Wireless Mesh Networks (WMNs) are data networks with mesh topology formed by nodes that establish and maintain the network connectivity automatically. They also provide a cheap, quick and effective way for building wireless data networks in urban, suburban and rural environments solution. These require a routing protocol such as the IEEE 802.11s standard. For proper operation, in addition to routing, the WMNS require support of Quality of Service (QoS), that is, the ability of the network to guarantee a certain level of performance to a flow, mainly for multimedia traffic. In this paper we evaluate the in Nodes of a Wireless Mesh Network based on IEEE 802.11s developed with OpenWRT (an open source firmware) measuring parameters such as bandwidth, jitter and higher packet loss, depending on the type of information stream. The importance of this study is to verify the ability to create low-cost WMNs in rural, inaccessible environments, and reduce the digital divide.

Deployment of video communication services over mobile ad hoc networks faces numerical obstacles since the networks are characterized by limited and unpredictable bandwidth. Following the tenet of service-orientation, this study proposes a cross-layer design for fine-grained adaptive transmission of real-time video over time-varying channels. Specifically, the sender accurately estimates the current effective bandwidth by observing its transmission buffer and negative acknowledgments (NACKs) from the receiver. Information on route quality provided by routing protocols may also be exploited to control the real-time stream efficiently. At the same time, the sender handles NACK messages to predict route goodness and orders retransmissions for improving video quality. We have evaluated the performance of the proposed design by both simulations and experiments of ad hoc nodes delivering H264/AVC, which consistently demonstrated the soundness and feasibility of the framework with respect to video quality and resource utilization.
