Abstract

Objectives: This study is centered on four issues related to the reliability evaluation in multi-source multi-sink networks. Each issue discusses the reliability evaluation under different condition. These conditions play an important role in determining the quickest paths used in transmitting data between source and sink nodes, with the condition that the transmission time of the quickest path does not surpass a predetermined upper bound T. Methods/Statistical Analysis: Proposed algorithms used in each issue designed based on approaches taken from previous literatures to evaluate the reliability. Findings: The reliability ( R_dwjT ) evaluated when each source transmits the demand d_wj (the demand for resource w at sink node t_j ) separately to the distinct sink, this is the first issue. The second issue deals with transmitting demands request by sink nodes from one source via a group of disjoint paths. In the case of transmitting demands through a gathering of joint paths, share one or more common arc, this is the third one. The last issue investigates the problem of sending demands requested by all sinks from all sources via joint paths. Application/Improvements: Examples are presented to illustrate how to evaluate the reliability of a multi-source multi-sink networking each case under time constraint.
