Abstract
AbstractThe quickest path problem deals with the transmission of a message of size σ from a source to a destination with the minimum end-to-end delay over a network with bandwidth and delay constraints on the links. We adapt properties of the quickest path to solve the delay-bounded minimum-cost (DBMC) path problem that is known to be the NP-hard. In this paper, we propose two efficient and simple algorithms, DBMCQP and DBMCQRT. DBMCQP computes a DBMC quickest path for a given message size σ with O(rm + rnlogn), and DBMCQRT construct DBMC routing tables taking into account multiple delay-bounds for any size of message with O(kr 2), where r, n, m, and k are the number of distinct link-bandwidths, nodes, links of the network, and the number of delay-bounds, respectively.KeywordsShort PathMessage SizeDelay ConstraintIEEE INFOCOMDelay BoundThese keywords were added by machine and not by the authors. This process is experimental and the keywords may be updated as the learning algorithm improves.
