[chapter]
2014
Lecture Notes in Computer Science
Preserved Fulltext
On the positive side, we propose an optimal protocol for Periodic Data Retrieval in asynchronous rings with a gray hole, which solves the problem with only 4 agents. ...
In a recent work, Královič and Miklík [SIROCCO 2010, LNCS 6058, pp. 157-167] considered various types of malicious host behavior in the context of the Periodic Data Retrieval problem in asynchronous ring ...
Moreover, we proposed an optimal, with respect to the number of agents, protocol for Periodic Data Retrieval in asynchronous rings with a gray hole, improving the previous upper bound of 9 agents and settling ...
