Abstract
The problem under study is the Minimum Broadcast Time (MBT). We are given a simple graph and a singleton that owns a message. The goal is to disseminate the message as soon as possible, where the communication takes place between neighboring-nodes in a selective fashion and each forwarding takes one time-slot. The MBT serves as an inspirational problem for the design of delay-sensitive forwarding schemes. Since the problem belongs to the -Hard class, the literature offers heuristics, approximation algorithms and exact exponential-time solutions.
The contributions of this paper are two-fold. First, an ILP formulation for the problem is provided. Second, a competitive heuristic is developed. A fair comparison between TreeBlock and previous heuristics highlights the effectiveness of our proposal.
期刊介绍:
Electronic Notes in Discrete Mathematics is a venue for the rapid electronic publication of the proceedings of conferences, of lecture notes, monographs and other similar material for which quick publication is appropriate. Organizers of conferences whose proceedings appear in Electronic Notes in Discrete Mathematics, and authors of other material appearing as a volume in the series are allowed to make hard copies of the relevant volume for limited distribution. For example, conference proceedings may be distributed to participants at the meeting, and lecture notes can be distributed to those taking a course based on the material in the volume.
