Abstract :
In this paper, the effect of user cooperation on network performance is investigated in terms of throughput for CDMA random access networks where a large number of users randomly access an access point (AP). The network considered consists of two classes of users depending on the received power at the AP. A cooperation strategy with very low overheads is proposed, and the network performance gain obtained by adopting this strategy is characterized in closed-form formulas. The validity of our analysis is confirmed by simulation results.
