An integrated services MAC protocol for local wireless communications

This paper proposes a medium-access control (MAC) protocol for integrated voice/data services in local wireless communications. The proposed protocol is a hybrid of R-Aloha and Aloha reservation adapted to local wireless environment. In the proposed hybrid Aloha-reservation/R-Aloha (HAR) protocol, data messages are transmitted using Aloha-reservation protocol, whereas voice packets are transmitted according to R-Aloha on the channel assigned using Aloha reservation. The performance of the HAR protocol is analyzed by computer simulation. Simulation results prove that the HAR protocol is appropriate as a protocol for integrated services wireless networks in which computer data is major traffic and voice traffic coexists.
