Abstract:Due to the wireless sensor network (WSN) is provided by battery, energy management becomes a fundamental problem in such network. In view of the maximization lifetime problem of the restricted multiple mobile base stations network, we will propose the MMBEC algorithm in this paper. Since the mobile station was limited by the actual road and its own energy, we first balance the energy load of base stations by sub loops division, and then we move the base stations periodically in order to achieve the data traffic balance of nodes adjacent roads. Because the balancing of sub loops problem belongs to NPC problem, in this paper we proposed an approximation algorithm for the purpose of finding an approximate solution. Control the mobile base stations stay periodically ensures the energy of the nodes adjacent to roads exhaust almost at the same time, and therefore, prolong the lifetime of network. The results of simulation experiment show that the algorithm prolongs the lifetime of network and improves the throughput capacity of data when compared with the existing algorithms.
