To enhance security common keys between neighboring nodes, during phase, our uses lightweight hash function to generate several by hashing unique every node sequentially in trusted base station. These construct pool keys. During pairwise...

A precise calculation method of absolute phase angles and stable power frequency is presented in this paper. Firstly, the angle positive sequence voltages/currents relative to 1 PPS (1 pulse per second) from GPS calculated by using discrete Fourier transforms (DFT). Then a most direct measurement excursion /spl Delta/f proposed every directly. The main point algorithm that sampling number period fundamental signal can be considered as reciprocal nominal for angle-1PPS. here not only obtains...

Traditional information retrieval systems have several shortcomings in common, such as delaying updating, costing additional host and network resources, so on.
