Due to its ability to deliver scalable and fault-tolerant solutions, applications based on the peer-to-peer (P2P) paradigm are used by millions of users on the internet. Recently, wireless mesh networks (WMNs) have attracted a lot of interest from both academia and industry, because of their potential to provide flexible and alternative broadband wireless internet connectivity. However, due to ...

Multi-Radio Multi-Channel (MRMC) WMNs result in power control problems including interference, un-scalable connectivity and energyconsumption. Several previous studies have focused on the single radio wireless configurations while studying power control problems. However, such contributions can not solve the power control problems in MRMC configurations because of the architectural and structur...

Performance on multi-hop networks suffers from limited channel capacity and poor scalability problem as the network size or density increases(Gupta and Kumar, 2000). One way to alleviate this problem is to equip each node with multiple radios. As hardware cost drops, this approach becomes more and more appealing and feasible. By tuning radios into non-interfering channels, the wireless spectrum...

We study coexistence interference that arises between multiple collocated radio interfaces on 802.11 based multi-radio platforms used for mesh networks. We show that such interference can be so severe that it prevents concurrent successful operation of collocated interfaces even when they use channels from widely different frequency bands. We propose the use of antenna polarization to mitigate ...

The European WINNER (Wireless World Initiative New Radio) project is developing a new radio concept for Beyond-3G (B3G) systems. The radio channel plays an important role in the evaluation of transceiver parameters such as modulation, coding, link adaptation, channel equalization, multi-user scheduling, etc., in terms of, e.g., bit-error-rate (BER), system throughput, and outage probability. Du...

The capacity of the conventional wireless mesh network (WMN) with single channel single radio is limited due to cochannel interference. To resolve this capacity limitation problem, multi-channel multi-radio (MCMR) protocols have been proposed. Wireless mesh networks has attractive significant attention towards promising technology. It is becoming a trend for the fourth generation of wireless mo...
