An Effective Heuristic DSR
In this paper, we come up with an optimal DSR based on ant colony algorithm to improve the operational efficiency of wireless sensor network. Firstly we introduce the concepts of virtual grid and effective information propagation radius, then accord to the sensor’s translational speed and the rest energy to estimate the sensors’ persistence of life; besides, depend on the radius of effective information propagation we set the size of virtual grid and use this virtual grid as the unit to divide clusters. Finally, we realize the goal of steady information translation and effective energy usage. Under the same simulation environment, we compared the running results of DSR, LEACH and HDSR, the results illustrate that HDSR is not only able to improve the efficiency of information transportation but also equipoise the energy cost, it effectively increases the robustness of WSN.
