Title: An Approach to Modular Design for Security Protocols Based on the Fail-Stop Property

Authors: FEI Xiangdong, PAN Yu
PP: 848～855
Abstract: An approach to designing Fail-Stop protocols is put forward, i.e., minimum Fail-Stop protocols as compositional modules are first designed, more complicated protocols are composed of these modules， the clarity and readability of protocol structure are regarded as the standard of estimating protocol quality. NSPK and Otway-Rees authentication protocols are designed with this approach. On the basis of an improved Woo-Lam authentication protocol and a non-repudiation protocol being pointed out to consist of flaws, they are revised and turned into Fail-Stop protocols.

Abstract: Approximate point-in-triangulation test (APIT)， which is one of the localization algorithms for wireless sensor networks, is improved in this paper. The purpose is to improve the original algorithm in positioning accuracy and implement efficiency.

Simulation results show that the improved APIT algorithm can improve the positioning accuracy effectively without increasing hardware consumption comparing with conventional APIT algorithm. Furthermore, the algorithm is simple and needs small amount of calculation, so it has general engineering significance.

Title: Robust predictive control for networked control systems with long time delays

Authors: LIU Andong, YU Li, ZHANG Wenan
PP: 762～768
Abstract: The robust predictive state feedback controllers design problem is investigated in this paper for a class of networked control systems (NCSs) with uncertain long delays and input constraints. The designed controllers guarantee that the closed-loop NCS is asymptotically stable and that the on-line receding horizon performance index is minimized. Sufficient conditions for the closed-loop NCS to be asymptotically stable and the robust performance index to be upper bounded is derived by using the receding optimization principle. Furthermore, the state feedback control law is obtained by solving a convex optimization problem with linear matrix inequalities (LMIs) constraints. Finally, an example is given to demonstrate the effectiveness of the proposed method.
