A new structure for packet-radio networks, called the multi-station network, is suggested and analyzed. We describe the salient features of this structure that consists of a large number of nodes and several stations. We then focus on one of the main problems within the suggested structure, the problem of forwarding packets from the nodes to the stations through a shared radio channel. Two basic forwarding schemes are investigated and compared. The classical slotted ALOHA is considered as an access scheme to the shared channel. © 1988.
