Abstract

In this paper packet acquisition performances of both slotted spread ALOHA and spread ALOHA multiple-access schemes are examined and compared. The probability of packet acquisition of both schemes are measured as users compete to gain access to the network hub receiver in the presence of additive white Gaussian noise (AWGN) and narrowband interference. Moreover, channel load sensing protocol (CLSP) is employed at the receiver hub in order to improve packet acquisition performance. Results clearly show that the slotted spread ALOHA scheme outperforms spread ALOHA in terms of the probability of packet acquisition. It is also shown that this probability may be improved further by employing the CLSP at the receiver hub.
