Abstract: WSNs nodes are mostly scattered and unable to replace batteries in time. As a result, the situations such as uneven network energy consumption and the premature depletion of important nodes are easy to come by. Therefore, a routing algorithm based on improved ant colony algorithm is proposed. It uses the network stratification band and restricts the search angle, introduces the medium distance and gradient function. And it also adds energy factor to the heuristic function to increase network cycle, enhance search capability, reduce energy consumption and avoid falling into local optimum first. Finally, the simulation experiment shows that the improved algorithm can overcome the shortcomings of the classical ant colony algorithm and achieve efficient real-time optimization routing.
