This paper presents an interleaved boost converter (IBC) with ripple cancellation network (RCN). Based on the conventional IBC, two capacitors, two coupled inductors, and two inductors are added as RCN in the proposed converter. Therefore, the proposed converter shares the same advantages of the conventional IBC and achieves input current ripple cancellation without significantly increasing the current...
Sink Scheduling, in the form of scheduling multiple sinks among sink sites to leverage traffic burden, is an effective mechanism for the energy-efficiency of wireless sensor networks (WSNs). Due to the inherent difficulty (NP-hard in general), existing works on this topic mainly focus on heuristic/greedy algorithms and theoretic results remain unknown. In this paper, we fill in the research blank...
Network tomography has been proposed to ascertain internal network performances from end-to-end measurements. In this work, we present priority probing, an optimal probing scheme for unicast network delay tomography that is proven to provide the most accurate estimation. We first demonstrate that the Fisher information matrix in unicast network delay tomography can be decomposed into an additive form...
In the recent years, a progressively growing number of computing and communication services have undertaken the migration from their conventional media to the new unified platform, IP networks. As a consequence, business success of service providers becomes largely determined by the effectiveness of their service management schemes, which require rapid identification of problems and resolution of...
