\section{IoT Network Achitecture}
The
There are a lot of moving parts in the networking for the Internet of Things; a lot to sort out between WiFi, WiFi LP, Bluetooth, Bluetooth LE, Zigbee, Z-Wave, EnOcean and others.
Some standards are governed by open, independent standards bodies, while others are developed by a single company and are being positioned as defacto standards. Some are well established, others are in the early adoption stage. All were initially developed to meet unique application-specific requirements such as range, power consumption, bandwidth, and scalability. Although these are familiar issues, they take on a new urgency in IoT networks.
To begin establishing the right networking technology for any IoT application, it is important to first understand the network architecture, or the network topology, that is supported by each technology standard. The networking standards being used today in IoT can be categorized into three basic network topologies; point-to-point, star, and mesh.
The following figure illustrates these three topologies followed by a deeper discussion of each.
