Optimized Method for Data Query In Distributed Data base 分布式数据库数据查询的优化处理方法
Energy is the most critical resource in the life of a sensor node, therefore, its usage must be optimized to maximize the network life. If each node transmits data to sink or base station directly, then it will deplete its power quickly. 节点能量管理的优化对于延长网络寿命具有重要影响,如果每个节点直接向sink节点或基站发送信息,节点电池很快耗尽,网络也会失去作用。

Whilst, the process parameters is optimized by studying the experimental data using the intelligent method of error reverse transform NN, and the results show that NN method is better than traditional one, this provides a base to real practice. 采用误差反向传递神经网络的智能方法通过对实验数据的学习来对工艺参数进行优化,结果表明神经网络方法优于传统方法,为进一步实用化奠定了基础。
