 The web of things, internet of things, how they can provide services to the users on the web is very interesting. Let's look at a scenario, particularly our smart home, which is going to have certain services, which can be tailored, which can be revoked, provisioned, built, and then we are going to identify interesting requirements that we'll discuss in due course of time. So we call it the smart home scenario. We look at how a smart home offers services through the WOT service model. First of all, as in WOT, all the interfaces are based on HTTP, understood. But the possibility of having the proprietary protocols and the broker based protocols makes the WOT service model more powerful. As a consequence, the cost is these possibilities allow or trigger certain degrees of service qualities and traffic patterns. It means that we are going to expect non uniform and heterogeneous or traffic behaviors and the service qualities which are coming for different applications on WOT from our different physical devices. So what are the WOT devices as in smart home starting off from the very basic things such as electric heater or gas based heating system with access to the room heating or the water heating like geysers. Then we've got HVAC, the humidity ventilation air conditioning. We have the entertainment system like LED TV. We have the entire household lighting system, including the lights of every room, even down to the refrigerator and microwave oven lights. Then we have cooking system, including the oven, the cooking range. Then we've got surveillance cameras deployed across different ends of the household. Then we've got the management of the main gate, the front door and the wall mountings, including paintings and the pictures of family on the wall. Then the vacuum cleaning system. In this case, we can think about a smart robot, which cleans only the relatively dirtier places over the last 24 hours. Then we've got the temperature control system of the entire house depending upon what is the temperature outside. We always had such systems like we had the Honeywell system or we have the Nest system provided by Google. So if you look at these two protocols or these two technologies which are offered there in the market, you'll see that one of them is heavily proprietary while the other is based on the internet infrastructure. So the WOD services are respectively created for all these things. For example, we need to have entertainment system, entertainment service, the heating service, heating, cooling service. Then we've got the lighting control system. We've got the visitor presence service on the main gate and the front door that works in collaboration with the cameras. So we can think about the smart home as a very interesting, intertwined set of services. So at the device layer, we've got the devices themselves. Then we have the broker. The broker comprises the adaptation layer and the service layer. So you can see that we've got the surveillance service and refrigeration service. Now these services are accessed, edited, manipulated through an app. This could be an Android or iOS app. So having such a complicated scenario means that we are not talking to the house alone. We are talking to certain power generation company, certain gas provisioning company, some security system or the security infrastructure. We are talking to the weather forecasting website. So it means that the smart home application is a very good starting point to look at the requirements. For instance, who owns what and who gets to have access to what data type and what kind of traffic pattern would be generated. Then how are you going to manage the pricing of it? How are you going to monetize it? How are you going to deliver it? And how would you see that certain quality service parameters are met? And are you going to charge it in a certain pre-paid, post-paid model? Are you going to offer certain subsidized bundles? And what is going to be your billing mechanism? How are you going to actually collect money from the service consumers? So now the smart home scenario sets the right basis for further discussion and follow up on the charging, rating, the business aspects for the IoT environment.
