The book aims to provide a broad overview of various topics of the Internet of Things (IoT) from the research and development priorities to enabling technologies, architecture, security, privacy, interoperability and industrial applications. It is intended to be a standalone book in a series that covers the Internet of Things activities of the IERC ? Internet of Things European Research Cluster from technology to international cooperation and the global "state of play". The book builds on the ideas put forward by the European research Cluster on the Internet of Things Strategic Research Agenda and presents global views and state of the art results on the challenges facing the research, development and deployment of IoT at the global level.

Internet of Things: Converging Technologies for Smart Environments and Integrated Ecosystems

Computer communications

Since a large scale Wireless Sensor Network (WSN) is to be completely
 integrated into Internet as a core part of Internet of Things (IoT) or Cyber
 Physical System (CPS), it is necessary to consider various security
 challenges that come with IoT/CPS, such as the detection of malicious
 attacks. Sensors or sensor embedded things may establish direct communication
 between each other using 6LoWPAN protocol. A trust and reputation model is
 recognized as an important approach to defend a large distributed sensor
 networks in IoT/CPS against malicious node attacks, since trust establishment
 mechanisms can stimulate collaboration among distributed computing and
 communication entities, facilitate the detection of untrustworthy entities,
 and assist decision-making process of various protocols. In this paper, based
 on in-depth understanding of trust establishment process and quantitative
 comparison among trust establishment methods, we present a trust and
 reputation model TRM-IoT to enforce the cooperation between things in a
 network of IoT/CPS based on their behaviors. The accuracy, robustness and
 lightness of the proposed model is validated through a wide set of
 simulations.

TRM-IoT: A trust management model based on fuzzy reputation for internet of things

Trust is an important aspect of mobile adhoc networks (MANETs). It enables entities to cope with uncertainty and uncontrollability caused by the free will of others. Trust computations and management are highly challenging issues in MANETs due to computational complexity constraints, and the independent movement of component nodes. This prevents the direct application of techniques suited for other networks. In MANETs, an untrustworthy node can wreak considerable damage and adversely affect the quality and reliability of data. Therefore, analyzing the trust level of a node has a positive influence on the confidence with which an entity conducts transactions with that node. In this work we present a detailed survey on various trust computing approaches that are geared towards MANETs. We highlight the summary and comparisons of these approaches. In addition, we analyze various works on trust dynamics including trust propagation, prediction and aggregation algorithms, the influence of network dynamics on trust dynamics and the impact of trust on security services.

Trust Computations and Trust Dynamics in Mobile Adhoc Networks: A Survey

Trust-based security for wireless ad hoc and sensor networks

Providing security and privacy in mobile ad hoc networks has been a major issue over the last few years. Most research work has so far focused on providing security for routing and data content, but nothing has been done in regard to providing privacy and anonymity over these networks. We propose a novel distributed routing protocol which guarantees security, anonymity and high reliability of the established route in a hostile environment, such as an ad hoc wireless network, by encrypting the routing packet header and abstaining from using unreliable intermediate nodes. The major objective of our protocol is to allow trustworthy intermediate nodes to participate in the path construction protocol without jeopardizing the anonymity of the communicating nodes. We describe our protocol, SDAR (secure distributed anonymous routing), and provide its proof of correctness.

An efficient secure distributed anonymous routing protocol for mobile and wireless ad hoc networks

A mobile ad hoc network consists of mobile nodes that can move freely in an open environment. Communicating nodes in a wireless and mobile ad hoc network usually seek the help of other intermediate nodes to establish communication channels. In such an open environment, malicious intermediate nodes can be a threat to the security and/or anonymity of the exchanged data between the mobile nodes. While data encryption can protect the content exchanged between nodes, routing information may reveal valuable information about end users and their relationships. The main purposes of this paper are to study the possibility of achieving anonymity in ad hoc networks, and propose an anonymous routing protocol, similar to onion routing concept used in wired networks. Our protocol includes a mechanism to establish a trust among mobile nodes while avoiding untrustworthy nodes during the route discovery process. The major objective of our protocol is to allow only trustworthy intermediate nodes to participate in the routing protocol without jeopardizing the anonymity of the communicating nodes. We present our scheme, and report on its performance using an extensive set of simulation set of experiments using ns-2 simulator. Our results indicate clearly that anonymity can be achieved in mobile ad hoc networks, and the additional overhead of our scheme to DSR is reasonably low when compared to a non-secure DSR ad hoc routing protocol.
