The original Fischer-Huber loading algorithm attempts to minimize the probability of bit error by maximizing the signal to noise ratio. Bits are allocated to achieve the same error probability in each of the used subcarriers. However, in channels with a high difference in attenuation like access Power Line Communications (PLC) channels, this could result in overallocation for parts of the subcarriers,...
In order to improve communication reliability of power line carrier sensor network, a network topology dynamic discovery algorithm based on improved ant colony algorithm is proposed. The network topology discovery issue is changed into the minimum spanning tree of map by optimization strategy which based on antspsila election roads. Moreover, the idea of depth-first search is combined with to ensure...
