Abstract :
As a conventional MAC control protocol for wireless networks, IEEE 802.11 DCF hasn´t taken account into the requirement, which TCP/UDP hybrid stream access needs for MAC frame length. The TCP/UDP hybrid stream´s transmission delay would increase significantly, that always generate failure of TCP stream transmitting. This paper proposes an improved IEEE 802.11 DCF protocol and theory model based on TCP/UDP hybrid streams. The improved protocol mentioned differentiates length between TCP package and UDP package, and adaptively adjusts MAC frame length, which avoids lost packages retransmission and delay from TCP/UDP hybrid stream. The simulation we made to verify that prior estimate for TCP/UDP packages quantities in sole channel can promote throughput of network more than 10% with transmission delay elimination.
