Allocating Addresses in Hybrid Mobile Ad-Hoc Networks

Authors : N. Mohan and V. Palanisamy

Abstract: Mobile Adhoc Network (MANET) is a peer-to-peer wireless network that it transmits without the use of a central base station or access point. The Internet Protocol Ipv4 address allocation mechanism is the widely used address allocation technique in computer networks. Address allocation to mobile nodes is an important problem in MANET when IPv4 is used. Recently several schemes have been proposed for address allocation in pure MANET environment, but they do not consider the access requirements of mobile nodes to the global Internet. This problem has been rectified in the latest version of the Internet protocol IPv6 and it is the suitable choice for the networks in global connectivity environment. Since all networks cannot be switched to the latest internet protocol IPv6 at a stretch, there need to be a gradual switch over from IPv4 to IPv6. If one network switches over to IPv6 network environment, it will not be able to communicate with the IPv4 network environment. The application developed in this research enables IPv6 network to communicate with IPv4 network, thus easing the process of IPv4 to IPv6 conversion. This study has also consideration of the hybrid MANET where the pure MANET is interconnected to the external Internet by some gateways. For global-scope address allocation, the hybrid MANET is implemented with an address allocation scheme by enhancing the Ipv6 stateless address auto-configuration protocol. The proposed system decreases the latency of address allocation period by enhancing the Duplicate Address Detection (DAD) mechanism of the address auto-configuration protocol. The study proposes 2 types of address allocation mechanism for IPv4 and Ipv6 address groups. It is also designed to handle the interconnectivity between different types of address groups. The nodes that can allocated in IPv4 network group can be communicated with the IPv6 network group environment. This study will provide the reader with a detailed understanding of the address allocation in MANET.
