Abstract : The current cellular system provides a predetermined number of mobile subscribers dedicated telephonic service if they are within transceiver range of its backbone network. The subscriber's mobility is limited to the coverage area of the cell grid and is further bound by the number of dedicated channels available in a cell. This report proposes a mobile computer network wherein the terminals double as relays affording the mobile subscriber greatly mobility and where all terminals share a common transmission channel. The main design issues of the proposed mobile computer network's data link and network layers are investigated. The network incorporates nonpersistent Busy-Tone multiple access channel as the means of linking all stations together. A unique routing algorithm which maximized packet discarding and maps the network topology is described and used. The congestion control techniques incorporated in this network reduce even further the networks blocking probability and relative measure of congestion. Keywords: Theses; Packet radio networks.
