A new network routing algorithm is proposed, which follows calculation rues of logic algebra and calculates routes with depression of order transformation of incidence martrix. For network with m nodes, m-2 times depression of order transformation operations can get all routes between two nodes. Furthermore, it accords with the communication transmission rules and avoids the close loop routes.

提出一种网络路由新算法，是按照逻辑代数运算规则，以关联矩阵降阶变换方式计算，对于有m个节点的网络，只需m-2次距阵降阶变换运算，就能够算得网络两节点间全部路由，且不会出现闭环路由问题，完全符合通信传输规则。

For example,the maintenance of multiple networks can require additional staff.often,this staff must be trained on multiple vendor technologies,sometimes requiring parallel groups specializing in each （72） hence,additional maintenance procedures must be maintained and administrative records are （73） the duplication of trasport facilities to carry （74） network traffic is an inefficient use of resources and,not surprisingly,more technologies installed in a central office mean the necessity for more physical space,and an increase in power connections and power consumption.migration of these （75） network elements to IP-based DCns is alogical strategy

例如，维护多个网络需要增加工作人员。通常这些人员必须培训，以便熟悉多种制造商技术，同时还需要熟悉不同平台的许多工作小组。因此，额外增加的维护过程使得各种管理记录激增。承载着不同网络通信的多种传输设施造成了资源的无效使用。很自然的推论就是，更多的技术装置配备在交换局中意味着需要更大的物理空间，增加了动力设备和电源消耗。这些遗产网络元素逐步迁移到基于IP的DCN是符合逻辑的策略。

With the development of computer and communication technology, it is more and more indescribable that the people's demand in the Internet, so the more and the better control mechanisms which could smooth the network act very important actions, the congestion control is one of the crux, that is how avoid or eliminate the congestion in the network availability, so as to the network runs in the best and the low-grade congest state basically.

随着计算机和通信技术的发展，人们对Internet的需求已经越来越超乎想象，因此更多、更合理的控制机制对现有网络的顺畅运作起着非常重要的作用，其中最基本、最关键的就是拥塞控制，即如何有效防止或消除网络出现的拥塞，使网络基本运行在轻度拥塞的最佳状态。

Network congest can make network communication quality drops not only, still can affect the QoS of service quality standard of the user, still can affect network safety even.

网络拥塞不仅会使网络通信质量下降，还会影响用户的服务质量水平QoS，甚至还会影响到网络平安。

A major challenge of the heterogeneous wireless networks is how to jointly utilize the resources of different radio access technologies in an efficient manner. Because of the different system capacities of BS/AP and ununiformity of traffic distribution in different cells, quantities of new calls may be blocked in the overloaded cell in some hot spots; whereas its neighboring under-loaded BS/AP have superfluous bandwidth. In order to raise resource utilization of heterogeneous networks, several novel load balancing strategies are proposed, which combine the call admission control and multi-hop routing protocol of ad-hoc network.

异构无线网络的主要挑战是如何高效利用各种接入网的无线资源，针对异构无线网络基站或AP的容量差异及业务分布不均，导致通信热点地区的新呼叫因负载过重大量阻塞，而相邻轻负载小区却有容量盈余的现象，本文提出了几种联合呼叫接纳控制及ad hoc网络多跳路由算法的负载均衡策略，以提高整个异构网络的资源利用率。

After the direct communication is established, the network system monitors continuously the communication signal between these two mobile terminals for receiving outburst, demodulates outburst to determine whether the outburst contains the control information for the network system, and execute corresponding function if the outburst contains.

网络系统对接收到的在两个移动终端之间通信的突发进行解调，以确定接收到的突发是否包含欲用于网络系统的控制信息。如果在接收到的突发中包含欲用于网络系统的控制信息，网络系统将执行相应的功能。

Firstly, the SPN model for a single-layered LEO satellite network under half duplex mode is constructed. Then, average time delay is chosen as a key performance index to evaluate the network performance of the constructed SPN model with SPNP 6.0 software. Furthermore, the effects of arrival rate, network load, message number on average time delay are also analyzed.
