We evaluate the performances of spread spectrum ALOHA protocols, denoted as S_CDMA_ALOHA (slotted CDMA ALOHA) and MS_CDMA_ALOHA (mini slotted ALOHA ) in this paper, for the wireless Data network. Analytic model is presented to evaluate the performance of MS-CDMA-ALOHA system using three dimensional Markov chain. Simulations are also performed with various system parameters. (Number of PN codes, Number of Receivers) Numerical Results show the improved performance can be obtained with MS_CDMA_ALOHA protocol. Also we present simulation results of throughput and delay taking into account receiver complexities.
