A Mobile Ad hoc Network (MANET) is a heterogeneous network; a collection of mobile wireless devices with different characteristics communicating in a random network topology. Much research over-simplifies by assuming that all nodes are homogeneous, i.e., possess identical transmission power, reception quality and signal to noise ratio, which is not realistic. Such conditions are ideal and not often...
Wireless mesh networks (WMN); have been attracting an increasingly intensive research over the last few years. WMNs consist of end clients and mesh routers, communicate wirelessly in a multi-hop fashion. The commonly used routing protocols depend on the hop-count metric to determine the preferred route between source and destination. Due to the unpredictable behavior of the wireless medium, the need...
In current multi-hop wireless networks, the routing protocol typically choose the path with the hop count metric. Hop count metric tends to include longer distance link with bad link quality, which then affects the average throughput. In this paper we propose a link-quality aware routing metric for multi-hop wireless networks. This new routing metric simultaneously considers the hop count and the...
In ad hoc networks, any concurrent transmission will add to the level of interference and collision experienced by other users. The spatial density of transmissions that could be supported subject to two constraints: the excessive interference of attempted receivers, the channel access collision of attempted transmitters. We combine two constraint factors and define channel interference and access...
Despite the many routing protocols to choose from in the existing wireless network literature, routing has remained a challenging problem in the actual deployment of wireless mesh and ad hoc networks. To address some of the issues involved with routing in wireless mesh networks, in this paper we attempt to make routing more sensitive to the dynamics of the network such as interference, traffic load...
Enabling transmission over ad-hoc networks is more challenging than over conventional mobile networks because a connection path in an ad-hoc network is highly error-prone and the path can go down frequently. Although it is well-known that wireless channels are time varying because of user mobility and multi-path propagation effects, experiments for various types of channels show that the basic channel...
In this paper, we address the issue of transmission power control (TPC) in wireless ad hoc networks. Power control plays an important role in energy saving and network performance enhancement. However, the existing TPC schemes either face the problem of hidden and exposed terminal or have additional hardware requirements. We propose a novel distributed power control protocol, called Receiver Initiated...
