A simulation and research of routing protocol for ad hoc mobile networks

In traditional methods for accessing Internet in mobile wireless environment, users can access to fixed networks by one hop (without multi-relay) based on Broad Band access networks'. In some special applications, messages from source users can only arrive at destination terminals by multi-relay (multi-hop) among several mobile users because wireless network is infrastructural, which is so called Ad hoc networks. Some up-to-date research results in table driven routing and on-demand routing for ad hoc mobile networks are proposed in this paper. In the mentioned two kinds of routing protocols, DSR and DSDV, this paper not only introduces the contents of the routing protocol, but also points out their advantages and drawbacks, and evaluates these protocols based on a given set of parameters such as deliveration, end-to-end-delay, meanhop and load. Based on the simulation experiments this paper has analysis and identified the most suitable condition to use the above routing protocols efficiently. At the same time it pointed out the principles to choose the suitable protocols under different using conditions. Finally, the authors suggest the research direction in routing for ad hoc mobile wireless networks in the future.
