Abstract: 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-channel 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.
