PROJECT TITLE :
A Segmented Packet Collision Model for Smart Utility Networks Under WLAN Interferences - 2016
Smart metering utility network (SUN) is an emerging wireless technology for achieving intelligent control and info transfer in smart grid applications. However, the operation of SUNs on unlicensed bands is terribly sensitive to external interferences generated from alternative networks operating on the same spectrum bands, like wireless native space networks (WLANs). This paper aims to investigate packet error rate (PER) performance of a victim SUN receiver under the interferences of one or more WLAN transmitting nodes. To accommodate a situation leveraged by multiple random variables, like offset between desired SUN data packet and WLAN packet, length of WLAN knowledge packet, and time interval between 2 consecutive WLAN packets, we have a tendency to propose a segmented packet collision model with the help of the chance theory. We have a tendency to initial divide all the packets into little segments and then calculate the collision chance of each section to acquire a more correct bit error rate (BER). Then, primarily based on different BERs in distinct segments of the required SUN packet, average PER of the victim SUN receiver is obtained. Finally, the proposed analytical model is validated by simulations as an attempt to judge PER performance of a SUN receiver below the WLAN interferences.
