IPv6 address allocation in hybrid mobile ad-hoc networks

Abstract

Address allocation to mobile nodes is an important problem in mobile ad-hoc networks (MANET). Recently, several schemes have been proposed for address allocation in pure MANET environment, but they do not consider the access requirement of mobile nodes to the global Internet. In this paper, we consider the hybrid MANET where the pure MANET is interconnected to the external Internet by some gateways. For global-scope address allocation in this hybrid MANET, we present a new address allocation scheme by modifying the IPv6 stateless address autoconfiguration protocol. The proposed protocol decreases the latency of address allocation period by enhancing the duplicate address detection (DAD) mechanism of the address autoconfiguration protocol.
