Path Finding and Selection Scheme Using Fuzzy logic For Multi-Hop Cooperative Mesh Network

Till date, a great piece of work has been done on bringing cooperation in wireless networks to achieve quality of service. However, the increased number of relay nodes used in these models leads to an overall costly and dense network. The prime focus of this research paper is to reduce the number of relays and make the lesser available relays intelligent via Fuzzy logic with an aim of increasing the system performance in terms of symbol error rate (SER). Hence we propose a path finding and selection technique for multi hop cooperative mesh network based on fuzzy logic with three input fuzzy parameters. The performance of suggested scheme is evaluated in terms of symbol error rate (SER) in three fading channels that is Nakagami, Rayleigh and Rician fading channels. BPSK is used as modulation scheme while software that is used for simulation is MATLAB.
