This scheme puts the mobile embedded client nodes in campus into consideration , which have limited bandwidth , process and storage capabilities , as well as the sever nodes , which are popular and have much more powerful resources . it is an optimized scheme which is implementable and scalable 这一方式即充分考虑到了数字校园中客户节点移动性强、资源有限的特点,又考虑到了数字校园中的行政管理关系和资源应用模式,是一种可行的优化方案。
A reasonable criterion to control error of element was studied . base upon this criterion , an indicator to drive the mobile node of bce was presented . in order to improve the efficiency , an implementing scheme ( according to the distribution of strain energy density ) was suggested when to consider the fact that the high gradient usually appears only in a very local region , especially in the case of huge amount of computation 3 .在误差控制方面，提出了bezier移动节点单元法中节点移动的收敛判据，研究了节点移动的导向原理；在mathematica和fortran环境下实现了完整的计算编程；在处理高梯度问题的实际应用中，提出了高应变能密度区的局部化处理的求解方案。
Based on the idea of contention reservation access and polling transmission , user - dependent perfect - scheduling multiple access ( upma ) protocol is presented , which supports both node mobility and multi - hop network architecture . it improves channel utilization greatly and guarantees that a node accesses the channel rapidly 基于有效竞争预约接入、无冲突轮询传输的思想提出了在无线adhoc网络中支持节点移动性和多跳网络结构的依据用户妥善安排的多址接入( upma )协议。
Mobile agent is an independent program , which can migrate from one machine to another in a heterogeneous network , in order to look for appropriate compute resource , information resource or software resource and take advantage of these resources lying in the same host or network , to deal with and use these resources , delegate the user to finish the specific task 移动agent是一个独立的计算机程序，它能够在异构的网络中从一个节点移动到另外一个节点，寻找合适的计算资源、信息资源或软件资源，利用这些资源同处一台主机或网络的优势，处理或使用这些资源，代表用户完成特定的任务。
According to the principle of this new link protocol , the scheme is simulated in opnet simulation . a whole network model using dsr route protocol and this new link protocol is found . several scenarios are designed to validate the feasibility of this link protocol under the vary load and the vary node mobile speed 本文最后根据提出的链路层协议原理,利用opnet网络仿真工具实现了该短波链路层协议模块,并在此基础上使用dsr路由协议模块搭建了整个节点模型和网络模型,最后模拟了多个不同的仿真场景,给出了在不同负载及不同节点移动速度下协议及网络性能变化情况。
