Wireless Sensor Network for Monitoring Maturity Stage of Fruit

In this letter, we present a wireless sensor network for monitoring the maturity stage of fruit. A dual-polarization coupled patch sensor, which is robust to environmental changes, was designed to operate at 2.45 GHz. It was attached to a Durian fruit for a period of days to measure the magnitude of mutual coupling corresponding mainly to the starch concentration of its pulp. Signal was transmi...

Security Analysis of Lightweight Authentication Scheme with Key Agreement using Wireless Sensor Network for Agricultural Monitoring System

Wireless sensor networks have many applications in the real world and have been developed in various environments. But the limitations of these networks, including the limitations on the energy and processing power of the sensors, have posed many challenges to researchers. One of the major challenges is the security of these networks, and in particular the issue of authentication in the wireles...

Wireless Sensor Network for Cattle Monitoring System

This paper describes a cost effective Wireless Sensor Network (WSN) technology for monitoring the health of dairy cows. By monitoring and understanding the cow individual and herd behaviour, farmers can potentially identify the onset of illness, lameness or other undesirable health conditions. However, the WSN implementation needs to cope with various technical challenges before it can be suita...
