We model the multi-path routing with selfish nodes as an auction and provide a novel solution from the game-theoretical perspective. By adapting the idea of generalized second price (GSP) payment originating from Internet advertising business and developing pertinent policies for multi-hop networks, we design a mechanism that results in Nash equilibria rather than the traditional strategyproofness,...
A wireless mesh network (WMN) is expected to be a key enabler for next generation networking due to its infrastructure-less strengths such as scalability, costefficient rapid deployment, and long distance communications. To boost the strength of WMNs, it is required to balance loads among multiple gateways as well as mesh nodes. However, there have been only few practical and easily-implementable...
Wireless Mesh Networks (WMNs) provide a cost-effective way of deploying a network and providing broadband Internet access. In WMNs a subset of nodes called gateways provide connectivity to the wired infrastructure (typically the Internet). Because traffic volume of WMNs is expected to be high, and due to limited wireless link capacity, gateways are likely to become a potential bottleneck. In this...
Wireless mesh networks will play an important role in the next-generation wireless communication systems as it can provide wide coverage and scalable broadband Internet access services. However, congestion in such networks may lead to throughput degradation, packet loss and longer transmission delay. Therefore, routing and traffic forwarding schemes which are aware of the congestion status of a wireless...
The demand for wireless networks which provide high bandwidth and access to the Internet continues. In recent years, a new class of networks which fulfill these requirements evolved, wireless mesh networks (WMNs). Although WMNs satisfy the demand for high bandwidth and Internet access, there is a further, fundamental factor of success: the simple use. Except for small networks, manual configuration...
IEEE P1900.4 is an emerging standard for optimized radio resource utilization where cognitive radio technologies are used for efficient spectrum utilization. In this paper, we design and implement a cognitive wireless network system based on open documents of IEEE P1900.4, and evaluate its performance using UDP streaming and HTTP download. Our experiments show interesting results that total network...
Opportunistic routing (OR) schemes, such as ExOR, have been shown to provide significant throughput gains over traditional best-path routing schemes for wireless networks. Though the performance of OR schemes depend on the bit-rate, they currently use a fixed rate for transmitting packets. While several schemes have been proposed for selecting bit-rate for unicast transmission to a single receiver,...
