摘要: Sensors consume most of their limited energy on transmitting the collected information to sink node. Therefore, determination sensor-to-sink flow routes becomes important for survivability sensor networks. Besides, using mobile node can extend network lifetime by balancing sensors consumption. In this paper, we studied maximization in wireless networks (WSNs) jointly considering mobility and routing. addition, take advantage multiple nodes further improve lifetime. A Mixed Integer Linear Programming (MILP) formulation is proposed find optimal routing pattern. a heuristic approach achieve near result polynomial time. The performance evaluated both single multi-sink Numerical results indicated that approaches increased significantly as compared not only fixed model but also conventional models.
