Research of Directed Diffusion Based on Ant Colony Algorithm

The periodical diffusion of exploratory data adopts flooding diffusion in Directed Diffusion for wireless sensor networks.This way will inevitably lead to heavy traffic load and affect severely transmission performance of networks.An improved ant colony algorithm is proposed and applied to Directed Diffusion algorithm.The foundation of gradients is based on pheromone of ants and remain energy of nodes in new algorithm,which could balance the energy consumption of networks.The simulation experiment proves new method's feasibility,and the simulation results indicate that the new algorithm could effectively controls energy consumption of networks and prolong survivability of networks.
