It is a hot topic to make full use of channel resources in the case of limited hardware resources on the Internet. Channel allocation in multi-interface multi-channel nodes can effectively solve the problem. Extending the single-interface single-channel OLSR protocol to multi-interface multi-channel OLSR protocol and distributed channel negotiation on multiinterface multi-channel OLSR protocol can...
This paper applies the theory of Evolutionary Game to QoS routing algorithm for wireless mesh networks which can not only improve the performance of traditional QoS routing protocols but also be able to reduce the cost of the routing algorithm.
Wireless Mesh Networks (WMNs) employ hybrid distributed mobile networks with instant deployment and capabilities Such as: self_healing, self_organization and self_configuration. These abilities make WMNs a likely technology for incident communication. An Incident Area Network (IAN) requires a reliable and efficient routing path in an environment, where infrastructure-based communications have been...
The key challenges of high-throughput data delivery in multi-radio multi-channel Wireless Mesh Networks (WMNs) are fluctuating channel conditions, dynamic traffic flows, co-channel interferences, congestion, etc. In this paper, we first formulate a mixed integer non-linear programming (MINLP) optimization framework that chooses, at each router, a number of outgoing link-channel pairs and allocates...
Because of the feature of hybrid wireless mesh network, hybrid routing protocol is the most proper routing protocol for this kind of network. Hybrid routing protocol is composed of proactive routing protocol and reactive routing protocol. The proactive one is adaptive for static mesh routers, and the reactive one is suitable for mobile mesh clients. Existing hybrid routing protocols all neglect the...
A Wireless Mesh Network consists of large number of mesh nodes. The message called Position-Aware and Secure Efficient Mesh Routing which has been sent from one node to another during the data communication. When the communication takes places among nodes, packet data is sent from one node to another node which can cause a chance of falling the nodes in the attackers trap and routing between the nodes...
Energy consumption has been a critical factor for mobile video applications. The quality of content delivery over wireless mesh networks consisting of such devices is also considered important. Existing energy-aware research and industrial effort focuses on reducing high-energy-consuming working periods of mesh devices at the expense of decreasing the quality of video content. This paper proposes...
Wi-Fi Mesh Community has turn out to be an important area community to offer internet to challenge the thrown domains and wireless link in metropolitan environments. In this paper, hassle of figuring out the most to be had bandwidth direction is targeted, which is an essential problem in helping pleasant-of-carrier in WMCs. Due to the concept of interference, bandwidth, which is a familiar challenging...
There has been rapid growth in the area of wireless communication by Wireless Mesh Networks (WMNs) where routing metric is the key metric to find the optimized route in WMNs. For obtaining optimal performance, integrating multiple performance metrics into a routing protocol is effective, as single metric will not be able to satisfy the thorough requirement of WMNs. This paper has proposed a new routing...
In this paper, we investigate the problem concerning about how to construct an interference-free multicast tree in the multi-channel multi-radio multi-rate wireless mesh networks with the goal of maximizing the number of clients served by the tree. This problem is referred as the profit-based multi-rate multicast tree (PMMT) problem. With the joint consideration of multicast routing, channel assignment...
Wireless Mesh Network is an emerging technology with great potential to become a Self-Sustained Network. Unlike the traditional networks that dominate the current communication system and rely on a large and expensive setup of wired/wireless access points to provide connection between users, the Wireless Mesh Network is formed by the user devices (referred as Nodes) which connect to each other to...
This paper presents a routing protocol called Load Distributed Mesh Routing (LDMR) that is developed for Wireless Mesh Network (WMN) with IEEE 802.11 standard. The LDMR protocol decides on the potential next hop nodes based on a quadrant and distance information. Then, the Next Hop Forwarding (NHF) decision is used to select the best next hop nodes based on Packet Success Rate (PSR) and maximum velocity...
Wireless Mesh Networks (WMNs) serve as a key enabling technology for various smart initiatives, such as Smart Power Grids, by virtue of providing a self-organized wireless communication superhighway that is capable of monitoring the health and performance of system assets as well as enabling efficient trouble shooting notifications. Despite this promise, the current routing protocols in WMNs are fairly...
We present a simulation-based study of the impacts of channel switching overhead on the performance of multicast in multi-channel multi-radio wireless mesh networks (MCMR WMNs). We study how channel switching overhead affects the performance metrics such as packet delivery ratio, throughput, end-to-end delay, and delay jitter of a multicast session.
We propose the multiple branch collection routing (MBCR), a routing method for wireless mesh networks (WMNs), and the main purpose of which is to reduce control communications. The virtual address of a node is generated when the node joins a network through MBCR. Nodes that join the network can obtain necessary information only from their neighboring nodes. When data are transmitted to a destination...
Recently, Wireless Mesh Network has become one of the most important wireless technologies around the world mainly because of its use in low-cost home broadband facility. Wireless mesh network spreading across a city or a university campus is now getting more prominence. In this scenario, there are needs for more efficient routing protocols for Wireless Mesh network which may support larger areas...

Software-Defined Networking (SDN) is a recent model of networking architecture which splits the network control from data forwarding functions. Most SDN solutions have in their scope the wired networks, but more recently, some attempts have been made to adapt SDN architecture for the context of wireless mesh networks (WMNs). In the present paper, we examine whether the use of the SDN paradigm in WMNs...
The contention based carrier sense multiple access with collision avoidance (CSMA/CA) was originally designed for single-hop networks. For CSMA/CA to be used in multi-hop distributed networks and to provide guaranteed data priority, the CSMA/CA needs to be optimised. An application is the smart grid consisting of different network domains with data of different priority levels. The IEEE802.11e standard...
