Smart Grid Communications: Overview of Research Challenges, Solutions, and Standardization Activities
Optimization of energy consumption in future intelligent energy networks (or
Smart Grids) will be based on grid-integrated near-real-time communications
between various grid elements in generation, transmission, distribution and
loads. This paper discusses some of the challenges and opportunities of
communications research in the areas of smart grid and smart metering. In
particular, we focus on some of the key communications challenges for realizing
interoperable and future-proof smart grid/metering networks, smart grid
security and privacy, and how some of the existing networking technologies can
be applied to energy management. Finally, we also discuss the coordinated
standardization efforts in Europe to harmonize communications standards and
protocols.Comment: To be published in IEEE Communications Surveys and Tutorial
FAIR: Forwarding Accountability for Internet Reputability
This paper presents FAIR, a forwarding accountability mechanism that
incentivizes ISPs to apply stricter security policies to their customers. The
Autonomous System (AS) of the receiver specifies a traffic profile that the
sender AS must adhere to. Transit ASes on the path mark packets. In case of
traffic profile violations, the marked packets are used as a proof of
misbehavior.
FAIR introduces low bandwidth overhead and requires no per-packet and no
per-flow state for forwarding. We describe integration with IP and demonstrate
a software switch running on commodity hardware that can switch packets at a
line rate of 120 Gbps, and can forward 140M minimum-sized packets per second,
limited by the hardware I/O subsystem.
Moreover, this paper proposes a "suspicious bit" for packet headers - an
application that builds on top of FAIR's proofs of misbehavior and flags
packets to warn other entities in the network.Comment: 16 pages, 12 figure

Trust in social machines: the challenges
The World Wide Web has ushered in a new generation of applications constructively linking people and computers to create what have been called ‘social machines.’ The ‘components’ of these machines are people and technologies. It has long been recognised that for people to participate in social machines, they have to trust the processes. However, the notions of trust often used tend to be imported from agent-based computing, and may be too formal, objective and selective to describe human trust accurately. This paper applies a theory of human trust to social machines research, and sets out some of the challenges to system designers
Questions related to Bitcoin and other Informational Money
A collection of questions about Bitcoin and its hypothetical relatives
Bitguilder and Bitpenny is formulated. These questions concern technical issues
about protocols, security issues, issues about the formalizations of
informational monies in various contexts, and issues about forms of use and
misuse. Some questions are formulated in the more general setting of
informational monies and near-monies.
We also formulate questions about legal, psychological, and ethical aspects
of informational money. Finally we formulate a number of questions concerning
the economical merits of and outlooks for Bitcoin.Comment: 31 pages. In v2 the section on patterns for use and misuse has been
improved and expanded with so-called contaminations. Other small improvements
were made and 13 additional references have been include
