In this paper, we propose IoTChain, a combination of the OSCAR architecture [1] and ACE authorization framework [2] to provide an E2E solution for secure authorized access IoT resources. IoTChain consists two components, blockchain based on object security model, extended with group key scheme. The provides flexible trustless way handle while uses public ledger set up multicast groups clients. To evaluate feasibility our architecture, have implemented top private Ethereum network. We report...
RPL, the routing protocol proposed by IETF for IPv6/6LoWPAN Low Power and Lossy Networks has significant complexity. Another called LOADng, a lightweight variant of AODV, emerges as an alternative solution. In this paper, we compare performance two protocols in Home Automation scenario with heterogenous traffic patterns including mix multipoint-to-point point-to-multipoint routes realistic dense non-uniform network topologies. We use Contiki OS Cooja simulator to evaluate behavior ContikiRPL...
Although LoRaWAN offers many advantages, one of its main limitation is the insufficient downlink capacity in large-scale scenarios. This makes reliable communication impractical as, LoRaWAN, reliability achieved through acknowledgement confirmed messages. The contribution this paper to provide a comprehensive description problems associated with presence traffic and propose solutions enable use acknowledgments for low medium load. proposed mechanisms build on more adequate flexible choice...
This paper investigates the sinks mobility in IPv6- based wireless sensors networks and specially new IETF proposed protocol RPL (Routing Protocol for Low power Lossy Networks). We also show that even of is not an explicit design criteria, use mobile improves network lifetime. In this work, we propose a distributed weighted moving strategy RPL. compared our approach with different others strategies. The results notably balances load which leads to significant lifetime gain large scale network.
This paper focuses on the performance of wireless sensor networks characterized by a hybrid topology composed mobile and static nodes. The Routing Protocol for Low power lossy (RPL), which is standardized as an IPv6 routing protocol low networks, uses trickle timer algorithm to handle changes in network topology. However, this not well adapted dynamic environments. enhances order fit with mobility requirements. Most previous works have improved without considering random movement In work,...
This paper focuses on wireless sensor networks (WSNs) for healthcare and medical applications which aim to look after patients by monitoring vital signs, diagnostics drug administrations. WSNs in such are usually composed of different types small-size battery powered sensors. In fact, wearable sensors used collect information about the signs a person that needs care. Static sensors, deployed inside hospital or home building, indoor environment. The collected data is then transmitted towards...
Billions of smart, but constrained objects wirelessly connected to the global network require novel paradigms in design. New protocol standards, tailored devices, have been designed taking into account requirements such as asynchronous application traffic, need for caching, and group communication. The existing connection-oriented security architecture is not able keep up-first, terms supported features, also scale resulting latency on small devices. In this paper, we propose an that...
In this paper, we present the results of extensive experiments on a testbed in The Things Network (TTN), public LoRa network. We evaluate transmission quality links by measuring Packet Reception Rate (PRR) as function payload length. show that there is only slight impact length PRR, which means bit error rate does not strongly influence probability packet reception. Our measurements channel behaves like slow fading Rayleigh channel, translates into Ps being (or not) favorable condition for...
In this paper, we propose a communication stack for powerline (PLC) based on open standards. Our aim is to provide interoperability features regarding others mediums with robust and reliable smart metering, home control or area networks applications. work the adaptation of IEEE 802.15.4 standard protocol. It constrained by low-power, lossy low data-rate context transceiver that uses pulse modulation. We first make quick survey justify use over PLC drawing parallel Low-Rate Wireless Personal...

Presents a scalable protocol for conducting periodic probes of network performance in way that minimizes collisions between separate probes. The goal the is to enable active monitoring large-scale distributed computational systems and networks. We use generate time series measurement data are then exposed numerical forecasting models when prediction required. present demonstrate its effectiveness using Network Weather Service -a tool dynamically predicting network, CPU, memory storage performance.
This paper introduces our work on the communication stack of wireless sensor networks. We present IPv6 approach for networks called 6LoWPAN in its IETF charter. then compare different implementations subsets several nodes platforms. implementation which aims to preserve advantages modularity while keeping a small memory footprint and good efficiency.
In this paper we propose a new authorization and authentication framework for the IoT that combines security model of OAuth 1.0a with lightweight building blocks ACE. By designing self-securing tokens no longer depends on network stack. We use basic PKI functionalities to bootstrap chain-of-trust between devices which simplifies future token exchanges. Finally, an alternate key establishment scheme cases where cannot directly communicate. test our proposal by implementing critical aspects...
Embedded devices of the Internet Things form so-called low-power and lossy networks. In these networks, nodes are constrained in terms energy, memory, processing. Links exhibit a transient behavior. From point view energy expenditure, governing control overhead emission is crucial role Trickle algorithm. We address Trickle's fairness problem to evenly distribute transmission load across network, while keeping total message count low. First, we analytically analyze two underlying causes...
A growing portion of scientists realises the need to not only alert about climate change, but also change their professional practices. range tools have emerged promote more sustainable activities, yet many struggle go beyond simple awareness-raising create concrete transition actions. Here we propose a game-based support system MaTerre180’ , which has been designed build scenarios greenhouse gas (GHG) emission reductions in academic community. After providing common scientific background...
