Abstract
As part of the next generation Internet, Wireless Mesh Networks have emerged as a key technology to deliver Internet broadband access, wireless local area network coverage and network connectivity at low costs. The capacity of a wireless mesh network is improved by equipping mesh nodes with multi-radios tuned to non-overlapping channels. Hence the data forwarding between two nodes has multiple selections of links and the bandwidth between the pair of nodes varies dynamically. The new technology makes mesh nodes cognitive, thus a mesh node is able to adopt machine learning mechanisms to choose the possible best next hop which has maximum bandwidth when it intends to forward data. In this paper, we present a new forwarding algorithm by which a forwarding node dynamically select its next hop with highest potential bandwidth capacity to resume communication based on learning algorithm. The efficiency of this approach is that a node only maintains three past status, and then it is able to learn and predict the potential bandwidth capacities of its links. Then, the node selects the next hop with potential maximal link bandwidth. Additionally, a geometrical based algorithm is developed to let the forwarding node figure out the best forwarding region in order to avoid flooding. Simulations demonstrate that our approach significantly outperforms peer algorithms.

One is congestion control and fuzzy logic with machine learning for wireless communications, say Fuzzy Logic
Summary
Wireless mesh networks(WMNs) have emerged as one of the key technologies for wireless communications. They are undergoing rapid development and have inspired numerous applications because of their advantages over other wireless technologies. The networks, such as WiFi, 802.15, 802.16 and sensor networks, can be integrated into the WMN through gateways and mesh routers. Either stationary or mobile, can form client mesh networks among themselves and with mesh routers. WMNs are anticipated to significantly improve the performance of ad hoc networks, wireless local area networks (WLANs), wireless personal area networks (WPANs), and wireless metropolitan area networks (WMANs).
