Summary

We have successfully implemented a tentative prototyping with low cost to verify our proposed eHome system. The prototyping is satisfactory and confirms to the minimal requirement of the future home system. The current prototyping have integrated with multiple technologies and systems including multiple home network interfaces and systems, and other network technologies as shown in Figure 6.1 Besides we have

integrated HTTP and WAP into current eHome system to provide the remote access capability. Hence, we can using WAP-enabled portable device to connect our eHome RG via HTTP protocol to access any service provided by home appliances of eHome system when we outside house. Moreover, we have integrated portable devices to support the remote capability inside home. Now users are able to control the home appliances through BlueURC, the portable device with friendly user interface and BlueTooth, whenever they are at home.

6.2 Future Work

Although we have implemented a tentative prototyping of eHome system with many technologies, but there are still some problems needed to solve. For instance, we just integrate one existed home system - X10 system into the current prototyping, but different home systems will cause different issues and implementation approaches.

Perhaps, it is necessary for us to add more software components to eRC.

Moreover, the current prototyping does not support the multimedia service. We plan to support the multimedia service by integrated with HAVi home system. HAVi is a home system dedicated to support multimedia services for AV equipments based on IEEE 1304 network. To integrate HAVi into eHome may cause many unknown issues.

Some related researches [84][85] devote to propose the suitable solution for these issues. For example, [84] proposes a gateway-based architecture, which integrates with IEEE 1394 network, a popular home system in Japan, and Internet, to support the capability of remote access of multimedia services.

The current prototyping does not support the multimedia service. Therefore, we intend to integrate a multimedia home system - HAVi with current prototyping to provide the capability of multimedia services in the future. Besides, we also try to implement a more complete and convenient mechanisms for eURC. For instance, we can implement a mechanism to support java program downloading. Thereby, we can download the needed java control program according what kind of services of home appliance we want to access through potable device wherever you are. Moreover users are able to access the service instinctively due to the java control program with friendly user interface. Some related researches are proposed recently. For instance, [82] has proposed a great scheme, the autonomous and generic remote control scheme

and implemented a prototyping, the generic remote controller (GRC), successfully.

GRC utilized XML as representation of service control user interface. Such scheme is appropriate to be the future implementation of eURC due to XML is the popular markup language for documents containing structured information. We will strive to overcome the problems described above in the future.
