In mobile network, traditional TCP will cause throughput decreasing and delay increasing, whereas UDP is a kind of trustless transport protocol, so it is very necessary to study GIOP tunnel adpter protocol-UTP implementing in Wireless CORBA.

由于在无线移动网络中，传统的TCP传输协议容易引起网络系统的吞吐量下降和时延的增加，而UDP传输协议又是非连接不可靠的传输服务。

If the un-modified standard TCP protocol is used in wireless internet, it will make unmediated judgment that loss of data is attributed to network jam as soon as the standard TCP protocol detects loss of data.

如果将标准的 TCP 协议不加改进的运用于无线网络中，标准 TCP 一旦检测到丢包现象，就会把丢包原因不加区分的归结为网络拥塞，继而引发不必要的拥塞控制。

Firstly, the model of distributed single-hop fully-connected FH-PRNs for missile systems is developed in this dissertation, which fully describes the physical and link level characteristics of the network. Common-transmitter-based spreading codes protocol and unslotted ALOHA channel access protocol are adopted, considering two types of services, i. e. Unacknowledged Data Packet and Acknowledged Data Packet.

首先，本文建立了战术导弹武器系统分布式单跳全连接跳频分组无线网的网络模型，所建模型充分地反映了网络的物理层和链路层特性，采用了公共码加发射码的扩频码协议及异步非时隙ALOHA信道访问协议，考虑了两类业务的情况，即无应答数据分组和有应答数据分组。

In order to satisfy the requirement of various space mission simulations and analysis, a standard interface and common service for access to the system resources, that is, resource access protocol, is designed, thus the independencies of resource storage manner and resource representation are realized. The design of resource access protocol introduced the object-oriented hierarchical method.
