Abstract
A system and a method for organizing optimal paths in a sensor network. Optimal paths are determined based on an objective function that balances the performance and energy consumption of sensor nodes. Each sensor node stores and updates pheromone values and aging factors associated with each of its neighbor nodes. The pheromone values provide an indication of the speed of a given path, while the aging factor represents the use. Paths are compared using these variables and an optimal path is selected on each transfer so that the load is spread across a variety of sensor nodes, increasing network life.
