Home Automation, Power Lines and the Internet Quenten Alick 3.4 Server Specifications 3.4.1 Control and Receive Data from Client In order to control and receive data from the client, the power line communications medium will be used. The main requirement for this is simplicity and low cost. There is no need for a high-speed link since the adapter being designed relies on human input. In this case a response time of a second would be quite acceptable. Also, the amount of data being transferred from the client to the server is relatively small. Reliability is also not essential. Although a reliable communications link is desirable, the nature of the data being transmitted means that loss of data or corrupted data will not adversely affect the system. 3.4.2 Communications with the Internet There are many options that need to be considered when connecting a device to the Internet. For a practical home automation system, the use of a modem is likely to be the best option. However, as was mentioned earlier, the Internet Connectivity of this design is not considered to be the main focus of the thesis. For this reason, the only requirement for the Internet connection is that it be quick and simple to set up. To be able to remotely control the adapter the controller in the system will need to have a web server. The requirement for this is the ability to handle incoming requests as well as being able to update a local web page to reflect the current status of the system. - 16 -
