Motion-based node behavior classification in routing for Ad Hoc networks

Mobile Ad Hoc networks, which are becoming the research hotspot, have wide application in battlefield, disaster area, extraordinary session and other special environments due to their independence on any network infrastructure. In this paper, a scheme of node behavior classification was proposed based on the analysis of mobile Ad Hoc networks´ own laws in practical application. Analytic hierarchy process is used in conjunction with fuzzy comprehensive evaluation to classify nodes´ behavior according to their motion state, so that the design complexity of networking protocols can be simplified and different set of networking protocols that best fit the circumstances can be designed correspondingly. The scheme is applied under an example network for rescue, where different routing policies are used by corresponding nodes classified by proposed node behavior classification scheme. Simulation results demonstrate the accuracy of the scheme.
