ALGORITHM DESIGN FOR RELIABILITY ANALYSIS IN MOBILE COMMUNICATION NETWORKS

The environmental conditions, the changing locations of the mobile hosts and the changing structure in the wireless computer network can easily affect and change the system reliability. Nevertheless the changing locations of a mobile node are considered the main problem to obstruct analyzing the reliability in a definite traffic setting of the system. In this study, the classical two-terminal reliability is extended for wireless computer network. To this end, Markov Chains are used as the predictor for the changing locations of the mobile node(s) and a set of algorithms is proposed to analyze the reliability of the computer networks including mobile nodes which may form different conditions related to its starting and finishing situation. Furthermore some flexible solutions such as the definition of a blank position for the mobile node which is not in the range of any access point are proposed for the different applications of the computer networks. In order to verify the algorithms, a simulation is performed and the results are evaluated.
