Abstract

We study the problem of online packet routing in dynamic store-and-forward directed line networks. We present a centralized randomized online algorithm that achieves a throughput that is O(logn)-competitive, where n denotes the number of nodes. Our algorithm is applicable to all values of buffer sizes and communication link capacities. In particular, it holds also for unit buffers.

This algorithm improves the best previous O(log2 n)-competitive ratio of [6] and considers links with unit capacities.
