Enabling QoS in stateful auto-configuration protocol used in IPv6 based manets

The Mobile Ad-Hoc NETworks (MANETs) is an easy deployable, infrastructure-less networks. In IPv6 based MANETs the address configuration is done either with a stateless mechanisms or with the help of server like Dynamic Host Configuration Protocol version 6 (DHCPv6). The DHCPv6 server initially resides on the node which acts as the Internet gateway (IGW) in the network and later on each of the configured nodes will become a server. The node which enters the network, will request for an IP address and the server distributes a unique IP address and an address pool. Formerly the new node identifies the server using a random selection algorithm and this method faces many QoS issues due to the usage of the random selection algorithm. The proposed technique addresses the issues using a QoS enabled algorithm, which reduces the address acquisition delay and packet drops in the network, and thereby enhancing the performance of the network. The proposed technique is simulated and compared with the random selection algorithm using Network Simulator Version 2 (NS2).
