routing is being faced with the challenges of saving energy,improving reliability and increasing the lifetime of the network.In this paper,a Multiple Ant Colony based Routing Algorithm(MACRA) is proposed for routing optimization designing,in which the communication messages sent by nodes for searching the optimal route are treated as ants with limited life-span.Through the ants' movement and Populations' cooperation,the main routing path and multiple candidate routing paths can be distributedly obtained.The simulation results show the validity of MACRA.
