Increase in popularity of wireless technology and continuous technological advancement has made ad-hoc network as an area of interest.An ad-hoc network is an infrastructure-less, dynamic wireless network consisted of nodes that can communicate directly with each other if lying in each other vicinity .Because of the dynamic nature, nodes are free to move and arrange themselves arbitrarily. Thus, the network's topology may change rapidly and unpredictably. Existing work in ad-hoc routing is generally related to the better utilization of bandwidth only. But in order to cater all type of real time applications, efficient routing is not a solution. Because of the dynamic nature, routing in ad-hoc networks experiences link failure. Hence, a routing protocol that supports efficient routing along with guaranteed services like guaranteed bandwidth, less delay, reduction in resource consumption, increased throughput etc. (collectively known as Quality of Service or QoS ) is required. This Book provides a new solution for the provision of QoS in terms of Bandwidth and Delay in ad-hoc environment.
