—Whilst security is generally perceived as an important constituent of communication systems, this paper offers a viable security-communication-tradeoff particularly tailored to Advanced Metering Infrastructures (AMIs) in Smart Grid systems. These systems, often composed of embedded nodes with highly constrained resources, require e.g. metering data to be(More)
—With the majority of the population living in urban environments today, the concept of Smart Cities has become an urgent necessity. It refers to an urban transformation which, using latest ICT technologies, makes cities more efficient. Composed of a growing Internet of networks, such as the one connecting humans via cellular systems, computers via(More)
In this paper, we deal with the analytical performance study of spatial multiplexing (SM) multiple-input multiple-output (MIMO) systems experiencing flat Rayleigh fading and log-normal shadowing. We address the problem of finding a tractable expression for the symbol error outage (SEO) in this environment. In order to obtain the SEO, a symbol error(More)
Thus paper discusses an englneerlng design management system that Integrates prrnted clrcult board design data Into a database supported by a relattonal database management system In contrast to other reported systems that manage design data only, the system described facilitates design process management by enforcing procedural constraints Inherent In the(More)
This document presents a security threat analysis for the Routing Protocol for Low-Power and Lossy Networks (RPLs). The development builds upon previous work on routing security and adapts the assessments to the issues and constraints specific to low-power and lossy networks. A systematic approach is used in defining and evaluating the security threats.(More)
Status of This Memo This memo provides information for the Internet community. It does not specify an Internet standard of any kind. Distribution of this memo is unlimited. Abstract The application-specific routing requirements for Urban Low-Power and Lossy Networks (U-LLNs) are presented in this document. In the near future, sensing and actuating nodes(More)
