    There has been remarkable progress in sampled-data control theory in the last decade. The main accomplishment here is that there exists a digital (discrete-time) control law that takes the intersample behavior into account and makes the overall analog (continuous-time) performance optimal, in the sense of H-infinity norm. The same hybrid nature of designing a digital filter for analog signals is a... View full abstract»

    A mobile ad hoc network (MANET) is a collection of mobile nodes interconnected by wireless media. Several protocols have been proposed to manage multiple access to the shared wireless medium in MANETs, with the IEEE 802.11 being the most implemented protocol. Several approaches have been suggested to improve QoS in the famous IEEE 802.11 MANETs through modifying some of the IEEE 802.11 medium acce... View full abstract»

    This paper investigates the problem of model predictive control for networked multirate control systems (NMCSs) with the output sampling period several times larger than the input updating period. Both sensor-to-controller and controller-to-actuator network-induced delays are considered and are assumed to be upperbounded by one output sampling period. Firstly, using a modified multirate model pred... View full abstract»

  • Robust state estimation for systems with irregular sensing failure

    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (4081 KB) | HTML iconHTML

    This paper proposes a method for robust state estimation for systems with irregular sensing failure. It is natural that non-contact sensors sometimes give abnormal signals (outliers) due to sensing failure. The proposed estimator switches observer gains to select normal signals based on residual values between estimation and observation. A common Lyapunov function ensures stability of the switchin...

    In this paper, we propose a new routing protocol named micro sensor routing protocol (MSRP) in IPv6 wireless sensor network. MSRP is implemented in network layer and can simplify significantly routing mechanism. Also, we simplify the routing message and remove source and destination nodes' sequence numbers and reduce route request (RREQ) ID length. Route reply (RREP) is created only by the destina...

    The transmission power and the reception power are the main source of energy consumption in wireless sensor nodes. Therefore, reducing the amount of consumed power through the transmission and reception processes in the routing protocol will lead to an increase in the lifetime of the wireless sensor network and distribute the consumed power among the wireless sensor nodes.
