Performance Evaluation of Multi-Hop Wireless Network with Point-to-Point Traffic Model and Fuzzy System

In wired communication, the point-to-point traffic model is used to determine the blocking probability for four different types of network topology: i) links are in series, ii) links are in parallel, iii) links are in a combination of series and parallel and iv) complex topology where links are neither series nor parallel like the delta-star network. In this paper, the concept of point-to-point traffic model is first applied in the multi-hop wireless link under small scale fading environment to determine the outage probability of four different configurations of the source to the destination link. The variation of the outage probability against signal to noise ratio (SNR) is shown analytically and verified with simulation for four topologies under both Rayleigh and Nakagami-m fading cases. The same concept is further applied in the fuzzy system to determine the probability of success of all the four topologies of multi-hop wireless networks. The analytical, simulation, and fuzzy outputs of this investigation are compared with those of previous reported works and close results are achieved. The results also reveal that the performance of the network under the proposed model depends on its topology unlike the series model of the conventional dual-hop wireless link of previous works.
