An improved ant colony routing algorithm for WSNs

Ant colony algorithm is a classical routing algorithm. and it are used in a variety of application because it is economic and self-organized. however,the routing algorithm will expend huge amounts of energy at the beginning. in the paper,based on the idea of dijkstra algorithm,the improved ant colony algorithm was proposed to balance the energy consumption of networks. through simulation and comparison with basic ant colony algorithms,it is obvious that improved algorithm can effectively balance energy consumption and extend the lifetime of wsns. © 2015 tan zhi and zhang hui.
