A hybrid contention-based TDMA technique for data transmissions
Duei Tsai, J.-F. Chang · IEEE Transactions on Communications · 1988
A hybrid contention-based time-division multiaccess (TDMA) protocol is proposed and studied. Channel time is organized into frames, each consisting of reservation, fixed, and variable subframes. Users are divided into groups. Each group is given a data slot in the fixed subframe that is open to users in that group on the basis of contention. Each user can also place his demand in the reservation subframe. The number of slots assigned to a particular user is based on the information gathered from the other two subframes. Performance analyses, both transient and steady-state, are successfully carried out. Computer simulations verify the analyses.>
