....transmission. The performance of reservation and pre allocation random access protocols were compared in [7] where it was shown that pre allocation protocols achieve a significant improvement in performance with reduced system complexity. A hybrid protocol, denoted as DT WDMA, was proposed in [10] that has data channels pre allocated for data packet transmission and a time multiplexed control channel used to inform a destination node of the intentions of a source node. Each node has two fixed (or slow tunable) transmitters and two receivers. One transmitter is parked on the control channel ....

Media access control protocols developed for this environment may be broadly classified into control channel based, and non control channel based protocols [8, 4] Control channel based approaches [3, 6, 7] partition the channels into control and data. Typically, the system has one control channel. The remaining channels (denoted as data channels) are used for data packet transmission. The control channel is used to transmit control information and reserve access to the data channels. Non control ....

The protocols have reduced complexity due to the following reasons: i) simpler architecture single transmitter, and tunable receivers are not required; ii) decentralized protocols where arbitration algorithms do not need to be executed either at slot or cycle boundaries as in [23]; iii) status information to be maintained at each node is negligible; iv) reordering buffers are not required at the transmitting and receiving ends; and (v) the inter dependence between number of nodes, channels and packet size is eliminated.
