Wireless Mesh Networks (WMNs) with chain topologies are very useful in road and railroad transportation or in tunnel and mine applications. The proposed protocols for WMNs usually support best-effort traffic or some kind of Quality of Service (QoS). However, some applications such as remote-controlled machines in industrial control networks have Hard Real-Time (HRT) requirements, i.e., strict deadlines...
Wireless mesh networks are rapidly deployable for many applications. The throughput of such a network depends on the schemes used for medium access control. In this paper, we present some of our latest results on the (intra-network) throughput of large-scale networks. In particular, we show a comparison of the throughput between the opportunistic synchronous array method and the slotted ALOHA under...
Wireless mesh networks (WMNs) are an alternative technology for last-mile broadband Internet access that can support broadband services. However, for a WMN to be all it can be, considerable research efforts are still needed. For example, the available MAC and routing protocols are not scalable; throughput drops significantly as the number of nodes or hops in WMNs increases. Thus, existing protocols...
In 2003, interests in the Institute of Electronics and Electrical Engineering (IEEE) 802.11 Working Group (WG) led to the formation of Task Group (TG) "S". 802.11s develops a Wireless Mesh Network (WMN) amendment. Unlike existing Mesh products, 802.11s forms a transparent 802 broadcast domain that supports any higher layer protocols. Therefore, 802.11s provides frame forwarding and path...
In recent years, the wireless mesh network (WMN) attracts the interest of many people as a new broadband Internet access technology. However, increasing throughput is still an open and challenging research issue. One potential solution is to enable transceivers to utilize multiple channels dynamically. However, most of existing works do not consider the routing issue, and trivially use some popular...
The use of WMNs as backbone for large wireless access networks imposes strict bandwidth requirements. It is therefore necessary to study and quantify the capacity of such systems. In this paper, we argue that the capacity of WMNs should be addressed in the context of fairness to ensure proper operation of WMNs. Among the fairness schemes, max-min fairness allows fair and efficient use of network resources...
