Automated irrigation system needs weather information for irrigation control. Scattered automated weather stations (ASW) from government agencies or wireless sensor network (WSN) are used for weather monitoring purpose. Each has its own advantages and disadvantage in terms of cost to farmers and accuracy on monitoring parameters. This paper proposes a technique of real-time spatial interpolation using...

Water distribution networks require long term autonomous monitoring solutions, integrated, reliable and cost effective data transfer methods. This paper investigates the data delivery infrastructure of water distribution network sensor equipment used for network monitoring and billing of the subscribers. Water distribution network usually apply sensors to measure water flow, pressure and temperature...
Monitoring applications have been deployed throughout the years using either wired or short and long distance wireless technology. The wireless technologies itself have been developing and on increasing trends throughout the years. This study discusses on the comparison on two types of wireless technologies to be deployed in the healthcare industries for monitoring patient's vital signs, which are,...
Stock theft is a major problem in the agricultural sector in South Africa and threatens both commercial and the emerging farming sectors in most of the country. Although there have been several techniques to identify cattle and combat stock theft, the scourge has not been eradicated in the farming sector. This paper investigates how we can model cow behaviour using global positioning wireless nodes...
This paper presents the relative merits of IR and microwave sensor technology and their combination with wireless camera for the development of a wall mounted wireless intrusion detection system and explain the phases by which the intrusion information are collected and sent to the central control station using wireless mesh network for analysis and processing the collected data. These days every...

Furthermore it provides the opportunity to connect to home automation elements like EnOcean1 sensors and actuators. The goal to this project is to provide a system which can easily be installed into existing homes and therefore is...
The current paper proposes a hybrid sensor network for indoor monitoring and discusses the way both body and ambient wireless sensors are integrated into this network. A multi-level system architecture is described which relays acquired data and alerts to relevant third parties. Its main purpose is to build a system that monitors the house of a patient and is capable of collecting data from all the...
ICT technologies provides non-invasive and low cost solutions to improve safety and security in public transport vehicles for persons and freights. In this paper we consider an intelligent heterogeneous sensor network installed on the vehicle to monitor its status. The network can be remotely interrogated by operators in the command and control centre (C&C) that, in turn, can be automatically...
The most recent Wireless Sensor Networks technologies can provide viable solutions to perform automatic monitoring of the water grid, and smart metering of water consumptions. However, sensor nodes located along water pipes cannot access power grid facilities, to get the necessary energy imposed by their working conditions. In this sense, it is of basic importance to design the network architecture...
Decrease in the number of individuals of a species is an indicator of the state of biodiversity in a region. It is difficult to estimate this decline in the traditional way. We suggest to use ICT to measure this phenomenon. We propose using a distributed algorithm to count individuals in a population and to collect abiotic factors in order to characterize habitat. The first phase consists of detecting...
