A topology transparent link activation protocol for mobile CDMA radio networks

摘要

A topology transparent protocol for link activation in mobile CDMA networks is presented. The protocol resolves primary and secondary conflicts, and can easily be adapted to TDMA link activation, as well. The proposed protocol guarantees that each link will be successfully activated at least once in a frame without the need to adjust transmission schedules in mobile environments. Compared to other protocols with guaranteed delivery, the overhead due to the recomputation of transmission schedules is eliminated and, accordingly, transmissions need not be suspended for schedule reorganization. Furthermore, contrary to previously known protocols that adapt to mobility by schedule recomputation, the proposed solution is not subject to a potential catastrophic failure when the rate of topology changes exceeds the rate at which schedules can be readjusted. We prove the correctness and evaluate the efficiency of the new protocol by analytical methods.
