Abstract
In this paper, we discuss the access control in multimedia CDMA ALOHA proto col. We introduce a new algorithm for the access control based on Modified Channel Load Sensing Protocol (MCLSP) in an integrated Voice and two differ ent classes of data users, high bit rate and low bit rate, exist in a multi -code CDMA Slotted ALOHA system. With our new algorithm, we show that the t hroughput of high bit rate data users, as well as, the total throughput of the data medium can be optimized and take a maximum value even at high valu es of offered loads. We also investigate the performance when voice activit y detection (VAD) is considered in voice transmission.
