| Summary: | To address the problem of detection accuracy affected by situations like the omission of node receiving wrong frame and failure of monitoring beyond nodes'communication range during the consideration of the ex ing selfish node detection algorithms in opportunistic networks,a novel and reliable selfish node detection algorithm——RSND algorithm for opportunistic networks was proposed.It employs wrong frame analysis based on cross-layer monitoring mechanism,information excavation based on node encounter and node distance estimation based on RSSI three new mechanisms to eliminate the influence of node's selfishness detection due to wrong frame and failure of monitoring beyond nodes' communication range,improving the reliability of detection.Theoretical analysis verifies the effectiveness of RSND,and simulation results show that RSND can improve selfish node detection accuracy ratio and network throughput at least 6% and 4%,as compared to the existing selfish node detection algorithm based on 2-ACK and watchdog detection algorithm. |
