摘要
The availability of network communication services is an important evaluation standard to measure the ability of the network to meet the user’s business needs.The current related research mostly focuses on the evaluation of network reliability,which cannot reflect the logical relationship between failure/maintenance and network performance parameters.Mobile Ad Hoc Network is a multi-hop,centerless and energy-constrained distributed system.Due to the dynamic change of communication environment and the instability of wireless link,Ad Hoc Network is facing great challenges in service availability.In this thesis,a fault-based quantitative evaluation model of traffic availability in Ad Hoc networks is proposed.By studying the multi-state Markov fault model of communication networks and the performance analysis of delay index based on CSMA\CA protocol,the quantitative evaluation of traffic availability in Ad Hoc networks is realized.And the availability of tactical unit network under different typical network configuration conditions is analyzed through experiments.
