Wireless sensor networks (WSNs) are strongly useful to monitor physical and environmental conditions to provide realtime information for improving environment quality. However, deploying a WSN in a physical environment faces several critical challenges such as high energy consumption, and data loss.In this work, we have proposed a reliable and efficient environmental monitoring system in ponds using...
Wireless sensor networks are often placed in hostile and unattended areas, making the nodes exposed to many attacks. Node capture is one of the prominent attack in such networks. Whenever, a node is captured, its keys have to be revoked from the network by means of rekeying. We aim to optimize the problem of key revocation and rekeying by reducing the communication and computation overhead. An attack...
Wireless Sensor Networks (WSNs) are popular for their usage in various application like environmental monitoring because of their small size and ease of deployment. However, there is a considerable cost of owning and maintaining involved which might impede small to medium scale industries from availing their services. Even for large-scale industries, WSNs deployed and maintained with so much financial...
Multiple weather stations and Wireless Sensor Network (WSN) system deployed throughout the state of Perlis to monitor weather and environmental conditions. Weather data from sensor nodes hops through WSN nodes towards base station attached to embedded computer system. These data accessible by eKoView, web-based monitoring application provided. However, current system limits monitoring to local area...

As nodes appear and disappear in a Wireless Sensor Network (WSN), communication protocols acting in the data link, network and transport layers adapt dynamically to the new network structure. We present an extension of the dynamic nature of WSNs to the web via an adaptive communication protocol called the adaptive Sensor Web Language (SWL). Adaptive SWL provides a web application with a reliable mechanism...

In this study, we propose intersection collision avoidance system in preventing traffic crashes at typical urban intersections. The proposed intersection crash prevention system would display the crash warning messages to the drivers when crash-prone conditions are detected through the sensor system installed along intersection approaches. It would further change the traffic signal setting in real-time,...
A wireless sensor network can be used in a home health care system to monitor the elderly or patients with chronic diseases. The quality of security of the home health care system is an important requirement. If the security services or servers malfunction then the system itself may become compromised. We show that with multi--server protocols, even if one or more servers become unavailable or untrustworthy,...
