With the continuous progress of rural construction, the problem of rural drinking water pollution is increasingly prominent. In view of water pollution, a design of rural drinking water monitoring system based on wireless sensor networks is proposed that nodes take STM32 as the core chip and WLK01L39 as well as its peripheral circuits are used as wireless communication modules and Beidou S1216 is...
In order to solve the existing traditional rural drinking water monitoring in a lot of manpower, material resources, real-time, this paper introduces a WSN based on the rural drinking water source monitoring system design, the system consists of five parts: water quality monitoring, soil monitoring node node, node, routing node and gateway server. Water quality monitoring node, soil monitoring nodes...
Wireless sensor network is one of the effective tools for data gathering in a variety of environments which has a lot of challenges. Controlling the congestion is one of the challenges that primarily depends on the way the large number of sensors in a network are organized and controlled. A group of nodes is called a cluster which sends information to the gateway through the cluster head. This structure...
Anonymous communications are growing extremely fast because more and more Internet users employ anony mous systems, such as the I2P or Tor networks, as a way to hide their online activity. Therefore, these networks have been more and more studied, mainly from a security point of view. Different studies have shown important design flaws in these systems that could break users' anonymity and how these...
Event detection is an important part in many Wireless Sensor Network (WSN) applications such as forest fire, environmental pollution. In this kind of applications, the event must be detected early in order to reduce the threats, damages. In this paper, we propose a new approach for early forest fire detection, which is based on the integration of Data Mining techniques into sensor nodes. The idea...
In this paper, we propose an autonomic network management system that analyzes, evaluates, and optimizes the redundancy of routes providing access to remote sites from a local area network. The proposed solution ARRC is based on SNMP as simple network management protocol to monitor the gateways, analyze their layer 3 operations and perform an extra configuration that enhances the availability of network...
In most monitoring applications, Wireless Sensor Networks (WSNs) are configured to monitor and transmit the sensing data periodically. In case of normal conditions, when the environment does not change frequently, the collected values are usually the same. Hence, the received data do not provide enough meaningful information for making decisions. In this paper, we propose a flexible context-aware...
Extensive use of wireless sensor networks for various applications like surveillance, habitat monitoring, battlefield etc., demand high probability of coverage and connectivity. The first issue deals with how well the sensor network will be able to detect the event by the sensor nodes and secondly, how efficiently the information will be communicated to the gateway node. In many applications, sensors...
In recent years wireless sensor networks are widely used in many automated system like vehicle monitoring, heavy duty plants, robotic control etc. one of the best automated systems is the smart irrigation system. In this paper we have proposed a simple and cost effective smart irrigation system. Our system deploys wireless sensor motes from a wireless sensor network. The system is modelled in outdoor...
The widespread deployment of Automatic Metering Infrastructures in Smart Grid scenarios rises great concerns about privacy preservation of user-related data, from which detailed information about customer's habits and behaviours can be deduced. Therefore, the users' individual measurements should be aggregated before being provided to External Entities such as utilities, grid managers and third parties...
In this paper we consider a remote monitoring scenario where the monitoring center is geographically located far away from the region of the deployed sensor network, and the sensing data by the sensors is transmitted to the monitoring center through a third party telecommunication service, thus a cost associated with this service will be incurred, which is related to the amount of data successfully...
ZigBee wireless technology is a global standard of short-range and low-data-rate for wireless sensor networks. To reduce the redundant overhead and to conserve nodes' energy in energy-constrained and multi-PAN ZigBee networks, we propose in this paper a cross-layer energy-balanced inter-PAN routing algorithm (CEIPR). The proposed algorithm has three key functionalities: (1) establishes the multipath...
We propose m-courses (Monitoring Courses), a novel solution to localize events in an underwater wireless sensor network. These networks consists of surface gateways and relay nodes. GPS can localize the position of surface gateways which can then distribute their locations through the network using acoustic modems. Relay nodes are deployed to remain static, but these untethered nodes may drift due...
Aiming at the current situation of hydrological monitoring, integrating with the application of internet of things in hydrological monitoring area, to realize automation of hydrological monitoring, the system for hydrologie monitoring based on internet of things is designed. This system is constructed with internet of things technology, software technology, evaluated network technology, etc. The system...
Internet and web services contribute to the future of healthcare delivery due to the wide deployment of IP networks around the world. Meanwhile, sensor network as an emerging technology for delivering health information has been attracting more and more attentions recently. As most of existing sensor networks have not been deployed with IP protocol, complex multi-protocol gateways are needed to connect...
Today, design automation approaches for automotive E/E-architectures focus solely on application functionality, neglecting firmware-related functionalities like diagnostic tests that are of utmost importance for quality features such as dependability or maintenance. However, the latter are typically considered dispensable since they do not provide direct service to the user. This paper proposes a...
Future network should focus more on what users want to get from the network rather than where users want to get through the network. Distributed content network equipped with storage and streaming server could provide effective and efficient content service to the users. We propose the hierarchical content management method to find the optimal content server in consideration of load balancing over...
A human vital monitoring system using Ad Hoc wireless network is implemented to enhance the healthcare service. Issues related to hardware and software implementation including the data packet format are addressed. The system uses a low cost electrocardiogram (ECG) sensor to monitor patient's vital sign. A sensor node, which is held by the patient, transmits the sensor data via an Ad Hoc wireless...
everal protocols for routing and forwarding in Wireless Mesh Networks (WMN) have been proposed, such as AODV, OLSR or B.A.T.M.A.N. However, providing support for e.g. flow-based routing where flows of one source take different paths through the network is hard to implement in a unified way using traditional routing protocols. OpenFlow is an emerging technology which makes network elements such as...
Multi-hop wireless networks are emerging as a viable alternative for building access networks in areas where conventional solutions (cellular, fiber) are neither feasible nor attractive from an economical standpoint. The management of such networks represents an overly complex task because of the time-varying nature of the radio channel, the mobility of users and the presence of adaptive, self-configuration...
