摘要
In tactical scenarios, the dual-channel networking scheme designed for a certain type radio can solve the serious waste of code resource significantly, which is caused by the traditional code networking scheme. The random packet CDMA technology is used to enhance the anti-jamming capability of control channel of dual-channel networks, and a new MAC protocol, called carrier sense random packet CDMA, is proposed. A performance analytical model of slotted spread spectrum ad hoc networks based on CSRP-CDMA is established, which provides packet transmission success probability and expressions of network throughput. And the influences of the factors, such as spreading gain, packet header and payload ratio, received signal-noise ratio, on network performance are analyzed. Finally, CSRP-CDMA protocol is compared with the traditional MAC protocol for RP-CDMA by network simulator OPNET. Numerical and simulation results show that CSRP-CDMA protocol has higher network performance than the traditional MAC protocol, and the theoretical normalized network throughput value of CSRP-CDMA can reach 0.75 to guarantee the resource utilization of control channel effectively. © 2015, China Ordnance Society.
