Wireless mesh networks usually deploy multiple gateways to enhance the capacity. This paper studies how to maintain forwarding paths in 802.11s wireless mesh network. A Multi-Gateway Multipath routing protocol (MGMP) is proposed to explore path diversity. MGMP constructs multiple paths between source and destination using a proactive tree architecture as HWMP. In order to make MGMP more efficient,...
Due to unstable link states, broadcasting transmission pattern, and interference between neighbor nodes, routing in wireless mesh network (WMN) is much more complicated and unpredictable than wired network. As the simplest and most primitive routing metric, hop count does not always work well in WMN where routing with least hop count does not bring the best performance. Recent research shows that...
Compared with other routing metrics, such as RTT, PktPair, ETT has become the tendency for routing selecting in wireless mesh networks (WMNs). However, in ETT, the node quality is not considered. In this paper, the time during which the packet cached in the relay node is defined as node quality, while this caching time is for the node contending for the channel successfully to transmit it. To calculate...
Energy efficiency has been known as the most important problem in designing a data query system in wireless sensor networks (WSNs). In this paper, we propose a novel query method in which the clusters are constructed only in the query area as needed and destroyed after the query ends. To achieve this goal, we design and implement a Tree-Based Clustering (TBC) protocol to support upper layer applications...
Different to conventional wireless multi-hop networks, the router is fixed and mobility is not the main problem in wireless mesh networks (WMNs). So a new metric is required imminently to fit in with the situation. Multi-radio and multi-channel are used in WMNs to enhance network capacity. WCETT is a metric designed for multi-radio and multi-channel wireless mesh network, but the bandwidth computation...
