Abstract

Abstract: The design and performance of a multi-channel M AC protocol for voice / data integrated traffic over IEEE 802. 11 mobile ad-hoc networks are presented. The proposed protocol is based on CSMA /CA basis. The dynamic channel selection scheme is implemented and the number of the data channel is independent of the network topology. The priority for realtime traffic is assured by improving back off arithmetic and different IFS.

Key words: wireless communication, multi-hop wireless ad hoc networks, medium access control
