In recent years, voice over Internet Protocol (VoIP) has gained much attention in wireless local area networks (WLANs). Although IEEE 802.11e has been standardized to provide voice traffic with quality of service (QoS) support, the voice quality will still be severely degraded with a large amount of best-effort traffic generated by distributed coordination function (DCF) or enhanced distributed channel...
AMR (automatic meter reading) and PQ (power quality) management based on kinds of network technologies has become a trend. However, because of the high construction and maintenance costs with the existing meter reading technology, the applicability to different residential buildings and different network infrastructure should be improved, it is greatly significant to research new kind of power meter...
This paper analyzes the basic and RTS/CTS and fragment MAC access mechanism of IEEE802.11 DCF (distribution coordination function), and puts forward the model of wireless distributed measurement system (WDMS). It analyzes the elements that affect system real-time communication. It sets up the simulation network scenario of real-time communication through software, then simulates to research the MAC...
