| Abstract: |
| According to the characteristics of high delay and loss ra
te in Delay Tolerant Networks (DTNs), an adaptive error control scheme based on
packet loss rate on MAC layer is proposed. The proposed scheme improves the perf
ormance of the transmission control layer and MAC layer. The simulation results
indicate that the scheme can improve the network transmission latency of DTN, an
d meet the requirements of latency sensitive services. |
