In this paper, we analyze the properties of effective coverage of the two-node team. Radial attenuation disk model is adopted for the individual model of coverage which conforms to the natural characteristics of devices in the real world. For any point in coverage overlapping regions of multiple nodes, based on the superposition principle, its coverage intensity equals the sum of individual coverage intensities, which complies with the collaboration behavior of output (influence) coverage applications. General properties of team’s effective coverage, including its region connectedness, and how it is related to the separation between the two nodes are first studied, followed by numerical analysis and simulations on the relations between nodes optimal separation and three different types of models.

在本文中，我们分析了双节点团队有效覆盖的特性。覆盖的个体模型采用径向衰减盘模型，符合现实世界中设备的自然特性。对于多个节点覆盖重叠区域中的任意一点，基于叠加原理，其覆盖强度等于单个覆盖强度之和，符合输出（影响）覆盖应用的协同行为。首先研究了团队有效覆盖的一般性质，包括其区域连通性，以及它与两个节点之间的分离度如何相关，然后对节点最优分离度与三种不同类型模型之间的关系进行数值分析和模拟。
