A Wireless cellular Ad-hoc network is a collection of wireless mobile hosts that makes a momentary network with or without a centralized management or wired infrastructure. This is the era of growing smart phone technology people are dependent on the service provided by phone so in this scenario providing quality of service is essential task for service providers. Smart phone is movable device user...
Wireless cellular network has recently emerged as one of the popular technologies for the next generation network due to the development of smart phone technologies which resulted in high mobility of user and achieving Quality of Service (QoS) for application like video conferencing, video streaming etc… requires an efficient multicast routing protocol which is one of the most key performance metrics...
Congestion avoidance is a vital part in improving the Quality of service (QoS) in Wireless Mesh Network (WMN). A preventive congestion avoidance algorithm is proposed in this paper which predicts the congestion before it really happens in the network by using different statistical analysis models which analyze historical traffic data in the network with some level of certainty to predict the future...
This paper evaluates a routing protocol called Better Approach to Mobile Ad hoc Networking (B.A.T.M.A.N.) for a wireless mesh network. Specifically, this paper describes the practical deployment of the outdoor wireless mesh network using a PC Engine™ embedded application called the ALIX3 series system. The actual measurement of the outdoor wireless mesh network performance is the utmost importance...
Wireless Mesh Network (WMN) is an emerging and practical wireless solution for metropolitan area networks to provide community broadband Internet access services by organizing and configuring nodes in the network efficiently and dynamically. In this survey, the concept of wireless mesh network has been described briefly as an emerging technology to provide Internet in large areas. Accordingly, the...
Cooperative caching is a desirable approach to achieve efficient data access in multi-hop wireless networks. Existing cooperative caching algorithms mostly focus on cache placement. Another key issue, cache consistency, has not been adequately addressed. In this paper, we propose CACC, a cooperative approach to maintain cache consistency for wireless mesh networks. CACC combines push and pull by making...
This paper proposes cooperative opportunistic routing (COR), a throughput improvement scheme for the cooperative opportunistic routing in multi-hop wireless mesh networks (WMNs). We investigate the two major issues in opportunistic routing, the selection and the prioritization metric for the candidate set. The COR is presented to select and prioritize the candidate node with minimum expected cost...
Station association information, such as an associated mesh router is required to support communication between legacy stations in Wireless Mesh Networks (WMN). Current IEEE 802.11s draft standard specifies two mechanisms to maintain the station association information: Proxy Registration Procedure (PRP) and Association Discovery Protocol (ADP). Each of them has structural limitations in that mesh...
In this paper carried out a review and classification of existing channels frequency distribution methods in multichannels mesh network of IEEE 802.11 standard.
The earthquake site communication technologies are very important for the post-earthquake emergency and rescue work, with high requirements for convenient setup and stable data transmission. According to the real requirements, methods to establish the earthquake site communication network based on wireless mesh network (WMN) are proposed in this paper. A WMN is a special type of wireless ad hoc network...
Wireless Mesh Networks (WMNs) is a part of Ad-hoc network. WMNs is very emerging and fast growing technology in wireless field. WMN has many research fields and one of them is routing field.

A lot of work has recently been published regarding metrics that could identify high quality paths in Wireless Mesh Networks (WMN). While results are encouraging, no optimal strategy has yet been identified that could estimate link quality and incorporate both the link reliability measurements as well as the bandwidth capacity. Furthermore, link estimation remains an open problem. Considering multi-user...
To tackle an inherent security weakness of wireless environments, we propose the implementation of a reputation procedure onto the routing protocol Ad-hoc On Demand Vector routing (AODV). This procedure relies on the overal cooperation of nodes taking part to the Wireless Mesh Network. Each node associates a reputation value to its neighbours, which reflects the trust it puts in them. Based on that...
Wireless Mesh Networks are a wireless multi-hop networks in which the nodes are characterized by theirs stability. In this sort of network the minimum cost tree connects sources and receivers by implying a minimum number of forwarding nodes. This paper introduces an adaptation to the popular multicast protocol ODMRP (On-Demand Multicast Routing Protocol) named OODMRP (Optimized On-Demand Multicast...
A managed wireless mesh for infrastructure-level, stable regional mesh network has been studied. NerveNet, which we have been proposing, is a concept of future regional platform network that covers local regions and provides various context-aware services with the shared use of sensors and actuators. The managed wireless mesh developed for materializing NerveNet features auto-configuration of multiple,...
Wireless mesh networks (WMN), with static wireless back-bone and multi-hop communication, as protocols typically employed in WMN are, for the most part, not designed for real-time communications. WMNs experimentation is subjected to stochastic factors such as channel contention, interference, node mobility and access latency add delay and degrade the quality of the stream, pose new design challenges...
Wireless Mesh Network is mainly used to obtain Internet access, so most of the traffic converges to gateways. Due to the nature characteristic of WMN traffic model, gateways unavoidably become the bottleneck of the whole network. An anycast-based gateway selection model was proposed in this paper to solve the gateway selection problem. In this model, all the gateway nodes were abstracted as an anycast...
This paper presents a new metric for routing in wireless mesh networks (WMNs). The proposed metric does not only consider the quality of wireless links to choose a high throughput path between a pair of nodes, but it also includes the resulting interference introduced by using such links. The philosophy behind this metric is to choose a good path for an arriving connection, not necessarily the best...
For tactical networks, rapid reconfiguration and recovery of network topology is highly required. In this paper, we propose an effective tactical network architecture with WMN(Wireless Mesh Network)-based backbone. To reduce the computational and maintenance complexities of tactical networks, a hierarchical architecture is considered in the proposed architecture. The proposed architecture is called...
