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. Platform: |

Description: 论文摘要(本文首先介绍了802.16 Mesh模式下的MAC帧结构，然后对协议中的协同分布式调度机制进行了详细的阐述。根据协议的规定，在NS中编写了新的MAC层源代码，对802.16的MAC调度进行了仿真，实现了Mesh模式下协同分布式MAC调度过程，并对三次握手过程、数据子帧minislots分配成功率和minislots利用率进行了分析) 有利于我们学习-Abstracts (This article first introduced the 802.16 Mesh mode MAC frame structure, and then the agreement of the collaborative distributed scheduling mechanism in detail. According to the agreement stipulated in the NS in the preparation of a new MAC layer source code for 802.16 the MAC scheduling simulation to realize synergies Distributed Mesh mode MAC for the activation process, and three-way handshake process, the data sub-frame and the success rate of minislots allocated minislots utilization analysis) will help us learn Platform: |
