A DHT-Based Networking and Addressing Method in the TCP/IP Building Intercom System

In the TCP/IP building intercom system, broadcast addressing or query-list addressing are often used to obtain the IP address of the called party. However, these methods are limited by the function of the network equipment, intolerable resource costs, and high failure rate of querying. To solve such problems, this paper presents a networking and addressing method in the TCP/IP building intercom system which is based on Distributed Hash Table (DHT). Results from theoretical analysis and simulations show the feasibility and superiority of such a method.
