With the development of Internet of Things and embedded computing technology, the smart home system has become a hot research spot of embedded systems. In this paper, through combining the Internet of Things, a smart home system based on zigbee and power line carrier communication technology is designed. In addition, the gateway is an important part of the smart home system, and its communication...
Understanding per-packet routing dynamics in deployed and complex wireless sensor networks (WSNs) has become increasingly important for many essential tasks such as network performance analysis, operation optimization, system maintenance, and network diagnosis. In this paper, we study routing path recovery for data collection in multi-hop WSNs at the sink using a very small and fixed path measurement...
In large-scale multi-hop wireless sensor networks (WSNs) for data collection, the ability of monitoring per-packet routing paths at the sink is essential in better understanding network dynamics, and improving routing protocols, topology control, energy conservation, anomaly detection, and load balance in WSN deployments. In this study, we consider this important problem under tremendous WSN routing...
Wireless sensor network (WSN) topology tomography is essential for routing improvement, topology control, anomaly detection and load balance. Previous studies on WSN topology tomography are restricted to static routing tree estimation, which is unrealistic in real-world WSNs due to wireless channel dynamics. We study general WSN routing topology tomography from indirect measurements observed at the...
Wireless Sensor Networks (WSNs) are being used in a variety of applications including environmental monitoring, event detection, object tracking, and healthcare applications. Network management of WSNs is one of the key practical challenges that arise from the increasing number of applications and technologies deployed. This work presents the demonstration proposal for a web-based integrated network...
This paper presents a robust distributed localization approach which employs weighted least squares scaling with soft constrains. It incorporates the a priori deployment constraints, i.e., minimum and maximum node separation among 2-hop nodes, into localization as soft constraints and penalizes pairs of 2-hop nodes whose assigned coordinates violate the minimum and maximum constraints. Combined with...
A new simulation analysis algorithms establishing wireless sensor networks communication path based on ant agorithm was proposed. The detailed design of the algorithm and implementation steps and the communication path are designed. The new algorithm is very effective to determiner multi-node wireless sensor network communication processes and has good scalability and dynamic adaptability.The algorithm...
The convergence of mashup and Service Oriented Architecture (SOA) enables the enterprise to deliver composite and situational applications by integrating information across internal and external sources. In this paper, we propose an approach that takes ideas from mashup and extend it to deliver real-time interactive visual analysis application on spatial-temporal datasets over the Internet. Four aspects...
A sensor network-based livestock farm odour monitoring system is proposed for monitoring and analyzing livestock farm odour remotely. The system utilizes a wireless sensor network built from electronic nose nodes which can detect odour compounds and environment factors such as temperature and humidity. The architecture of the system and the functionality of each component is introduced. The proposed...
