In this paper we design, implement and evaluate a practical flow-based routing architecture for WMNs, called TALB, which exploits traffic measurements to balance traffic load over available mesh paths and gateways. To achieve throughput enhancements while mitigating inter-flow interference, TALB implements a \emph{Constrained Maximal Bottleneck Path} computation algorithm to maximize the bottleneck...
Most studies on WMNs have assumed that all network traffic from clients goes through a gateway node. However, point-to-point traffic is expected to significantly contribute to WMN network load in many scenarios. In this paper we propose a novel routing strategy that seeks to alleviate network congestion by avoiding paths that are already heavily loaded. Our scheme effectively takes into account the...
There is a vast literature on the performance modeling of the 802.11 MAC protocol, but the interplay between the TCP dynamics and the self-regulating behavior of the 802.11 CSMA/CA access method has not been sufficiently investigated. In addition, it has been observed that TCP stations in a WLAN are sporadically active due to the TCP flow control mechanisms. This makes traditional saturated models...
In the last years, the number of Wi-Fi hotspots at public venues has undergone a substantial growth, promoting the WLAN technologies as the ubiquitous solution to provide high-speed wireless connectivity in public areas. However, the adoption of a random access CSMA-based paradigm for the 802.11 MAC protocol makes difficult to ensure high throughput and a fair allocation of radio resources in 802...
