Aim at the problems of great overhead and the lower stability in Ad Hoc routing technology, an improved ant colony algorithm is proposed to study an ant-based Ad Hoc routing protocol. In our algorithm, the ant foraging, labor division and task allocation algorithm is the basic designation thinking.
