–Wireless mesh networks (MMNs) are an emerging technology right now. During their lifetime, multi-hop wireless mesh networks (WMNs) experience frequent link failures caused by channel interference, dynamic obstacles and/or applications bandwidth demands. These failures cause severe performance degradation in WMNs or require expensive, manual network management for their real-time recovery. This...

In multi-radio wireless mesh networks, one node is eligible to transmit packets over multiple channels to different destination nodes simultaneously. This feature of multi-radio wireless mesh network makes high throughput for the network and increase the chance for multi path routing. This is because the multiple channel availability for transmission decreases the probability of the most elegan...

We study oblivious deterministic gossip algorithms for multi-channel radio networks with a malicious adversary. In a multi-channel network, each of the n processes in the system must choose, in each round, one of the c channels of the system on which to participate. Assuming the adversary can disrupt one channel per round, preventing communication on that channel, we establish a tight bound of ...

Shortest link scheduling (SLS) is one of the most fundamental problems in wireless networks. Almost all of the state-of-the-art approximation algorithms for SLS in wireless networks are resorted to the ellipsoid method for linear programming exclusively. However, the ellipsoid method can require an inordinate amount of running time and memory even for a moderate sized input, and consequently is...

Achieving efficient bandwidth utilization in ad-hoc networks is known to be a challenging open research issue. Recently, much attention has been devoted to wireless mesh networks and consequently, it has been renewed the interest in improving the performance of ad-hoc networks, which are used as the backhaul structure of hybrid ad-hoc/cellular systems. Moreover, fairly new concepts such as mult...

Equipping mesh nodes with multiple radios that support multiple wireless channels is considered a promising solution to overcome the capacity limitation of single-radio wireless mesh networks. However, careful and intelligent radio resource management is needed to take full advantage of the extra radios on themesh nodes. Flow-radio assignment and channel assignment procedures should obey the ph...

MIMO (Multi Input Multi Output) wireless communication system is an innovative solution to improve the bandwidth efficiency by exploiting multipath-richness of the propagation environment. The degree of multipath-richness of the channel will determine the capacity gain attainable by MIMO deployment. Therefore, it is very important to have accurate knowledge of the propagation environment/radio ...

Recently, multi-radio mesh technology in wireless networks has been under extensive research. This is because of its potential of overcoming the inherent wireless multi-hop throughput, scalability and latency problems caused by the half-duplex nature of the IEEE 802.11. The concept of deploying multiple radios in wireless network access points (APs) has shown a promising way to enhance the chan...

Wireless mesh networks (WMNs) provide high-speed backbone networks without any wired cable. Many researchers have tried to increase network throughput by using multi-channel and multi-radio interfaces. A multi-radio multi-channel WMN requires channel assignment algorithm to decide the number of channels needed for each link. Since the channel assignment affects routing and interference directly...
