Wireless Sensor Networks consisting of nodes with limited power are deployed to collect and distribute useful information from the field to the other sensor nodes. Energy consumption is a key issue in the sensor's communications since many use battery power, which is limited. The sensors also have limited memory and functionality to support communications. Ant Colony Optimization, a swarm intelligence based optimization technique, is widely used in network routing. This paper describes a new routing approach for Wireless Sensor Networks consisting of stable nodes based an Ant Colony Optimization algorithm that explore the network and learn good routes, using a novel variation of reinforcement learning. Simulation results show that proposed algorithm provides promising solutions allowing node designers to efficiently operate routing tasks.
