In wireless mesh networks, when a packet is relayed by a station, it can get into collision with another packet of the same flow. This effect is called intra-flow interference. In this paper we propose an analytical model to study the problem of intra-flow interference. Taking into account collisions caused by both neighbor stations and hidden stations, we estimate the saturated throughput of a...

Opportunistic Routing (OR) has been proposed to improve the efficiency of unicast protocols in wireless networks. In contrast to traditional routing, instead of preselecting a single specific node to be the next-hop forwarder, an ordered set of nodes (referred to as candidates) is selected as the next-hop potential forwarders. In this paper, we propose a new multicast routing protocol based on ...

According to the IEEE 802.11s draft standard, the mesh STA may maintain proxy information on STAs that are associated with a collocated access point or are behind a collocated portal. The proxy information plays a very important role in wireless mesh networks for additional delays may be introduced owing to the absence of proxy information during frame forwarding. While the method for maintaini...

In this paper we introduce and study a new problem named min-max edge q-coloring which is motivated by applications in wireless mesh networks. The input of the problem consists of an undirected graph and an integer q. The goal is to color the edges of the graph with as many colors as possible such that: (a) any vertex is incident to at most q different colors, and (b) the maximum size of a colo...

Analytical models exist for evaluating gossip-based information propagation. Up to now these models were developed only for fully connected networks. We provide analytical models for information propagation of a push-pull gossiping protocol in a wireless mesh network. The underlying topology is abstracted away by assuming that the wireless nodes are uniformly deployed. We compare our models wit...

Periodic scheduling has many attractions for wireless telecommunications. It offers energy saving where equipment can be turned off between transmissions, and high-quality reception through the elimination of jitter, caused by irregularity of reception. However, perfect periodic schedules, in which each (of n) client is serviced at regular, prespecified intervals, are notoriously difficult to c...

Wireless mesh networks (WMNs) have shown high potential to extend the coverage of high bandwidth infrastructure networks. We propose a deployment of a WMN for the needs of higher education institutes. In order to provide extended coverage to campus networks, several open issues such as authentication and authorisation of connected nodes, accounting of network usage and auditing of the network, ...

A video data sampling and transmission system is designed for video monitoring based on wireless mesh network. Discussion is made on the use of standards, working frequency, network infrastructure, coverage solutions, link budget, frequency planning, power supply, supporting transmission and AC design. Overall solution on wireless Mesh network digital video system is proposed and it is applied ...

Wireless mesh network is the key technology for present generation in wireless networking for providing fast and hassle free services to users. The conformity of Wireless Mesh Networks to offer Internet connectivity is becoming a popular choice for Wireless Internet Service Providers, as it allows a flexible, easy and inexpensive network deployment. However, these networks are prone to critical...
