Transceiver-free object localization can localize target through using Radio Frequency(RF) technologies without carrying any device, which attracts many researchers attentions. Most traditional techno
In this study, an improved random access(RA) scheme for Machine-to-Machine(M2M) communications is proposed. The improved RA scheme is realized by two steps. Fir
Due to the shared nature of the wireless medium, the performance of wireless sensor network is often limited by both internal interference and external interfer
