In a Wireless Sensor Network (WSN), nodes are battery powered and then they are energy constrained. Network lifetime is the most important characteristics of performance for these networks. In this paper, we propose routing protocols that take into account the battery residual energy in sensor nodes and the energy required for transmission along the path toward the sink, which allows the distribution of energy load among the whole network nodes. Simulation results show that the network lifetimes increases up to 50% for the first node die and up to 114% for the last node die over comparable schemes like MLER protocol.

Case Study: Liz Bagshaw on the IRC sensors
Our infrared IR’C sensors have been making waves in the world of glacial meltwater monitoring. Glacial environments are key indicators of global warming and climate change. They’re also home to a diverse range of microorganisms. Both of these need to be quantified and monitored, but doing this isn’t easy because of the cold, remote environments in which they are found. To combat these challenges, Dr Liz Bagshaw, Lecturer in Earth and Ocean Sciences at Cardiff University, has been conducting...
SeNsiM-SEC: secure sensor networks integration to monitor rail freight transport
In recent years, the interest in monitoring infrastructures has spread in many application domains, even because of the number of natural disasters and terrorist attacks. This important activity can be seen in the general context of critical infrastructure protection, such as the freight trains meant for hazardous materials transportation. The design of these systems must answer to several issues: low-cost, easiness of installation, interoperability of information sources, security requirements. The use of...

Wireless Greenhouse Monitoring and Control
CAS DataLoggers Provides the Intelligent Automated Solution A fruit crop experiment station needed to remotely monitor and control its climate systems in a number of greenhouses. The proposed system needed to monitor soil moisture content and temperature and actively control irrigation and airflow by opening and closing windows to ensure that the appropriate temperature was constantly maintained. Full automation was required to minimize the manual workload, up to the point where data collection had to be automated...
