摘要: 由于具有广阔的应用前景,近年来无线传感器网得到了广泛的关注。其中,能量效率及数据延时是无线传感器网设计需要考虑的两个重要性能指标。本文中,基于排队模型,采用功率模式管理,对节点平均功耗及数据延时等无线传感器网的性能做了研究,并得到了与调制星座体积之间的关系。

Abstract: Wireless sensor networks have recently generated flurry of research activity because of variety of applications. Energy efficiency and packet delay are two important design considerations for wireless sensor networks. In this paper, queue model and power mode scheduling are used, the characteristics of wireless sensor networks, such as average power consumption and packet delay are researched, the relationship between average power consumption, packet delay and constellation size are derived.
