Research on node throughput in multi-radio multi-channel multi-rate wireless mesh network

This paper proposes a method to calculate the maximum effectual node throughput in multi-radio multi-channel multi-rate wireless mesh network (M3WMN) under fairness guarantee. The concept of bottle collision domain (BCD) is redefined. When the same traffic originated from each node is transmitted on the scope of each link's collision domain, the transmission time of BCD is the maximum one. After the maximum transmission time of BCD is calculated, the maximum node throughput is also derived. The simulation results indicate that the proposed method can analyze the maximum node throughput in M3WMN exactly.
