Description: 基于UDP实现简单的可靠数据传输
由于数据是在不可靠的信道上传输的，因此数据在信道上传输时可能会发生比特错误，数据丢失。Rdt3.0及之前的版本都是停止—等待协议，它限制了网络底层硬件的能力。为克服这个问题引入了流水线技术，两个能恢复流水线中的错误的基本方法：第N个分组重发和选择性重复。综上，要实现差错编码，顺序号，计时器，分组确认，滑动窗口，拥塞控制。-simple UDP based on the reliable data transmission of data is not reliable transmission of the channel, therefore the data transmission channel may occur bit error, data loss. Rdt3.0 and earlier versions are stop-wait for the agreement, which limits the underlying network hardware capabilities. To overcome this problem the introduction of pipeline technology, both of which can restore pipeline error in the basic methods : section N to a re-issued and selective repeat. In sum, to achieve error coding, sequencing, the timer, a confirmation, sliding window, congestion control.

Description: Recently, IEEE 802.16j multi-hop relay network is proposed to increase data rate and coverage of the IEEE 802.16e networks. The Relay Station (RS) is introduced to relay the data from MR-BS to SS/MS or from SS/MS to MR-RS. We have studied the research area for a whole, and we proposed some improvements that could decrease the congestion opportunity of non-transparent RS using distributed scheduling. We have to modify the NIST WiMAX module which is implemented under the NS-2 in order to test the correctness of our proposed scheme. Subversion and Google-code-hosting are used to manage the project versions, thus we could be easy to modify the NIST module to support the functions of RS.

Description: 在电力市场改革的过程中，出现了许多新的问题：网络潮流的分布主要由电力交易 的分布所决定，电力交易以追求最大利润为目标，于是出现了电力系统中输电价格较低 的线路或电能价格较低的发电机组周围的线路负荷过重，从而增加了发生阻塞的可能 性。本文就电力市场中输电阻塞管理的办法以及阻塞费用的计算进行了讨论。-the electricity market reform process, the emergence of many new issues : the trend of the distribution network mainly by the distribution of power transactions by the decision to pursue electricity transactions for maximum profit, so a power system transmission lines with lower prices or lower the price of electricity generating units around the line overloading, thereby increasing the possibility of obstruction occurred. This paper on the electricity market transmission congestion management methods as well as obstruction of calculating the fees were discussed.
