Abstract: In order to take advantage of base station mobility for prolonging WSN lifetime and determining the optimal mobility pattern, Mixed Integer Programming-based Gaussian Base Station Mobility(MIP-BSM) scheme is proposed in this paper. The paper firstly chooses a fairly large standard deviation value and generates the candidate base station positions according to this standard deviation and zero mean. Secondly it runs the MIP model for the network lifetime optimization by using the candidate base station positions. Simulation results show that MIP-BSM gives the longer network lifetime values than random mobility.

摘要: 为了最大化延长无线传感网络寿命,设计最优的基站移动模型,提出了基于混合整数规划MIP(Mixed Integer Programming)的高斯移动方案MIP-BSM(MIP-based Gaussian Base Station Mobility)。该方案首先选择较大的标准方差,并依据此方差和零均值产生基站的候选位置,然后使用这些候选位置执行MIP模型,获取基站移动的最优位置。仿真结果表明,与随机移动模型相比,MIP-BSM能够获取更长的网络寿命。
