Smart City concept is a topical issue. The main contribution of this paper is the performance evaluation of topology control algorithms that can be integrated in the Smart City concept. Thus, the following topology algorithms A3, A3 Coverage and EECDS are considered. The parameters evaluated are: the number of active nodes after the topology reduction algorithm is applied, the number of packets sent...
This paper presents the measuring of the transmission power of the WSN JN5148 transceiver, operating in the 2.4 GHz ISM band (Industrial Scientific and Medical). The measurements have been conducted in a semi-anechoic chamber and were directed at identifying the transmission power and at developing the radiation diagram. The results obtained during the tests have revealed the presence of certain irregularities...
This paper presents the field testing of a street lighting monitoring and control system. The system is based on a WSN network of the large-scale type that enables the remote control of street lighting lamps. The system also enables savings in terms of the electric power and maintenance costs. The architecture uses integrated Doppler sensors that allows for vehicle detection and help complete the...
