In order for improvement of route detection probability of wireless multi-hop message transmission in mobile ad-hoc networks, it is reasonable to make multi-hop message transmission routes with uni-directional links available. Different from in bi-directional links, it is impossilble to adapt backward error correction (BEC) mechanism with acknowledgment messages, timers and message retransmission in uni-directional links. This paper discusses forward error correction (FEC) mechanism in unreliable wireless transmission links. Here, multiple copies of each data message are transmitted. The number of the copies are predetermined and all the copies are transmitted independent of results of transmission of previous copies.
By comparison of performance of these error correction mechanisms, for achieving the same message transmission ratio, FEC consumes less wireless
transmission resources than BEC especially in unreliable wireless transmission enveronment if the number of copies of messages is relatively small. On the other hand, if the number of copies of messages is relatively large, message transmission ratio in FEC is lower than in BEC with the same wireless transmission resources; however, the difference is negligible. Hence, data message transmission through uni-directional links with FEC is useful for higher connectivity and higher reliablility in mobile ad-hoc networks. |
