In a network, bridging nodes are those nodes that from a topological perspective, are strategically located between highly connected regions of nodes. Thus, they have high values of the Bridging Centrality (BC) metric. We recently introduced the Localized Bridging Centrality (LBC) metric, which can identify such nodes via distributed computation, yet has an accuracy equal to that of the centralized...
Wireless mesh networks (WMN) are receiving increasing development, which configuration multi-radio multi-channel nodes to improve channel resources utilization in the network topology architecture and achieve increasing efficient on the network throughput. The main goal of channel assignment algorithms in multi-radio multi-channel wireless mesh networks is to minimize the overall interference and...
Compared with cellular networks, wireless mesh networks (WMNs) need more careful design for resource allocation. To this end, we develop a clique-based proportional fair scheduling (CBPFS) algorithm for WMNs. Furthermore, we obtain a closed-form model to quantify the throughput of connection links and traffic flows in multi-hop transmissions. We use the derived analytical framework to estimate the...
This paper presents a bandwidth occupied time proportion fair MAC algorithm (BOTP-FMAC) for WLAN and wireless mesh network (WMN). It aims to address the unfairness problem in enhanced distributed channel access (EDCA) mechanism, in which higher-priority streaming traffic flows intend to severely deprive the access opportunity of lower-priority traffic flows due to the capture effect, especially when...
