Abstract
This paper presents the study of a multi-hop packet radio network with spatial randomly located stations using the S-ALOHA protocol. We evaluate the one-hop throughput for the case of different transmission probabilities for newly generated and previously collided packets. It is shown that the impact of the retransmission probability on throughput is comparable for fully-connected and multi-hop networks. Our main interest, however, is the evaluation of the mean backlog-time of a packet, i.e. the mean number of slots between the first transmission attempt and the successful transmission of a packet. We show that multi-hop networks have better stability properties than fully-connected networks because the number of users who can interfere with each other is very small. Further, the influence of the station’s mobility on the mean backlog-time is treated.
