Improving QoS for Ad-Hoc Wireless Networks Using Predictive Preemptive Local Route Repair Strategy

Ad-hoc wireless networks comprise of sets of nodes connected by wireless links that form arbitrary wireless network topologies without the use of any centralized access point. Ad-hoc wireless networks are inherently self-creating, self-organizing and self-administering. The proposed model is designed to alleviate the impediments to real-time event-based communication that are characteristics of an ad-hoc wireless environment, for example, dynamic connectivity, unpredictable latency and link failures and limited resources and it improves the performance of die routing process significantly and increases the Quality of Service (QoS). It can reduce communication overhead (by avoiding unnecessary warning messages), decrease the number of breaks in active links (by prior prediction), reduce end-to-end packet delays, and improve packet delivery ratio (by segmentation of packets).
