Abstract:
Since the communication is based on the received power of the forwarding node, it is possible to measure the quality of the route and we can estimate the status of the link. When a node does not have enough received signal strength, then it believes that the link will break within a short period of time Based on this identified factor, we propose an Adaptive Reliable Routing protocol for ad hoc networks. In this protocol, whenever a link is likely to be broken the link failure can be determined by examining the received signal strength. When a link is likely to be broken, the previous node will cache the subsequent packets in its data buffer. When a link failure occurs, the upstream node with the cached data in its buffer can retransmit it through the next reliable link. By simulation results, we show that the proposed reliable routing protocol achieves high delivery ratio with reduced delay and overhead.
