    ABSTRACT: Although the system of the individual purpose exists in a home, a network for home use does not exist. There are three important problems to home network realization. It is cost’s being cheap, and there being no necessity for construction, and being able to communicate anywhere in a network. In order to realize this, the network system which works simultaneously two communication systems, wireless (IEEE 802.15.4Zigbee) and wired (Power line carrier communication ; PLC ) communication, was examined .

    ABSTRACT: As the actual testing result without any countermeasure in the communication environments in the house, it has gained that the communication success rate is 82% in the current wireless type 802.15.4 and is 70% in the wired PLC, and is 90% in the dual communication system with the mutual complement of them. Moreover, in order to improve the communication quality, the routing system through the nodes is investigated. As the result, it is found that the routing system in which the features of the wireless and wired communications are considered will considerably reduce the number of the routes and the number of the communication times per route. Thus, we think that one of the methods to put the measures into practice will be gained.

    ABSTRACT: A system of simultaneously communicating of the same data in a home or relatively small home-like relatively small space using different communication methods, wireless and wired, was tried. As a result, 100% successful data communication was achieved without taking specific measures in making any changes to the communication environment. By a single means of wireless or wired communication, the message transfer success rates of message transfer were about 80% and about 70%, respectively, without changes to no particular measures taken in the communication environment, and 96% success was achieved in a mathematical simulation by the simultaneous communication method. However, the result of the above trial encouraged us to explore the find possibility of installing a network in a home or relatively small home-like relatively small space without giving making any specific improvements to the communication environment.
