Distributed H∞ filtering over multiple-channel sensor networks with Markovian channel switching and time-varying delays

چکیده
This paper is concerned with distributed H∞ filtering for a class of continuous-time linear plants over sensor networks with multiple communication channels (MCCs). A practical framework is presented to optimize communication over MCCs with uncertain delays and switching characteristics. The channel switching is assumed to follow a continuous-time Markov chain and a Markov jump linear system (MJLS) is exploited to model the overall networked system. A class of Lyapunov-Krasovskii functionals are constructed to derive sufficient conditions on stochastic stability and H∞ performance of the MJLS in terms of linear matrix inequalities. Furthermore, the filtering parameter design is presented by employing Projection Lemma and LMI techniques.

Tracking performance of incremental LMS algorithm over adaptive distributed sensor networks
in this paper we focus on the tracking performance of incremental adaptive LMS algorithm in an adaptive network. For this reason we consider the unknown weight vector to be a time varying sequence. First we analyze the performance of network in tracking a time varying weight vector and then we explain the estimation of Rayleigh fading channel through a random walk model. Closed form relations a...

This paper is concerned with distributed sampled-data asynchronous H1 filtering for a continuous-time Markovian jump linear system over a sensor network, where jumping instants of system modes and filter modes are asynchronous. A group of sensor nodes are deployed to measure the system's output and to collaboratively share the measurement with neighboring nodes in accordance with Markovian swit...

متن کاملMulti-channel Medium Access Control Protocols for Wireless Sensor Networks: A Survey
Extensive researches on Wireless Sensor Networks (WSNs) have been performed and many techniques have been developed for the data link (MAC) layer. Most of them assume single-channel MAC protocols. In the usual dense deployment of the sensor networks, single-channel MAC protocols may be deficient because of radio collisions and limited bandwidth. Hence, using multiple channels can significantly ...
