Research and simulation of DSR based on ant colony algorithm

In order to prolong the life span of WSN and avoid the emergence of early dying nodes in clusters,ant colony algorithm is used to optimize the dynamic source protocol.During the research of cluster partition and head picking,researchers dynamically trace the condition of nodes in WSN,balance the translational speed and rest energy of nodes to choose the right cluster head and to set down the steady-going radio propagation radius,then accord to the radius to determine the size of mesh and finally realize the steady information translation and the effective use of energy.The simulation results show that,compared with LEACH and CDSR,the AC-DSR can improve the information transfer efficiency,equipoise the notes' energy cost and extend the network's life in a more effective way.
