Current inventory-taking methods (counting stocks and checking correct placements) in large vertical warehouses are mostly manual, resulting (i) personnel costs, (ii) human errors (iii) incidents due to working at heights. To remedy this, the use of autonomous indoor drones has been proposed. However, these require accurate localization solutions that easy (temporarily) install low costs warehouses. this end, we designed a Ultra-Wideband (UWB) solution uses infrastructure anchor nodes do not...
Mesh networks enable a many-to-many relation between nodes, which means that each node in the network can communicate with every other using multi-hop communication and path diversity. As it enables fast roll-out of sensor actuator networks, is an important aspect within Internet Things (IoT). Utilizing Bluetooth Low Energy (BLE) as underlying technology to implement such mesh has gained lot interest recent years. The result was variety BLE meshing solutions were not interoperable because...
Ultra-wideband (UWB) localization is one of the most promising approaches for indoor due to its accurate positioning capabilities, immunity against multipath fading, and excellent resilience narrowband interference. However, UWB researchers are currently limited by small amount feasible open source hardware that publicly available. We developed a new platform, Wi-PoS, precise based on Decawave’s DW1000 transceiver with several unique features: support both long-range sub-GHz 2.4 GHz back-end...
Accurate radio frequency (RF)-based indoor localization systems are more and applied during sports. The most accurate RF-based use ultra-wideband (UWB) technology; this is why technology the prevalent. UWB positioning allow for an in-depth analysis of performance athletes training competition. There no research available that investigates feasibility track cycling. In paper, we investigate optimal position to mount hardware specific case. Different positions on bicycle cyclist were evaluated...
Smart embedded objects such as sensors and actuators will become an important part of the Internet Things. With recent technologies, it has now possible to deploy a sensor network interconnect with IPv6 Internet. However, several manual configuration steps are still needed integrate within existing networking environment. In this paper we describe novel self-organization solution facilitate deployment networks enable discovery, end-to-end connectivity service usage these newly deployed...
Smart embedded objects will become an important part of what is called the Internet Things. Applications often require concurrent interactions with several these and their resources. Existing solutions have limitations in terms reliability, flexibility manageability such groups objects. To overcome we propose intermediately level intelligence to easily manipulate a group resources across multiple smart objects, building upon Constrained Application Protocol (CoAP). We describe design our...
The Internet of Things (IoT) domain is characterized by many applications that require low bandwidth communication over a long range at cost and power, which has given rise to novel Low Power Wide Area Network (LPWAN) technologies operate in the sub-GHz domain. Today, these are being adopted more complex settings configurations than originally intended. Devices equipped with multiple LPWAN radio satisfy diverse requirements, connecting different networks times locations. Further,...
In many industrial application domains, such as industry 4.0, logistics, process automation and personalized services, there is a need to operate in more efficient less time consuming way. Efficiency studies often involve simulations fundamental step verify analyze the performance of novel solutions.

To remedy this, paper proposes a TDMA protocol for large scale localization network numerous simultaneously active users. end, full system was designed handles...
The increasing elderly population and the shift from acute to chronic illness makes it difficult care for people in hospitals rest homes. Moreover, people, if given a choice, want stay at home as long possible. In this article, methodologies develop cloud-based semantic system, offering valuable information knowledge-based services, are presented. services related different personal living hemispheres of patient, namely daily care-related needs, social needs life assistance. Ontologies used...
Today, the IETF Constrained Application Protocol (CoAP) is being standardised. CoAP takes internet of things to next level: it enables implementation RESTful web services on embedded devices, thus enabling construction an easily accessible things. However, before tiny objects can make themselves available through services, several manual configuration steps are still needed integrate a sensor network within existing networking environment. In this paper, we describe novel selforganisation...
