Wireless Mesh Networks (WMNs) research has matured in recent years and implementations are being tested around the world. In a WMN, participating nodes are automatically configured allowing them to communicate among their peers via multiple hops when no direct physical connectivity exists. Increasing demand for real-time multimedia content poses a challenge for the typical WMN routing protocols such...
The most widely used standard for wireless networks is the IEEE 802.11. In 802.11, dense deployment of Access Points (APs) is needed to meet customers' demands. The installation of multiple access points is expensive and not convenient because of Ethernet wiring from access points to backhaul network access modem, hub, etc. Wireless mesh network (WMN) is an emerging technology; presented mainly as...
Wireless mesh networks (WMNs) have attracted increasing attention and deployment as a high-performance and low cost solution to last-mile broadband Internet access. Wireless mesh networks have emerged as a potential technology for next-generation wireless networking. WMNs have been widely accepted in the traditional application sectors of ad hoc networks because of their advantages over other wireless...
In recent years wireless mesh networks have been deployed and grown in popularity in many metropolitan areas. The deployment of such networks has allowed clients to gain access to publicly available broadband networks. The lack of standards and support for multicasting over wireless mesh networks makes this area very challenging as well as providing much scope for improvement. For first time in this...
One of the most promising wireless technologies is Wireless Mesh Network (WMN). The aggregate capacity of wireless mesh networks can be improved significantly by providing each node with several Wireless Network Interface Cards (WNICs) and by using multiple channels in order to minimize the interference and to provide high performance in such networks. However, multiple WNICs in each node requires...
Wireless networks are a very challenging communication technology since their ability to be set everywhere and whenever. Among the several types of wireless systems, a new class of networks is gradually emerging: Wireless Mesh Networks (WMNs). A WMN is a distributed communication infrastructure organized in a mesh topology, which handles multi-hops connections and is capable of provide dependable...
In this paper we consider multi-hop wireless mesh networks intended to provide Internet connectivity to both end users and hotspots. In such networks mechanisms for provisioning QoS for delay sensitive flows arise as an important topic. In this context, we focus on the non-bifurcated (single path) routing of such flows as a means of allowing all packets in any flow to receive uniformly controlled...
Initial entry during deployment requires tactical networks supporting voice, video, and data requirements to be established quickly given little existing telecommunication infrastructure. Wireless mesh networks using contention-based medium access control (MAC) appear to be an easy off-the-shelf solution, but their performance is lacking for support of such diverse high-bandwidth low-latency requirements...
Wireless mesh networks have recently gained a lot of popularity due to their rapid deployment and instant communication capabilities. Special routing protocols are employed, which facilitate routing between the Mesh Routers as well as between the Mesh Routers and the Mobile Nodes. This work addresses a framework of packet routing in the wireless mesh network. We investigate a cross-layer solution...
This paper proposes a fast forward medium access control protocol (FFMAC) for quality-of-service (QoS) guarantee in multihop IEEE 802.11s wireless mesh networks with multiple channels. To the best of our knowledge, the proposed protocol is the first one which considers the multihop and multichannel issues simultaneously. It provides higher priority for real-time applications, while remaining the distributed...
