To widen the control over a factory from purely wire based to the wireless domain, both secure and reliable communication infrastructure with real-time capabilities is needed. Based on wireless communication technologies , such infrastructures may be used to gain new flexibility within any step of a manufacturing process hence enabling the development of(More)
—Clock synchronization is one of the enabling technologies for real-time networking. This paper is motivated by the need for WLAN support of real-time factory automation networks. These networks need synchronized clocks for the typical time-slotted arbitration schemes. As this type of service is not yet available wireless LANs, this work investigates(More)
—Between the wired and the wireless world a synchronization gap in terms of accuracy obviously exists due to the different possibilities of the technologies. This paper investigates means to access WLAN functionality in order to gain system-wide synchronization between access points and clients in order to establish a common notion of time in IEEE 802.11(More)
The usage of WLANs (Wireless Local Area Networks) for both office and non office (e.g. factory automation) applications is one of today's upcoming trends. However the usage of WLAN suffers from the problem that nowadays one cannot determine the exact position of standard compliant wireless nodes. This paper presents an approach for location based services(More)
Sparse-matrix solution is a dominant part of execution time in simulating VLSI circuits by a detailed simulation program such as SPICE. The paper develops a parallel-block partitionable sparse-matrix-solution algorithm which exploits sparsity at the matrix block level as well as within a nonzero block. An efficient mapping scheme to assign different matrix(More)
