Efficient Packet Delivery Approach for Ad-Hoc Wireless Networks

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).
