摘　　要：基于有限域上多项式,设计了一类用于支持多类业务移动自组织网络的多信道拓扑透明MAC调度码。推导了这类调度码的最小码长,同时与一类单信道拓扑透明MAC调度码的码长进行对比。研究结果表明,当信道数为H时,这类多信道拓扑透明MAC调度码的码长约为单信道拓扑透明MAC调度码码长的1/H,因此能够利用多信道资源有效地减小码长。另外,在相同的网络参数情形下,这类多信道拓扑透明MAC调度码在码长以及最小保证吞吐量等方面优于扩展的TDMA固定分配方案。A multi-channel topology-transparent MAC scheduling code was proposed for mobile ad hoc network supporting multi-classes of users via polynomials over finite field. The code length was derived and compared with the single-charmel topology-transparent MAC scheduling code. It is shown that when the number of channel is H, the code length of the proposed multi-channel topology-transparent MAC scheduling code is approximately H times smaller than the code length of single-channel topology-transparent MAC scheduling code. Thus the proposed code can reduce the code length by using multi-channels resources. Moreover, under the same network parameters, the proposed multi-channel topology-transparent MAC scheduling codes have better performance than the extended TDMA fixed assignment scheme in terms of code length, minimum guaranteed throughput, and so on.
