| 摘 要： | 无线多跳网络的基本问题是信道交叠情形下系统容量上限的估计以及最大容量的获取.建立有实效参数的容量渐近估计模型,不仅可以准确、深入描述部分交叠信道的竞争性与互助性对系统容量的影响,而且可以为系统容量优化提供重要理论参考依据.该模型揭示,无论是单播还是广播业务,网络容量峰值的达到是可用中继节点数与发送概率的匹配,更具体地说是归一化节点密度与节点数的乘积同节点发送概率的匹配.

| Abstract: | The essential problems of wireless multi-hop networks are the evaluation of maximum capacity of partially overlapped channels communication system and how to achieve the capacity in the communication system.To establish an asymptotic capacity model with efficient and applied parameters not only could depict the competitive and coordinated features of the partially overlapped channels,but also could optimize the designation and capacity evaluation of the networks.The model in this paper shows that the maximu... |
