无线传感器网络通常基于全方位感知和通信模型。相比之下，在本文中，我们研究传感器网络的方向感测和通信能力。由于其独特的特性和对网络覆盖和连通性的潜在影响，需要新的分析和解决方案。为此，本文分析了部署策略，以满足给定的覆盖概率的要求与定向传感模型。此外，对于具有定向通信模型的传感器，我们提出了检查和修复网络连通性的方法。我们设计有效的协议来实现我们的想法。一组实验也证明了我们的解决方案的有效性。
Wireless sensor networks are often based on omni-sensing and communication models. In contrast, in this paper, we investigate sensor networks with directional sensing and communication capability. Due to the distinct characteristics and potential effects on coverage and connectivity of the network, novel analysis and solutions are demanded. Towards this end, this paper analyses deployment strategies for satisfying given coverage probability requirements with directional sensing models. Moreover, for sensors with directional communication model, we propose methods for checking and repairing the connectivity of the network. We design efficient protocols to implement our idea. A set of experiments are also performed to prove the effectiveness of our solution.
