This article mainly from the start of the radio signal propagation characteristics, and connecting with the reality, according to the actual situation of some aera, the three typical environment of the topography for signal channel test and modeling is choosen. Through to the research of the zone VHF/UHF band, and a positive approach of the channel test and modeling are got.
In this demonstration, distributed consensus building is used to improve the performance of RSSI based trilateration algorithms. Specifically, the objective of the consensus is to determine the spatial centroid for a distribution of sensor nodes in a wireless sensor network (WSN). Incorporating a consensus aspect reduces the sensitivity of the objective to dropped packets, changing topologies, and...
