一种高效存储的自稳定BFS生成树的分析

Analysis of a Memory-Efficient Self-Stabilizing BFS Spanning Tree

Ajoy K. Datta, Stéphane Devismes, Colette Johnen, Lawrence L. Larmore

摘要:

我们目前的结果上的最后一个主题,我们与我们已故的朋友,教授阿霍伊库马尔达塔(1958-2019)合作。在这项工作中,我们揭示了新的光在1997年由Colette Johnen提出的自稳定波算法。该算法在任意连通的有根网络中构造BFS生成树。目前,它仍然是现有的最好的自稳定BFS生成树结构,在内存需求方面,{ \em即},它只需要每个边缘的$Θ(1)$比特。然而,它已经被证明假设一个弱公平的守护进程。此外,它的稳定时间也是未知的。在这里,我们研究这个算法的稍微修改的版本,仍然保持相同的内存需求。我们证明了这个变种下的分布式不公平守护进程的自稳定性,并显示稳定时间在$O(D.n^2)$轮,其中$D$是网络直径和$n$进程的数量。

英文摘要:

We present results on the last topic we collaborate with our late friend, Professor Ajoy Kumar Datta (1958-2019). In this work, we shed new light on a self-stabilizing wave algorithm proposed by Colette Johnen in 1997. This algorithm constructs a BFS spanning tree in any connected rooted network. Nowadays, it is still the best existing self-stabilizing BFS spanning tree construction in terms of memory requirement, {\em i.e.}, it only requires $Θ(1)$ bits per edge. However, it has been proven assuming a weakly fair daemon. Moreover, its stabilization time was unknown. Here, we study the slightly modified version of this algorithm, still keeping the same memory requirement. We prove the self-stabilization of this variant under the distributed unfair daemon and show a stabilization time in $O(D.n^2)$ rounds, where $D$ is the network diameter and $n$ the number of processes.
