摘要
为解决地面网络化弹药MAC协议对弹药网络的功耗和传输时延的重大影响.提出了一种适用于地面网络化弹药的混合型分簇MAC协议.结合基于竞争和分配的协议特点,根据传输时间估计和业务量选择不同的接入方式,避免了碰撞和信道浪费;通过时隙复用降低端到端时延;通过无关节点睡眠降低占空比和网络功耗.仿真表明,与传统的基于竞争机制和基于TDMA机制的协议相比,该协议在吞吐量、端到端时延和功耗等方面均具有较好的性能.
The MAC protocol plays an important role with power consumption and transmission delay in the networked munitions systems. A low power and low delay MAC protocol suitable for land-based networked munitions was presented. Features of competing and distributed based protocols were combined. Combining the features of competing and distributed based protocols, choosing different methods to access channels depend on transmission time and traffic, it could avoid collision and waste of the channel, and reduce the transmission delay with slot reuse. Sleeping unrelated nodes in transmission, it could reduce the power consumption. Simulation shows that this protocol has better performance on throughput, end-to-end delay and power consumption compared with traditional distribution and competing MAC.
