Abstract:

By integrating the bytes interleaving technology based on FEC and ARQ, and introducing a simple shaking- and-response UDP protocol, this paper presents a new hybrid error control scheme for wireless networks and evaluates its performance by conducting a mathematical analysis carefully. Experiments show that the success ratio of data transportation will get as much as 96% and even higher by adopting parameters elaborately in wireless networks when res idual BER is very high. Thus, this scheme can meet the requirements of data transoortation in tough wireless environments.
