Abstract
In literatures, the performance of Wireless Mesh Network (WMN) has been analyzed by assuming the same quality for each hop. However, this assumption is hardly true in practice due to the physical obstructions of wireless link, especially for an indoor environment. Therefore, this paper revisits the analysis of WMN performance by taking the effect of physical obstructions into account instead of assuming an equally deterministic property for each hop. These obstructions cause the degradation of signal strength which relatively decrease the success rate of
transmission between hop to hop. This paper examines these physical concerns through the measured results and then the design of node locations can be achieved. Moreover, it is well known that the analysis of throughput in WMN has indicated the impact of near-far mesh locations. However, these examinations have neglected the quantity of user accessibility. Therefore, this paper presents the effect of user accessibility in terms of traffic intensity on WMN throughput. The simulations provide a substantial remark to realize the effect of physical obstruction and traffic intensity on designing WMN node locations.
