Abstract
The performances of the Ad Hoc networks vary rapidly because of the change of topology. How to describe and quantify this dynamic characteristic is the basis of designing and simulating the Ad Hoc network. Describing the move patterns of the nodes is the customary way. This way is called mobility model, which have been found several faults. In this paper, Topology Variety Model (TVM) is proposed to describe the dynamic characteristic from the link layer by means of link duration and connectivity probability and it is realized in the simulator ns-2. The simulation results indicate that with appropriate PDF of link duration for scenario, TVM can replace mobility model to simulate Ad Hoc networks. Meanwhile, the relationship between mobility and TVM is studied. The influence of dynamic on network performance is simulated based on TVM.
