Abstract

Abstract:

To solve the problem of resource efficiency in a wireless network, on the premise that the Quality of Service parameters such as packet loss rate and time delay are guaranteed, the constrained relations among packet loss rate, time delay, packet length, availability and buffer capacity are established. The network multiplexing efficiency determined by packet overhead, adaptation overhead, error correction efficiency and framing efficiency is given. With the error control mechanism, the computing method and procedures of the optimal packet length which makes the best resource efficiency of the wireless network are presented. Simulation results show that the optimal packet length of the wireless network decreases rapidly with the rise of packet loss rate, and that the network resource efficiency decreases as well. This computing method can be used in the flexible network with variable packet lengths for different services.

Key words: wireless network, packet length, resource efficiency, error control, quality of service(QoS)
