A wireless ad-hoc network is a collection of nodes which are self-


configuring, connected by wireless links. The nodes are free to move randomly and


organize themselves arbitrarily; thus, the network's topology may change rapidly and


unpredictably. These kinds of networks are very flexible and they do not require any


existing infrastructure. Therefore, ad-hoc wireless networks are suitable for temporary


communication links. The biggest challenge in these kinds of networks is to find a path


between the communication end points of nodes that are mobile. Due to the limited


transmission range of wireless interfaces, the communication traffic has to be relayed


over several intermediate nodes to enable the communication between two nodes.


Therefore, these kinds of networks are also called multi-hop ad-hoc networks. The


proposed model is designed to improve the problems of real-time event-based


communication. It improves the packet delivery ratio by prior prediction and reduces


end-to-end packet delay. This in turn improves performance of the routing process


significantly and increases the Quality of Service (QoS).
