Experimental Performance Analysis of Wi-SUN Channel Modelling Applied to Smart Grid Applications

نویسندگان

چکیده

The grid operation and communication network are essential for smart grids (SG). Wi-SUN channel modelling is used to evaluate the performance of networks, especially in last-mile communication. In this article, distribution approximation received signal strength IEEE 802.15.4g networks was investigated by using Rician curve fitting with accuracy improvement biased methodology. Specifically, applied indicator (RSSI) measurement data. With method, K-factor, a non-centrality parameter (rs), scale (?) optimized such that lower value root-mean squared error (RMSE) acheived. environments data collection selected representing location concentrator unit (DCU) meter installation residential area. summary, experimental results model parameters expanded whole range Wi-SUN’s frequency bands rates, including 433.92, 443, 448, 923, 2440 MHz, which successful multiple bands. models have improved conventional model, root mean-squared reduced percentage 0.47–3.827%. proposed could be simulation, installation, planning networks.
