With the current increase in ad-hoc mobile networks in public domains (e.g. airports, cities, etc.), and the widespread use of IEEE802.11 wireless LAN, there is a growing need to handle and manage fast mobility. Extending the coverage area of ad-hoc networks and taking into account fast mobility in routing protocols could offer a complementary solution to the UMTS for fourth generation (4G) mob...

Ad hoc network infrastructure is dynamically changing, and the links are wireless with less capacity and more prone to errors. Adding trust to the existing security infrastructures would enhance the security of these environments. Describing components and their sub-components using ontologies, creates a methodology and mechanism in order to efficiently design. With a viewpoint to add trust as ...

New production environments will demand extensive exchange of communication information. Wireless communications will provide effective means to meet these demands. However, it is important that effective protocols are available to deliver the required QoS. Cross-layer algorithms are potential candidates that exhibit interesting features compared to monolithic traditional protocols. This paper ...

Java is still not a common language for embedded systems. It posses language features, like thread support, that can improve embedded system development, but common implementations as interpreter or just-in-time compiler are not practical. JOP is a hardware implementation of the Java Virtual Machine with focus on real-time applications. This paper describes the architecture of JOP and proposes ...

Systems engineering frequently includes efforts to reduce part count with the goal of cutting costs, enhancing performance, or improving reliability. This paper examines the engineering practices related to part count, applying three different theories -the Theory of Inventive Problem Solving, Axiomatic Design, and Highly Optimized Tolerance. Case studies from the jet engine industry are used t...
