Abstract
The random movement of nodes makes the dynamic topology structure be one of the most important characteristics in wireless multihop communication network, which makes the description and quantization of the dynamic property the very foundation of the design, simulation, and measurement for this kind of network. The distributions of the link duration and the topology duration will be derived and verified by simulations. Then, the topology flapping sensing method has been put forward based on TTL. Finally, the probability model of the topology stability in the measurement time has been established and calculated based on network tomography for wireless mobile multihop communication network in this paper. Simulating results verify the correctness and efficiency of the approach, which will provide the technique basis of research on the dynamic property and end-to-end measurement for wireless mobile multihop communication network.
Highlights
A wireless mobile multihop communication network is a self-configuring infrastructureless network of mobile devices connected by wireless links, with a typical example as mobile ad hoc network (MANET), vehicle ad hoc network (VANET), wireless sensor network (WSN), and so on
There are two ways to resolve the contradiction between the dynamic topology for wireless mobile multihop communication network and the fixed or already-known topology premise for network tomography [14, 15]: (1) to sense the topology flapping by data measurement and to make further deduction by the obtained information before or after the topology changing, (2) to shorten the measuring time to make the probability of topology flapping acceptable when the topology changing is imperceptible
Existing researches in link duration usually take the first definition, while the time distributed function should be adopted as the distributed function of topology duration with regard to wireless mobile multihop communication network with high dynamic property
Summary
A wireless mobile multihop communication network is a self-configuring infrastructureless network of mobile devices connected by wireless links, with a typical example as mobile ad hoc network (MANET), vehicle ad hoc network (VANET), wireless sensor network (WSN), and so on. Relevant studies indicate that the overall performance of wireless mobile multihop communication network is closely related to the adaptability of the network protocol to the dynamic property. The description and quantization of the dynamic property are the foundation of design, simulation, and measurement for wireless mobile multihop communication network [3]. The probability model of the topology stability in the measurement time will be established and calculated for wireless mobile multihop communication network.
