Wireless Sensor Networks for Smart Cities

每天都有更多基于计算机的设备连接到互联网。这些设备中的大多数至少有一个传感单元，为物理世界和基于计算机的系统之间的直接集成创造了机会。这就是物联网(IoT)和智慧城市(Smart Cities)背后的理念--这是互联网的一种发展，在这种发展中，日常物品具有网络连接，允许它们发送和接收数据。想象一下，在一个城市，路灯实时遵循交通要求，工厂和汽车的空气污染通过使用来自微小、廉价和节能的传感器的数据来控制。在不久的将来，无线传感器网络有望集成到物联网中，从而集成到智能城市中。传感基础设施在智能环境中发挥着重要作用，也带来了巨大的研究机会。传感器节点可以动态接入互联网，利用互联网进行协作，完成各自的任务。未来的互联网被设计为物联网，预计将是一个基于标准通信协议的可唯一寻址的互联对象的全球网络。传感器将在智能城市中发挥关键作用。绿色城市，从城市野生动物倡议到城市农业和绿色交通网络，公民感知和智慧城市项目正在涌现，试图通过更大的城市连接来实现更好的可持续性。

Every day more computer-based devices are connected to the internet. Most of these devices have at least one sensing unit, creating opportunities for direct integration between the physical world and computer-based systems. This is the idea behind Internet of Things (IoT) and Smart Cities - a development of the Internet in which everyday objects have network connectivity, allowing them to send and receive data. Imagine a city where the street lights follows the traffic requirements in real-time and the air pollution form factories and cars is controlled with the use of data coming from tiny, cheap and energy efficient sensors. In the near future, Wireless Sensor Networks (WSNs) are expected to be integrated into the IoT and consequently to smart cities. The sensing infrastructures have a major role in smart environment and great research opportunities. Sensor nodes can join the Internet dynamically and use it to collaborate and accomplish their tasks. The future Internet, designed as an IoT is foreseen to be a world-wide network of interconnected objects uniquely addressable, based on standard communication protocols. Sensors will have a crucial role in smart cities. Green cities, which span from urban wildlife initiatives to city agriculture and green transport networks, citizen sensing and smart cities projects are emerging that attempt to realize improved sustainability through greater urban connectivity.
