| 摘 要： | 对两节点在彼此覆盖范围内的双向传输流模型进行研究.用瞬时链路状态信息的机会中继策略,选择出最佳中继节点,然后根据门限值来判断是否需要最佳中继参与协作,当两节点直连链路状态大于门限值时,节点间直接交互信息,无需中继节点的协助;反之,信源和最佳中继共同协作参与传输.相比直接传输模型,本策略提高网络吞吐量的同时,增大了系统的...

| Abstract: | We research a bi-directional traffic flows network which two nodes are in each signal coverage area's in this article.Selecting optimum relaying using opportunistic relaying strategy based on instantaneous channel state information,then judging whether needs optimum relaying participates in the cooperation according to the threshold value.Don't need relay for transmission when the direct-transmission channel state is bigger than the threshold value; whereas sources and optimum relaying cooperate together.Co... |
