Wireless Mesh Network (WMN) is a developing technology which envisions a wireless backbone architecture (in place of the existing wired) to aid in providing internet connectivity to users at the residential and commercial level. In a WMN, the density of Mesh Clients (MCs) and the rate of traffic generated from each client are not uniformly distributed. Also, the traffic routes from a Mesh Router (MR) to the Internet GateWay (IGW) are multi-hop and multi-path in nature. Due to these factors, each MR has a different performance. For large scale WMN, maintaining such information about each MR in a centralized manner is not a practical and scalable solution. In addition, when new MCs enter the WMN they have little or no information about the performance of MRs. With scarce information, it is difficult for a MC to select a MR which can provide the best service. Therefore, MCs must directly request each MR in its vicinity to obtain information that can help make this decision. Since MCs have the freedom to select a MR of their choice, examining all nearby MR increases the chance of selecting a better MR suited for their application. However, often a MC has limited time available for selecting the MR. We propose three strategies that a MC can implement in making the selection of the MR - opportunistic, conservative and calculatingly-opportunistic. We study the performance of these strategies theoretically and statistically. We obtain the closed form solution for the conservative strategy which proves to be the best of the three strategies. We also identify the network parameter that can be used to rank the performance of an MR. We perform extensive network simulations to evaluate the performance of the strategies with various network configurations.
