Nowadays wearable sensor devices are a growing industry field. Smart gadgets like fitness trackers monitor sport exercises and daily movements of the wearer. Sensor data is wirelessly transferred to smartphones and processed by sports and fitness apps. Depending on the application, a single sensor might not be sufficient. In ubiquitous computing, sport science and medicinal appliances, complex scenarios...
Event-triggered wake-up, in which sensor nodes wake up to work in the presence of some pre-defined events, has been widely used in wireless sensor networks (WSNs) to save energy while still completing the tasks required. However, some recently emerged domain-specific WSN applications such as structural health monitoring (SHM) and volcano seismic tomography, have different requirements with regard...
A novel communication protocol - Adaptive Transmission Power Protocol - for Wireless Sensor Networks with the facility of reconfiguring the transmission power of the hardware is presented. Specifications of the protocol including the packet format and the contention avoidance methods are described. The protocol is implemented on a hardware platform and the performance is considered for a fundamental...
