520 | a Data networks are an important part in an increasing number of applications with real-time and reliability requirements. To meet these demands a variety of approaches have been proposed. Forward error correction, which adds redundancy to the communicated data, is one of them. However, the redundancy occupies communication bandwidth, so it is desirable to control the amount of redundancy in order to achieve high reliability without adding excessive communication delay. The main contribution of the thesis is to formulate the problem of adjusting the redundancy in a control framework, which enables the dynamic properties of error correction control to be analyzed using control theory. The trade-off between application quality and resource usage is captured by introducing an optimal control problem. Its dependence on the knowledge of the network state at the transmission side is discussed. An error correction controller that optimizes the amount of redundancy without relying on network state information is presented. This is achieved by utilizing an extremum seeking control algorithm to optimize the cost function. Models with varying complexity of the resulting feedback system are presented and analyzed. Conditions for convergence are given. Multiple-input describing function analysis is used to examine periodic solutions. The results are illustrated through computer simulations and experiments on a wireless sensor network. | |

Finns inte boken du söker på ditt bibliotek? Då kan biblioteket i många fall låna in den från ett annat bibliotek genom ett så kallat fjärrlån.
För ett trettiotal bibliotek kan man själv som låntagare göra beställningar direkt via ett formulär i LIBRIS (LIBRIS låntagarbeställningar), dessa bibliotek är listade nedan. Mer om fjärrlån
Många bibliotek erbjuder beställningsformulär för fjärrlån på sina webbplatser. Kontakta ditt bibliotek för mer information.
