  • Turn your iPhone or iPad into the hub of a distributed sensor network with the help of an Arduino microcontroller. With this concise guide, you’ll learn how to connect an external sensor to an iOS device and have them talk to each other through Arduino. You’ll also build an iOS application that will parse the sensor values it receives and plot the resulting measurements, all in real-time.

If hubs or concentrators are used, it can be relatively easy to insert a new node. However, some devices are coming out with features that remember MAC addresses and can detect whether a new node is on the network.

  • This document serves as a design guide for those intending to deploy a site-to-site VPN based on IP Security (IPsec). The designs presented in this document focus on Cisco IOS VPN router platforms. The primary topology described in this document is a hub-and-spoke design, where the primary enterprise resources are located in a large central site, with a number of smaller sites or branch offices connected directly to the central site over a VPN. A high-level diagram of this topology is shown in Figure 1....
