Reliable Communication Methods for Mutual Complementary Networks

摘要

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.
