The sudden leakage of dangerous chemicals emergency decision system can help the government, chemical accident emergency rescue center, fire fighting and the units of production, transportation, storage or use for dangerous chemicals generate maneuverable emergency rescue plan in the shortest time according to the geographical location and the specific situation of the accident. The system owns the...
Energy consumption of wireless sensor networks has always been the focus of people's studies. The introduction of data aggregation reduces the energy consumption of nodes to some extent, which can be combined to reduce the need for redundant data transmission of data packets thereby reducing the number of nodes in the energy consumption. Based on the comparing of current protocols of building aggregation...
Base on energy-efficient filed data transmission system and 8b10b modulation code, this paper discusses a hard correlation frame sync algorithm. This algorithm can get the performance similar to maximum likelihood algorithm, and has advantages in energy, complexity and realization with programmable logic. Finally, the algorithm is realized by Very high speed Hardware Description Language (VHDL) in...
