The IPv6 protocol adaptation for the Wireless Sensor Network (6LoWPAN) enables the reuse of the TCP/IP application layer in WSN environment. It has been shown that the Simple Network Management Protocol (SNMP) originally envisioned for monitoring & managing hosts on the internet can be adapted for the 6LoWPAN networks. Also, IETF Constrained Application Protocol (CoAP), designed specifically for...
According to aging trends and strategic orientation for providing higher healthcare standards, assisted living is one of the key research areas in the western world. Fall is the most common cause of injury of an elderly person. Therefore, with its timely detection we can ease its consequences or even avoid death. In this paper, we present architecture developed in Hrvatski Telekom that provides functionalities...
Machine-to-machine (M2M) communication with an M2M gateway is expected to spread rapidly with the penetration of smart devices and sensors. As increasing the number of connected devices leads to repetitive manual configuration on an M2M gateway, one of the key factors in M2M communication is ease in configuration for end-users. In this paper, a new server-assisted provisioning method for an M2M gateway...
This paper presents a prototype machine-to-machine (M2M) healthcare solution that combines mobile and IPv6 techniques in a wireless sensor network to monitor the health condition of patients and provide a wide range of effective, comprehensive, and convenient healthcare services. A low-power embedded wearable sensor measures the health parameters dynamically, and is connected, according to the concept...
Number of connected devices in Machine-to-Machine (M2M) systems is rapidly growing: according to famous predictions made by Ericsson, by the end of 2020 there will be 50 billion devices in M2M systems around the world. The idea to connect a plethora of devices, whether they are fixed, movable or fully mobile, that communicate through different technologies (e.g. wireline, 2G/3G/4G, WiFi, ZigBee, Bluetooth)...
In this paper, we implements intrusion detection system for video surveillance which works well in wireless sensor networks (WSN) environment. Our system has been implemented using open geospatial consortium standard, and operated in the android platform of mobile environment. We also have been implemented intruder detection by machine learning technique. As a result, our system can achieve real-time...
In this paper, based on the DDNS(Dynamic Domain Name Service) and port mapping technology, a method about server port mapping and server-side gateway dynamic DNS is introduced, which can be applied in Data Collecting System based on the Internet of Things. In this way, the external sensor-side gateway can access the intranet server which has a dynamic IP address.
Multi-Owner Wireless Sensor Networks consist of devices owned by different entities. They have the purpose of covering large areas and reducing energy consumption associated with transmission over long distances. We propose the use of Virtual Networks with the purpose of grouping resources in a Multi-Owner Wireless Sensor Network and delivering a service to the associated owner. We designed a scheme...
The IP Multimedia Subsystem (IMS) is one of the key components of third generation (3G) networks, while Wireless Sensor Networks (WSNs) are an emerging type of networks formed by a set of distributed sensor nodes that collaborate to monitor physical and environmental conditions. By integrating the sensing capabilities of WSNs in the IMS, a rich set of contextual information can be exploited to provide...
Wireless sensor networks (WSNs) are expected to be deployed in various areas in the future for monitoring and interacting with the physical environment. The sensors are constraint devices, so 6LoWPAN is proposed by IETF to adapt IPv6 into the WSNs environment. However, due to the use of short address and compression, IPv6/IPv4 enabled devices cannot support the 6LoWPAN adaptation layer as well as...
Unlike traditional networked embedded systems, the Internet of Things interconnects heterogeneous devices from various manufacturers with diverse functionalities. To foster the emergence of novel applications, this vast infrastructure requires a common application layer. As a single global standard for all device types and application domains is impracticable, we propose an architecture where the...
This paper studies the design of a wireless data acquisition system applied in greenhouse by building a wireless sensor network based on ZigBee. The system includes acquisiton terminals, routing nodes, an ethernet gateway and a server. The terminals are solar powered with no external power supply, which can be flexibly deployed. Through multiple sensors connected to it, the system can collect the...
This paper presents design and implementation of a homecare system that provides home control assistance and fall detection services using a wrist-watch type wireless motion and location sensing device. This user interface device is equipped with a Zigbee radio transceiver to communicate with a home gateway and track location of the user. The user interface device is also equipped with a 3-axis accelerometer...
The Internet of Things vision states that sensors and actuators shall be integrated into the global Internet to facilitate an interaction with and integration of the physical environment. The development of enabling technologies like uIPv6 and 6LoWPAN provide the basic requirements for this interconnection. However, a seamless Internet-connection and interconnection between sensors and actuators can...
The two most important objectives of the data center operators are to reduce operating cost and minimize carbon emission. Consolidation of data centers is not always possible and big enterprise end up having data centers in multiple locations across different cities and countries. In such a diverse deployment manual monitoring is not a cost effective solution. ASHRAE [1] suggested considering the...
A wireless sensor network collected real-time water-quality measurements to investigate how current irrigation practices—in particular, underground water salination—affect the environment. New protocols provided high end-to-end packet delivery rates in the hostile deployment environment.
Despite of the development of wireless sensor networks in recent years, there lacks a general mechanism to manage these network devices. Because most managing mechanisms for wireless sensor networks are proprietary, when multiple platforms of wireless sensors networks are deployed together, interoperability and scalability would become a big issue. In this paper, we propose to utilize Session Initiation...
Wireless sensor networks are used for monitoring phenomena using spatially distributed sensor nodes. A wireless sensor network may be far away from a server which collects and processes data from the network. In that case, one or more gateways are used to connect the network to the remote server via TCP/IP or UDP/IP. To speed up testing and deployment of a network, we have developed a simulator which...
