为了研究一个社会群体，如蚁群，监测整个领土上发生的事件，我们提出了一个模型的网络巡逻蚂蚁从事信息收集和传播。在这个网络中，个体沿着独立的路径穿过一个区域，并在遇到时相互交换信号。蚂蚁的路径由相关随机游动描述。通过模拟和解析近似，包括一种新的方法来空间逻辑方程，我们研究的效率，这样的网络发现一个不断变化的流的“事件”分散在整个区域和信息传播到网络中的所有蚂蚁的速度。我们证明了事件发现的效率和信息传播的速度提高了网络的大小和直的个人蚂蚁路径，这两个效果相互作用。结果导致预测物种特定的运动模式，群体大小和蚂蚁生态之间的关系。
To study how a social group, such as an ant colony, monitors events occurring throughout its territory, we present a model of a network of patrolling ants engaged in information collection and dissemination. In this network, individuals follow independent paths through a region and can exchange signals with each other upon encounter. The paths of the ants are described by correlated random walks. Through simulations and analytic approximations, including a new approach to the spatial logistic equation, we study the efficiency with which such a network discovers a constantly changing stream of "events" scattered throughout the region and the speed with which information spreads to all ants in the network. We demonstrate that efficiency of event discovery and the speed of information spread are enhanced by increased network size and straighter individual ant paths, and that these two effects interact. The results lead to predictions regarding the relations among species-specific movement patterns, colony size, and ant ecology.
