In this paper, we study the fairness problem for downlink traffic in multi-hop wireless backhaul networks with selfish nodes, including Transit Access Points (TAPs) and the gateway. Unlike the transmission of uplink traffic in which transit packets are dropped at intermediate TAPs, almost all downlink link traffic is dropped at the gateway. Therefore, we design an incentive-based mechanism where the...
IEEE 802.11-based mesh networks can yield a throughput distribution among nodes that is spatially biased, with traffic originating from nodes that directly communicate with the gateway obtaining higher throughput than all other upstream traffic. In particular, if single-hop nodes fully utilize the gateway's resources, all other nodes communicating with the same gateway will attain very little (if...
We have currently reached a phase where big shifts in the network traffic might impose to rethink the design of current architectures, and where new technologies, being pushed into market, will act as enabler of such changes. Taking into account the current scenario and its likely evolution as well, in this paper we examine the case for multi-path routing within the metropolitan access network. Through...
Wireless Mesh Networks (WMNs) support the cost-effective broadband access for Internet users. Although today's IEEE 802.11 PHY and MAC specifications provide multi-channel and multi-rate capabilities, exploiting available channels and data rates is a critical issue to guarantee high network performance. In multi-rate wireless networks, high-rate links heavily suffer from performance degradation due...
