Abstract
Previous works on the throughput analysis of the direct sequence-code division multiple access/unslotted ALOHA radio network all used the Poisson arrival process (PAP). However, the interarrival times of PAP are independent, so it is not suited to model today's Internet and multimedia traffic, which have correlated interarrival times. We are motivated to use the Markovian arrival process (MAP), a more general input traffic model that captures the correlation of interarrival times. We are the first to analyze the throughput of the direct sequence-code division multiple access/unslotted ALOHA radio network with MAP. We propose the use of MAP, which encompasses the PAP as a special case. The new MAP model basically generalizes the current traffic and queuing models of multimedia in wireless networks.
