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...
The evacuation of a building during an emergency situation, such as a fire, is a complex and challenging task. As the conditions inside the building change due to the spreading of the hazard, it becomes difficult for an evacuee to find the best evacuation path. Information systems can prove beneficial for the evacuees, as they provide them with directions regarding the best path to follow at any given...
In this paper, we propose a robust STBC transmission scheme to combat the timing synchronization errors over frequency-selective multiple-access channels. First, the equivalent channel model in the presence of timing synchronization errors is derived and we find that the synchronization errors result in an equivalent channel model with larger number of correlated channel taps. Based on this correlated...
