Summary:
Backoff-based opportunistic routing can adaptively select a forwarder among receivers based on a random backoff time. However, it cannot correctly work in an environment with asymmetric links where the communication quality differs in the directions. To solve this problem, a confirmation method for link symmetry and destination reachability was previously proposed. However, the method can only confirm link symmetry with one neighbor and destination reachability for a single terminal in a single packet transmission. This paper proposes a fast confirmation method to verify the link symmetry of multiple terminals in single packet transmissions. The performance of the proposed method is clarified with simulations.
