A Survey of Mobility Models for Ad Hoc Networks

Nowadays, there is tremendous research work about Ad Hoc networks, in which many efforts focus on the performance analysis and protocol behavior design. The selection of the most realistic and the most easy-to-implement mobility model is very crucial for the validity and feasibility of research. This paper presents several mobility models commonly used in Ad Hoc networks, representing mobile nodes whose movements are independent of each other and several mobility models that represent mobile nodes whose movements are dependent on each other. Through analyzing their associations and differences, we describe the application environments of each model and the qualification conditions of selecting models. The above work is expected to contribute to selecting mobility models or the design of new mobility models in order for the protocol design and planning of the network.
