Equilibrium energy routing algorithm based on ant colony system for WSN
一种蚁群竞争WSN能量均衡路由算法

An improved ant colony competition energy routing algorithm named AERA was put forward, which aimed at the special requirement in network congestion and energy controlling for Wireless Sensor Network (WSN). This algorithm could, by taking advantage of Ant Colony System (ACS), accelerate the constringency speed of routing on shortcut and take the balance of nodes energy into account. It imported the multiple ant colony competition mechanism too. The pheromone and energy of network nodes were combined to affect the pheromone concentration in optimization path, which could avoid network congestion and balance the energy consumption among the nodes. Thus it could prolong the lifecycle of the whole network. The feasibility of this algorithm has been validated, and the results of experiment have been presented.
