According to the energy efficient requirements and characteristics of HDRWSN, a Load Balanced and energy aware routing protocol considering both energy consumption status and load congestion levels of sensor nodes has been proposed. LBEAR protocol equipoises network energy and load distribution, therefore, it can prolong the lifetime of HDRWSN through resource equilibrium.

根据高数据率无线传感器网络的能量高效需求和大数据量的特点，本论文提出了一种新型的LBEAR(Load Balanced and Energy Aware Routing)协议，LBEAR协议综合考虑了节点能量消耗状态和节点的负载拥塞程度，均衡了网络能量分布和负载分布，通过均衡网络资源延长了网络生存周期，从而提高网络的节能特性。

An improved shceme for the old double-way authentication access control scheme based on Harns digital signature is proposed. The new double-way authentication protocol of the improved access control scheme can prevent man-in-the-middle attack and replay attack. After strict formal analysis with BAN logic, the result have proved that the authentication protocol is secure. The improved access control scheme is realized by the mode of single-key-lock-pair. Under new access control scheme, user can own several kinds of access right upon one file under the new scheme without the supposition that the access rights is increase by degrees, and the possibility of overflow problem is significantly reduced by our new method

作为对原双向认证访问控制方案的改进，改进后的双向身份认证协议可以很好的抵抗中间人攻击和重放攻击，经过严密的BAN逻辑形式分析和论证，结果表明该协议是安全的；改进后的访问控制方案用单钥-锁对方案实现，除保持了一般单钥-锁对方案的良好动态特性外，在不需要访问权限递增假设下，实现了用户对文件的多种访问控制权限，并大大减小了溢出问题的发生可能

W-CDMA is a notably slower, though in this country still reasonably adequate, protocol, offering a maximum of 384 Kilobits/second download speed, with some updated protocol extensions available allowing up to 2 Megabits/second.

W-CDMA是一种速度相当慢的协议，尽管在这个国家仍然是足够了。它提供最高384千位/秒的下载速度。通过一些升级协议的扩展，可以允许提高到2兆位/秒。

On the basis of the LEPS flat protocol along with TinyOS, the prototype-system implements a clustering route protocol and a wavelet data compression algorithm with run length encoding.

The Precision Time Protocol of the IEEE 1588 protocol provides an effective technique to synchronize the master clock and the slave clock.

IEEE 1588协议的精密时间协议提供了一种网络控制系统中主从时钟交换报文达到时钟精准同步的有效方法。

That NDIS mesosphere driving technology acts under protocol layer, above physical network card driving layer, has nothing to do with protocol and entirely intercepts and captures network envelops are the reasons why SSL VPN has more powerful function of supporting non-web applications.

基于SSL虚拟通道的VPN技术是未来SSL VPN发展的一个方向，是多种VPN相互融合解决本身所不能解决各自问题的一种方案，是未来VPN技术发展的一个重要方向。

To realize that, the thesis studies the PHS short message gateway protocol in detail which is the protocol to connect short message sending systems with the PHS short message gateway. The thesis also studies the client programming package which is based on SMGP and provided by the short message gateway. Using the API interface functions of this client programming package and the multiple thread mechanism, the key module — short message receiving and sending module is implemented.

为此本文详细研究了用于短消息平台接入的小灵通短消息网关通信协议和短消息网关提供的用于短消息平台开发的基于SMGP协议的客户端开发包，利用这个客户端开发包的API接口函数，并运用多线程机制，编程实现了这个短消息平台的关键模块——短消息收发模块。

First, the stations'timing process and the slot aligning are discussed. Second, the dissertation propose a resource request random access method based on feedback. The performances of this method are analyzed. Third, proceed from the considerations of the MAC protocol for the HFC system, a QOS-oriental scheduling algorithm for the MAC protocol based on dynamic TDMA is proposed. Simulation results show that the performance of this algorithm is better than that of the first come first service. Forth, two contention resolution algorithms ----p-persistent CRA and tree CRA, which are usually adopted in the HFC system, are summarized. The delay and characteristic are compared. At last, the dissertation introduces the function implementation of the MAC layer based on COM21 UPSTREAMS.
