Establishing measurement-based reliable path in mobile ad hoc networks

摘要

Due to unpredictable topology change and frequent link failure, it is becoming evidently a major challenge to provide a stable route between source and destination in mobile ad hoc networks (MANET). Unlike previous multipath routing schemes for redundancy and unicast routing protocol utilizing longest route expiration time supported by GPS, we develop a framework to establish the most stable route based on measured frequency of link failure, and available battery, as well as the number of actual connections. To evaluate the performance of the proposed scheme, we also provide practical simulation results with multipath routing and unicast routing protocol in terms of packet delivery ratio, control overhead, and hop counts, as well as end-to-end delay. Through analysis of simulation results, we demonstrate that our scheme shows better performance than the general unicast routing protocol as well as similar packet delivery ratio to the multipath routing protocol with less maintenance overhead.
