Abstract: Simulation is an indispensable tool in protocol design and evaluation. Typically, simulations of mobile wireless sensor networks rely upon mobility models. This paper presents a smooth Gauss-semi-Markov mobility model (SGM) that can reflect the realistic node movement and has more controllable parameters. Time stationary average speed and uniform spatial node distribution of SGM are proved by Markov process and renewal process theory. Thus, SGM model can be applied to simulation of mobile wireless sensor networks. Key words: wireless sensor networks; mobility model; simulation; average speed; spatial node distribution 摘 要: 在总结现有实体随机移动模型优、缺点的基础上,提出一种能够较好地反映现实节点运动规律的参数
