A Wireless Mesh Network (WMN) is connected by multiple wireless mesh routers that are able to operate multiple channels for increased network capacity. As other wireless networks, the network capacity is a fundamental issue in the WMN. The analytical results in this paper show that the upper bound of network capacity lambda scales Theta(Wf/cradicn) if the number of infrastructure nodes m is significantly...
The network performance such as node capacity in a wireless mesh network (WMN) could be limited due to inappropriate interface configuration. Mesh routers (MRs) with heavy load may suffer from interface shortage. On the other hand, a MR with less load experiences a low utilization of interfaces. In this paper, we advocate heterogeneous interface configuration to appropriately configure the MRs' interfaces...
A wireless mesh network is a wired extension of a multihop ad hoc network that defines a new paradigm for broadband wireless Internet access. A packet originating from a mesh client is relayed collaboratively in a multihop fashion by the intermediate mesh routers toward an Internet gateway. All existing mesh routing protocols assume that each MR honestly participates in packet forwarding. This is...
The placement of mesh routers (MRs) in building a wireless mesh network (WMN) is the first step to ensure the desired network performance. Given a network domain, the fundamental issue in placing MRs is to find the minimal configuration of MRs so as to satisfy the network coverage, connectivity, and Internet traffic demand. In this paper, the problem is addressed under a constraint network model in...
Unlike ad hoc networks where traffic is randomly distributed among every pair of nodes, the traffic in wireless mesh networks (WMNs) is predominantly toward or from the Internet Gateways (IGWs)for Internet services. Due to this, interference and collision are more serious in the Mesh Router (MRs) closer to the IGWs and the Internet throughput of the network is limited by the number of orthogonal channels...
This paper proposes a new heterogeneous multi-hop cellular IP (MCIP) network that integrates multi-hop communication with cellular IP. MCIP increases the coverage of the wireless network and improves the network robustness against adverse propagation phenomena by supporting communication in dead zones and areas with poor radio coverage. MCIP includes three components: location management, connection...
