Performance reliability evaluation for mobile ad hoc networks

The reliability of the mobile ad hoc network (MANET) is receiving increasing attention. Previous works are mainly focused on the connectivity reliability of the MANET; however, its performance reliability has not been considered. In the MANET, the paths connecting two nodes are prone to continuous changes due to the mobility of nodes, which can result in a huge uncertainty on the transmission performance. Thus it is necessary to research the evaluation method of the performance reliability of the MANET. In this study, the transmission reliability is defined to measure the reliability of the transmission performance of the MANET. The impact of interference on the transmission reliability is considered. The topology optimization of the MANET is studied based on the transmission reliability, and genetic algorithm is adopted to solve the optimization problem. In the numerical example, the effects of the involved parameters on the transmission reliability are discussed, and some applicable conditions of the optimal design are analyzed for practical applications.
