[Show abstract][Hide abstract] ABSTRACT: Although many communication ways exist in a home, it waits these existing communication ways for the network which ties all
up. It is necessary to have three important performances in this network. They are a low price, construction needlessness,
and a high communication performance. In order to realize this, we are advancing examination of the mutual complement network
system which works two communication systems simultaneously. That is, they are wireless communi-cation (IEEE 802.15.4 Zigbee)
and wired communications PLC (Power Line Communication). This network has been evaluated at the general home or the comparatively
small-scale business building. And since the system which raises a communication performance from this time was obtained,
[Show abstract][Hide abstract] ABSTRACT: In order to improve the home network communication performance, research with two different communications, wired and wireless,
is catching researchers’ attention. We call this type of network as a mutual complementary home network. In this paper, we
discuss some reliable communication methods for the mutual complementary home network and how to implement the methods. We
developed a prototype system and evaluated the performance of one method.
[Show abstract][Hide abstract] ABSTRACT: In the future home network, information appliances will be controlled and managed by the use of PLC (Power Line Communication) that enables the No New Wire and ZigBee concepts to be implemented in a ubiquitous sensor network. However, the arrival rate of PLC and the communication quality deterioration of ZigBee are significant problems because the control information for the appliances has to be transmitted reliably. To solve these problems, we examined communication methods that increase the arrival rate in a mutual complementary network environment. These methods improve reliability by mutually complementing, through PLC and ZigBee, the places where nodes can't communicate through only one interface. A comparison of these methods through ns-2 simulations shows that the Table Creation method is more reliable than the other methods we examined.
