摘要:协作通信技术的关键技术特征是鼓励单天线设备参与协作,通过共享其天线用以建立
虚拟的天线阵列,从而显著地提升接收可靠性。但由于受到自身处理能力,存储空间、电池
容量等各种资源的限制,网络节点若不考虑自身的资源消耗,往往因自身资源耗尽而过早退
出网络,从而在很大程度上影响无线网络性能。本文针对节点具有一定程度自私行为情况,
通过引入节点自私性指数用以表征节点的自私性程度,并在此基础上提出了一种基于节点自
私性的无线协作网络休眠模式,并将其与传统的无线网络休眠模式进行比较。通过对平均能
量节省百分率的仿真验证,结果表明,该方案在很大程度上提高了自私性程度较高节点的平
均能量节省百分率,为无线协作网络中实现资源优化配置提供参考思路。

Abstract: The key technical feature of munication technologies is to encourage
the device with single antenna to be involved in the cooperation by sharing the antenna and create
a virtual antenna array, and thus significantly improve the reception reliability. However, due to
their limited processing capability, storage space, battery capacity and other resources, the
resource work nodes always used up and exit work prematurely if their resource
consumption is out of consideration, and thus affecting the work performance to a
large extent. In this paper, the situation that the node has a certain degree selfish behavior is
taken into consideration, and the concept of the selfishness index is introduced to
