This paper proposes Complex Routing for temporary information sharing in a wireless mesh network built in a geographically limited area. Complex Routing determines a route from a sender to a receiver based on the operations of the complex numbers held by each node. In addition, it provides an adaptation mechanism for changing the complex numbers. In temporary information sharing, senders and receivers...
This paper studies the problem of multicast routing and channel assignment in multi-channel and multi-interface wireless mesh networks. The advantage of the wireless broadcast's nature is used to reduce interference and improve network throughput. The employed network model is first described. Next, a heuristic channel assignment algorithm that makes use of the wireless broadcast's advantage is presented...
The availability of cost-effective wireless network interface cards has recently made it possible to equip wireless mesh routers with multiple interfaces. The problem how to assign channels to those interfaces has been consequently studied and shown to be strictly related to the routing problem. In a previous work, we have proposed a Layer-2.5 forwarding paradigm for multi-radio wireless mesh networks...
With the spread of small wireless devices, mobile mesh networks (MMN) will be constructed in the near future by interconnecting such devices. However, it is difficult to reliably deliver data over the moving nodes in an MMN due to the instability of the wireless medium and the movement itself of mobile nodes. Although an existing method, MORE, improves the efficiency of data delivery in fixed wireless...
Current works on the joint routing and channel assignment (JRC) problem in wireless mesh networks (WMNs) assume that all links operate at the base rate. In other words, they do not consider the presence of multiple bit-rates. However, in multi-rate WMNs, the achievable throughput of a link operating at higher rates could be much less than its bit-rate when it has to contend with low-rate links. This...
In wireless mesh networks (WMNs), to provide Internet connection, packets originating from mesh clients are relayed through multihops by the mesh routers (MRs) towards the Internet gateway (IGW). As MRs may belong to different entities, in the aim to provide sufficient Internet throughput to its clients or avoid traffic congestion, a selfish MR fully or partially drops the relay packets oriented towards...
Wireless mesh networks, mobile ad-hoc networks and wireless sensor networks are some of the names related to a more general concept that can be described as wireless multihop networks. The topic of the tutorial is motivated for the feeling of lack of connection between reality and theory in the study of this kind of networks. The tutorial starts with an introduction to some applications and the technologies...
