Routing metrics in wireless mesh networks: a Monte Carlo simulation approach

Wireless Mesh Networks (WMN) can extend the wireless technologies with respect to their coverage. In order to properly plan a WMN, it is not always easy to install it directly as the topology and configuration of some parameters may not be optimized leading to excessive costs and inefficient network services. Therefore, it is necessary to evaluate WMN performance with different configurations of parameters and different topologies without the need to deploy them. The paper presented here proposes the use of Monte Carlo simulation in order to evaluate the performance of a WMN in order to satisfy acceptable QoS parameters for routing metrics, such as ETX and ETT. Results presented show that the method is quite effective in testing several scenarios and configurations in order to obtain a good feasible solution before installing the network.
