A novel power control algorithm and MAC protocol for CDMA-based mobile ad hoc network
A single busy tone code-division-multiple-access (SBT-CDMA) protocol for mobile ad hoc network (MANET) is proposed. The RTS/CTS handshake mechanism, busy tone and power control are integrated with CDMA to improve the network performance. The RTS/CTS dialogue is used for the CDMA-code allocation and exchange of the power control information. Based on the difference between the calculation value and measurement value of the received busy tone power, a node can ascertain whether could initialize a RTS packet transmission. Based on the estimation of the channel gain, the transmission power of a data packet sender can be controlled exactly not only to improve the anti-MAI (multiple access interference) ability of the desired receiver, but also to reduce the interference on the undesired receivers around the sender. Simulation results show that SBT-CDMA can significantly reduce the packet collision and increase the channel utilization with lower energy consumption
