Ubiquitous System application in Smart Homes

Introduction

The latest advancement in technology has opened new avenues for making life safer and easier. The ubiquity of broadband connectivity has led to innovation in the housing industry known as residential gateways or smart homes. The technology is installed in the homes to automate the entire living experience, from the rest rooms to the security of the homes; everything is connected to a system making life easier, especially for the aged and physically challenged. The term 'smart-house' is utilised for a house equipped with technological advancement that endows supervising of its inhabitants &/or boosts self-reliance.

Smart mesh interface

Smart-homes entrance is characterised as a smart mesh interface apparatus established at the customer/user premises. It presents the entails for Smart-homes client to get access to the Internet services consigned to home & furthermore to get access to the diverse services suggested through the diverse intelligent apparatus established inside house. Essentially the home entrance apparatus presents the essential connectivity characteristics to endow the customer/user to exploit the benefits of a networked house. In mechanical periods, a house- entrance apparatus does the bridging/routing, protocol & address transformation between external broadband mesh & the interior home networks (glimpse number 1). It actions as a protected fire-wall, & furthermore is the focal issue for submissions like Voice/Video over IP, home automation etc. House- entrance apparatus endows the Smart-homes users to get access to their home systems & to command diverse apparatus from an isolated position through Internet.

The proposed design of Smart Home

The diagram suggested in this study, depicted in Figure. 1 consists of the configuration & control level of the R.G.W. A complete diagram of the gateway is out of the scope of this paper.

The main aim of this particular model is to let the consumer update the R.G.W with new innovations and up-grade the existing technology. The technical knowledge is given by 'configuration Agents' also called C.A that could be made a part of the gateway and could be amended in accordance with the requirement.

For instance, if the RGW is unable to provide assistance to the Session Initialization Protocol (SIP) and the consumer wants access to VoIP service, then it might get mandatory to install a SIP CA. Furthermore, it may happen that the gateway has to provide N.A.T traversal functionality for the S.I.P messages by means of an Application Level Gateway, ALG, for example. However, if the terminal is enabled with the typical STUN client (Simple Traversal of User Datagram Protocol it will allow for a transparent traversal and the ALG should be ignored. All such facilities can be easily accessed by the user if the service-giver installs it in the R.G.W right after the user gets the service.

The architecture has been divided in two levels: the Configuration Level and the Transport Level (being this last one divided in the Transport Control Sub layer and ...
