Wireless Mesh Networks (WMNs) are a variant of ad-hoc networks that have recently received increasing attention. They are a promising technology for a wide range of applications for the reason of their cost-effectiveness, self-configuring and self-healing nature. Routing protocols are a key component of WMNs, as they are responsible for discovering and establishing end-to-end, often multi-hop, paths between nodes in dynamic environments. In this paper, we evaluate the performance of the Ad-hoc On-demand Distance Vector (AODV) protocol for hybrid WMNs, which are a special type of wireless mesh network that are comprised of both static infrastructure nodes as well as mobile client devices. The results obtained from our testbed network indicate that AODV performs effectively in hybrid WMNs and is able to handle a high volume of traffic with minimal latency. While existing works on performance evaluation of adhoc and WMN routing protocols are typically performed either via simulations or via experiments on test-beds. Comparisons of results from both methods are rarely provided. One of the key contributions of this paper is the validation of our simulation results by performing experiments on a real WMN test-bed using the same scenario and mobility pattern. Our results show a reasonably good correlation between the simulation results and our test-bed measurements and we are able to explain the observed variations. Our work serves as a base line result for the exploration of larger and more complex network topologies.
