Abstract: Complex parameter design is an important issue in Gauss-Markov mobility model (GM model). In this paper, we firstly discuss the parameter characteristics of GM model. Research results show that the initial speed of a node has little influence on its out-boundary rate and coverage rate. The impacts of randomness tuning parameter a, border threshold l, step time t and average speed s on a node’s out-boundary probability and coverage rate are then analyzed. After that, we can get the following conclusions: an ideal range, ? ? (0.4, 0.7), is recommended; the design of border threshold l should take the maximum speed of each node, step time t and tuning parameter a into consideration; other model parameters should be designed according to the performance requirements after comprehensively considering the realistic application scenarios.
