摘　　要：提出基于混合整数规划MIP(Mixed Integer Programming)优化网络寿命方案.该方案考虑真实的WSN寿命优化框架,利用完整的链路层握手机制优化数据、ACK数据包的传输功率,并采用正态对数衰落路径衰落模型.此外,利用基于优化框架的MIP分析数据包长度对网络寿命的影响,并依据网络寿命合适选择数据包长度.仿真结果表明,提出的MIP能够利用数据包长度最大化延长网络寿命.The mixed integer programming-based optimization for network lifetime scheme is proposed in this paper.We present a realistic WSN lifetime optimization framework,and a complete link-layer handshaking cycle is modeled to select transmission power levels for both data and ACK packets.Log-normal shadowing path loss model is employed to take into account the effects of path losses.We utilized the developed Mixed Integer Programming（MIP）based on optimization framework to investigate the impact of data packet length on WSN lifetime.Simulation results show that the optimal data packet length is the maximum allowed length.
