Reasonable channel assignment is one of the key research contents of the multi-channel assignment algorithms. A distributed channel assignment method based on partition of interface function was proposed in this paper. Different channel assigning or switching algorithms for interfaces with different function were used: Channel assigning algorithm based on measuring time to gateway was used for station...
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,...
A Link Level Load-Aware Queue Scheduling algorithm (LLLAQS) on MAC layer is proposed in this paper in order to suppress the data transmission on congested links and balance the load in the wireless mesh networks. The algorithm not only takes the load on the congested node into consideration but also differentiates the congested links and non-congested links. By scheduling the traffic on the non-congested...
In wireless mesh networks (WMN), most flows are destinated to Internet. The IEEE 802.11s standard does not consider the flow characterization of WMN. Employing the mechanism may cause some scalable issues. SWMN, a new scalable architecture for WMN is proposed, which consists two components, one is mesh backbone, the other is mesh domain. To form this architecture, two metrics "radio metric"...
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...
