In recent years a new type of wireless networks named wireless mesh networks has drawn the attention of researchers. In order to increase the capacity of mesh network, nodes are equipped with multiple radios tuned on multiple channels emerging multi radio multi channel wireless mesh networks. Therefore, the main challenge of these networks is how to properly assign the channels to the radios. O...

We address the problem of congestion control in multi-radio, multi-channel, wireless mesh networks. Compared to its single radio counterpart for which solutions exist, this problem is significantly more complex because it requires the radio channel assignments and the traffic allocations per channel be jointly optimized. We address the problem by introducing a formulation that allows its decomp...

Employing multiple channels in wireless multihop networks is regarded as an effective approach to increasing network capacity. This paper presents a centralized quasi-static channel assignment for multi-radio multi-channel Wireless Mesh Networks (WMNs). The proposed channel assignment can efficiently utilize multiple channels with only 2 radios equipped on each mesh router. In the scheme, the n...

The first result concerns whether the capacity of a static multi-channel multi-radio wireless network is equal to the sum of the capacities of the corresponding single-channel singleradio wireless networks. For the Arbitrary Network model, the former in general is not equal to the latter, i.e., the network capacity is not separable in channels. However, if the number of radio interfaces at each...

Providing Quality of Service (QoS) is a major challenge in wireless networks. In this paper we propose a distributed call admission control protocol (DCAC) to do both bandwidth and delay guaranteed call admission for multihop wireless mesh backbone networks, by exploiting the multi-channel multi-radio (mc-mr) feature. We propose a novel routing metric for route setup, and present an efficient d...

In order to solve the limited energy and low throughput problems of the battery-powered wireless mesh network (WMN), an IEEE 802.11n based multi-radio multi-channel energy balancing and high throughput protocol (EBHT) for battery-powered emergency WMN is presented in this paper. EBHT optimizes the route path planning to achieve the energy balance by taking WMN nodes’ residual energy, client acc...

This paper addresses Quality-of-Service (QoS) improvement in wireless mesh networks (WMNs) with multi-radio multi-channel by applying a novel network coding technique. It is known that network coding over wired networks enables connections at rates that cannot be achieved by traditional routings. However, the properties of wireless networks (e.g., omnidirectional transmissions, destructive inte...
