Abstract:

Most previous work on real-time event-based communication has assumed infrastructure-based networks. An Ad-Hoc network is a (possibly mobile) collection of communications devices (nodes) that wish to communicate, but have no fixed infrastructure available, and have no predetermined organization of available links. Individual nodes are responsible for dynamically discovering which other nodes they can directly communicate with. Ad-Hoc networks can be built around any wireless technology, including infrared and radio frequency (RF). Routing in wireless Ad-Hoc networks has received significant attention from recent literature due to the fact that dynamic behaviour of these networks poses many technical challenges on the design of effective routing schemes. We present Dynamic Source Routing (DSR) and Node Failure Prediction QoS Routing (NFPQR) algorithms for wireless Ad-Hoc networks. Though DSR algorithm is shown to perform well, it does not take into account the power conditions of a node due to which node failure may occur. Hence a new routing algorithm called Node Failure Prediction QoS Routing (NFPQR) protocol is proposed, which improves the different QoS parameters such as end-to-end packet delay and the packet loss along the path. The algorithm NFPQR predicts the future state of a node to decide whether the node is a good selection as a router or not. A simulation study is performed to demonstrate the effectiveness of the protocol NFPQR, particularly the fact that it achieves a higher rate of successful packet delivery than existing methods.
