This paper proposes a MAC-layer timeslot allocation signaling protocol for IEEE 802.16d mesh networks. The proposed mechanism complements the three-way-handshake signaling described in the specification to achieve fair sharing of timeslots among nodes and flows. In this paper, the authors study the case where timeslots are reserved until cancelled explicitly. This form of reservation is efficient for long sessions of data transmissions such as video streaming or interactive media applications. Since timeslots are exclusively reserved for individual flows, bandwidth starvation can occur if remaining timeslots in the wireless medium around a node are not enough to fulfill new bandwidth requests.
