Design and simulation of address management protocol based on DHCPv6 for large-scale wireless sensor networks

Abstract

For wireless sensor networks (WSNs) distinguished by dynamic topology always has large number of nodes, the node's address management is a challenge issue in many WSNs application systems. Based on the basic principle of Dynamic Host Configuration Protocol over IPv6 (DHCPv6), a novel scheme of address allocation and management for large-scale WSNs is presented. Address allocation scheme based on client / server was given and the message processing of the client and server were designed. At last, the simulation experiment had been operated for verifying the availability and effectiveness of our approach through OPNET Modeler. The results showed that the protocol can rapidly and efficiently support IP addresses distributing up to 450 nodes that are covered by one server node.
