Virtual Mobile Backbones for Wireless Ad-hoc Networks with the support of Directional Array Antennas

Ad-hoc network techniques are in the center of attention to many scientists and engineers in the fact that wireless ad-hoc networks will bring high speed communication to the users with no given fixed infrastructure such as the base station or the AP (access point). However, the infrastructure-less topology brings new limitations such as small connectivity of nodes in the network caused by the short communication range of nodes. In this work, to solve these problems we propose the adaptation of directional array antennas in a virtual mobile backbone ad-hoc network. This adaptation can partially solve the complexity problem by activating directional array antennas only at backbone nodes and by performing beamforming techniques it will bring better connectivity of the nodes in the network resulting higher throughput performance
