Firstly, this paper puts forward an improved authentication and key distribution scheme for internet environment, in which we adhibit multilevel authentication center, encryption technology of DES, RSA and one-way function to actualize the safety of communication among the different user on network and reduces the workload of the authentication institution; at the same time, this scheme can also assure the security of network. Besides, it use the temporary symbol and the responds" sign of both-side correspondent to replace time stamp and applies them to internet communication to countercheck "rebroadcast attack and accordingly resolves the problem that it needs synchronization for network clock.

本文在首先提出一种改进的Internet网络环境下的认证及密钥分配方案，该方案考虑采用了多级认证中心，DES、RSA和单向函数加密机制，实现了网络上不同用户间的安全通信，降低了网上认证机构的工作量，同时也能够保证网络的安全性；并用通信双方的临时标志和响应者标识来代替时间戳应用于Internet通信中以防止"重播"攻击，从而解决了以往需要网络时钟同步这一难题。

Packet Radio NetworkIn the network of Ad Hoc, the crunode has a report text to turn hair ability, the correspondence of crunode may pass by to have another an inside a turn of crunode hair, then has been much jump, this be the network of Ad Hoc with other move network of most basically distinct.

在Ad Hoc网络中，结点具有报文转发能力，结点间的通信可能要经过多个中间结点的转发，即经过多跳，这是Ad Hoc网络与其他移动网络的最根本区别。

For the limitations of traditional algorithms that can not be reasonably accurately predict the traffic, we have adopted BP neural network and curvilinear regression algorithms. First, we use BP neural network to train on historical data and then use the curve of regression to predict various factors, and then forecast data into the trained BP neural network which has been trained well, you can get future traffic forecasts.

针对以上传统算法的局限性，采用BP神经网络与曲线回归耦合算法，用BP神经网络对历史数据训练，利用曲线回归对各因素待测年份之值预测，将各因素的预测值带入已训练好的BP神经网络中，即可得到未来交通量的预测值。
