This paper describes the adaptation of a computational technique utilizing Extended Kohonen Maps (EKMs) and Rao-Blackwell-Kolmogorov (R-B) Filtering mechanisms for the administration of Sensor-Actuator networks (SANETs). Inspired by the BDI (Belief-Desire-Intention) Agent model from Rao and Georgeff, EKMs perform the quantitative analysis of an algorithmic artificial neural network process by using an indirect-mapping EKM to self-organize, while the Rao-Blackwell filtering mechanism reduces the external noise and interference in the problem set introduced through the self-organization process. Initial results demonstrate that a combinatorial approach to optimization with EKMs and Rao-Blackwell filtering provides an improvement in event trajectory approximation in comparison to standalone cooperative EKM processes to allow responsive event detection and optimization in patient healthcare.

Obliczenie niezawodności sieci sensorowej i akcyjnej jest złożonym zagadnieniem. Skomplikowana struktura sieci powoduję, że jest niemożliwe opracowanie bezpośredniej metody obliczeń. Zaproponowano zastosowanie metody, polegającej na skonstruowaniu równoważnej pod względem niezawodności struktury równoległo-szeregowej na podstawie zbioru przekrojów grafu sieci sensorowej i akcyjnej. W pracy pokazano, jak liczba i rząd uwzględnionych przekrojów wpływają na dokładność obliczeń niezawodności sieci.

Computing the reliability of a sensor and actor network is a complex task. The complicated network structure causes that it is impossible to work out a direct computation method. To compute the network reliability, there is proposed a method consisting in construction of a parallel-series structure of equivalent reliability with use of graph cuts of the sensor and actor network. In the paper it is shown how the number and order of elements in the considered cuts used for computations influence the accuracy of reliability calculations.

This paper discusses the results of utilizing advanced EKM modeling techniques to manage Sensor-Actor networks (SANETs) based upon the Holonic Architectural Framework. EKMs allow a quantitative analysis of an algorithmic artificial neural network process by using an indirect-mapping EKM to self-organize from a given input space to administer SANET routing and clustering functions with a control parameter space. Results demonstrate that in comparison to linear approximation techniques, indirect mapping with EKMs provide fluid control and feedback mechanisms by operating in a continuous sensory control space – thus enabling interactive detection and optimization of events in real-time environments.
