Wireless Mesh Network technology refers to technology that establishes a wireless network whose transmission speed is similar to that of a wired system. It provides enhanced flexibility in the building of the network, compared to the existing wired network. In addition, it has lower mobility and less restriction from the energy effect. However, there are many considerations, such as system overhead,...
Wireless mesh networks (WMNs) are developing as a potential solution for growing wireless applications. As the area is new, there are many basic issues still to be solved. This article investigates applicability of the ad-hoc routing protocols and the suitability of existing routing metrics for WMNs. AODV is enhanced by proposing a new hybrid routing metric. The results show that selected path is...
We present a multiple-metric approach in order to improve routing in wireless mesh networks (WMNs). It is based on the proactive optimized link state routing (OLSR) protocol to deal with applications with high quality of service (QoS) demands. Since routing with multiple metrics is an NP-complete problem, we use the analytic hierarchy process (AHP) and pruning techniques to perform such routing. The...
In expanded service area of wireless mesh network to support mobility of the mobile station research is recognized as an important issue. Due to the mobile station move frequently to changing the path, data loss and network performance degradation are often occur, such as the service broken. In the existing research of support mobility, the Layer 3 or mobility is required, but it may cause the backup...
With the spread of small wireless devices, mobile mesh networks (MMN) will be constructed in the near future by interconnecting such devices. However, it is difficult to reliably deliver data over the moving nodes in an MMN due to the instability of the wireless medium and the movement itself of mobile nodes. Although an existing method, MORE, improves the efficiency of data delivery in fixed wireless...
In this paper, we consider the problem of topology control by joint power control and routing to maximize the network throughput in wireless mesh networks. First, we present two mathematical formulations of the joint power control and routing problem according to two different definitions of network throughput: the total throughput and the minimal per-node throughput. To reduce the computation cost,...
The routing problem in wireless mesh networks is concerned with finding "good" source-destination paths. It generally faces multiple objectives to be optimized, such as i) path capacity, which accounts for the bits per second that can be sent along the path connecting the source to the destination node, and ii) end-to-end delay. This paper presents the mesh routing algorithm (MRA), a dynamic...
