For simulations, we used ns-3 and Optimized Link State Routing (OLSR). We compare the performance of Distributed Coordination Function (DCF) and Enhanced Distributed Channel Access (EDCA) for exponential distribution of mesh clients by sending multiple Constant Bit Rate (CBR) flows in the network. The simulation results show that for Hybrid WMN, the throughput of both MAC protocols is higher than I/B WMN. The delay and jitter of Hybrid WMN are lower than I/B WMN. The fairness index of I/B WMN is a little bit higher than Hybrid WMN.Peer ReviewedPostprint (author's final draft
