我们建立了一个集中控制下的单跳移动的网络模型,该网络具有N个服务类别,可以看作是一个N个加权代价并行队列的系统,每个队列具有M(1 ≤ M < N)个服务器、到达者、不同的二进制连通性和伯努利服务成功率。我们认为在这个系统中的调度问题,并在各种假设下到达和连接,推导出充分的条件,但不是必要的,以保证最优的索引政策。
We model a single-hop mobile network under centralized control with N service classes as a system of N weighted cost parallel queues with M (1 ≤ M < N) servers, arrivals, varying binary connectivity, and Bernoulli service success at each queue. We consider scheduling problems in this system and, under various assumptions on arrivals and connectivity, derive conditions sufficient, but not necessary, to guarantee the optimality of an index policy.
