Research on Survivability Evaluation of Ad Hoc Network Connectivity
Abstract:
Connectivity is the basis and premise of the network services. Ad hoc network has the property of topological changes, which makes the connecting reliability the basis of its survivability evaluation. To compute the connecting reliability of Ad hoc network, it needs to analyze the whole system and evaluate the probability of keeping links available. Therefore, by applying the Markov process in Ad hoc network system modeling, the paper analyzes the connection availability of stead-state links when there are system exceptions. When the exception is thrown, it can analyze the phenomenon of instantaneous packet losses and delay at a network node by means of queuing theory. With a combination of steady-state availability analysis and nodes instantaneous non-response, the paper can draw a conclusion that evaluation indicators like connecting probabilities, packet losses and delay, can be used in survivability evaluation of Ad hoc network.
