Wireless sensor networks gain ground rapidly due to their potentially low cost. These networks, including variants with UWB (ultra-wideband) physical layer, can be utilized extremely well for positioning because of the technological capabilities. However, the accuracy of localization based on the measurement of time depends on the usage of timestamps provided by certain elements of the network. This...
Optimization of wireless smart metering systems requires an entirely different approach compared to traditional communication networks. For devices operating without external power supply energy efficiency is a key factor, because it will determine the duration of operation time without external intervention. The data packets are less sensitive for delay, hence it is possible to wait for more measurement...
In wireless smart metering optimization for energy efficiency is indispensable, because in case of systems without external power supply, battery life is a key factor regarding the usability of the whole system. Sensor networks are less sensitive for delay, this is why aggregation of packets is possible. The aim of this paper is to determine analytically the amount of meter records to aggregate in...
