Wireless Mesh Networks (WMNs) is an emerging and latest technology that is used to develop the new attractive applications for wireless network users. WMNs provide a good platform for many researchers to develop new innovative procedures and methods to improve the network performance in wireless enterprise backbone networks. WMNs have unique features like ease of deployment at low cost. By adding...
This paper presents the high level specification of a Self Configuration Framework for 802.11 multi-radio Wireless Mesh Networks based on a centralised topology discovery and channel assignment mechanism. The framework was designed to support the introduction of a new Mesh Node into the network at any time of the network's operational phase. Further, it enables a new Mesh Node to locate and communicate...
Because of existence of the interference, WMNs' end-to-end throughput usually is not very ideal. In order to solve this problem, this paper design an topology algorithm which via combining collision domain load and power control to structure network topology and optimize network throughput. The algorithm adjust each node transmission power to a reasonable leve after construct the network topology,...
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 Network (WMN) is a self-configuring, self-organizing and self-healing communications network in a mesh topology. Every node collaborates on establishing routing path to communicate with each other or use the Internet services. Even though WMN increases reliability and provides high bandwidth, selfish or malicious nodes may disrupt the network-wide collaboration and abuse the available...
Wireless Mesh Network (WMN) is vulnerable to passive monitored attacks because of the specific character of wireless channel. The existing security routing protocols of WMN are all the improved ones based on the original Ad hoc network protocols, so it is necessary to design a new security protocol for the specific character of WMN. In this paper the Onion Ring protocol designed by Lee has been analyzed...
In wireless mesh networks, joint optimization of routing and link scheduling within a time-division multiplexing approach is commonly sought to provide end users with high data rates. However, the strategies proposed to this end usually proceed by means of complex optimization models, which also often rely on oversimplified assumptions, especially for what concerns wireless interference. In the present...
In this paper, we present our design and implementation of load-balanced gateway discovery routing protocol called LBGD-AODV. A gateway node in a wireless mesh network acts as bridge between mesh routers and external network in order to provide services such as broadband. We observed in our SwanMesh testbed that a single gateway can only serve up to a limited number of hops due to noticeable throughput...
Wireless mesh networks (WMNs) have become a better alternative for extending wireless Local Area Networks (WLANs) to provide network coverage up to the furthest of far flung rural areas. This has been implemented by using a meshed backbone network interconnecting the mesh access points (MAPs) that manages each of the WLANs. The routing algorithms use the mesh backbone to establish inter-WLAN routes...
In this paper, we propose an adaptive pacing scheme at the link layer for IEEE 802.11 based multihop wireless networks. Our objective is to improve the performance of higher layer protocols without any modifications to them. Our adaptive pacing scheme estimates the four-hop transmission delay in the network path without incurring any additional overheads, and accordingly paces the packets to reduce...
