Research on the Link Topology Lifetime of Mobility Model in Ad Hoc Network
Ye Yao, Cai Wandong, Tian Guang-li · 2009
Link topology lifetime is not only an important metric to evaluate the dynamic characteristic of ad hoc network, but also is a direct and effective method to determine the time to perform ad hoc network measurement. This paper introduces the concept of ldquosnapshotrdquo to take the picture of link topology of three classical mobile mobility (i.e., RPGM, Freeway and Manhattan) respectively. Simulation results show that link topology snapshots method is not only a new idea to obtain the link topology lifetime of ad hoc network, but also the ratio of link connection, variety ratio of link topology and link topology lifetime curve could also be derived.
