  Abstract

Since the introduction of the back-pressure scheduling policy, tremendous efforts have been devoted to the packet schedulers achieving the optimal throughput in multi-hop wireless networks. Our understanding for the throughput performance has been matured now and the focus is migrating to the delay. Unfortunately, we have witnessed very limited success on the delay analysis of multi-hop networks even in the wireline domain. Noting that the previous literatures on schedulers commonly assume the separate session queues at each link, we are interested in the effect of queue aggregation on the delay performance of networks. For this purpose, we first analyze the stationary randomized scheduling policy with session queues (SRS-S). Then, the scheduler is modified to manage only a single queue at links, which is called the stationary randomized scheduling with link queues (SRS-L). By comparing the delay performances of SRS-S and SRS-L, we show that the queue aggregation reduces the average delay of packets significantly.
