Wireless mesh networks will play an important role in the next-generation wireless communication systems as it can provide wide coverage and scalable broadband Internet access services. However, congestion in such networks may lead to throughput degradation, packet loss and longer transmission delay. Therefore, routing and traffic forwarding schemes which are aware of the congestion status of a wireless...
Wireless mesh networks used for broadband access may be equipped with multiple Internet gateways. Using airtime metric as the main criterion for path selection is an effective method for achieving load-balancing in such a multi-homed mesh network. In this paper, we describe how the radio-aware path selection using airtime as a metric can be implemented in order to achieve this functionality, based...
In the context of an EU FP6 project, ADHOCSYS, we have developed a reliable and cost-effective solution for broadband Internet access in rural and mountainous areas. This solution is built based on multi-hop wireless mesh networking technologies and covers many aspects such as routing, reliability, QoS, security, self-configuration, self-healing, remote network monitoring, power management etc. In...
While various wireless mesh networks are being deployed in urban areas and university campuses for diverse purposes, less effort has been devoted to use such networks for broadband access in rural and mountain areas. In this paper, we present a broadband Internet access paradigm using multi-hop wireless mesh networks which is currently being validated using a real-life pilot network deployed in a...
ADHOCSYS is an IST FP6 STREP project, supported by the European Commission, under the IST strategic objective "broadband for all". The project aims at providing reliable Internet broadband access in rural and mountain regions. This paper, starting from a general description of ADHOCSYS networks, introduces a methodology for multi-hop wireless network reliability assessment. The methodology...
