Abstract
Network merges and partitions occur quite often in MANET wherein address auto-configuration is a critical requirement. There are various approaches for address auto-configuration in MANETs which allocate address to the nodes in a dynamic and distributed manner in which HOST ID and MANET ID are assigned on the basis of their Base value. MANET merges and partitions employing Cluster Based Routing Protocol require a node to be assigned as the Cluster Head (CH). This paper presents the Election Algorithm which assigns a node as the Cluster Head on the basis of its weight. Through simulation using the NS-2, it has been shown that the Election Algorithm improves the packet delivery ratio (PDR) significantly and decreases the packet delay to a great extent in comparison to the existing AODV protocol.

Summary
Mobile Ad hoc Network (MANET) is dependent on the wireless technology and relies on the wireless transmitting devices. There is a limitation of manual allocation of unique identifier due to random movement of nodes which leads to frequent changes in topology This issue could be overcome through the address auto-configuration approach. Any address auto-configuration mechanism should meet the following requirements: a) Topology change- In MANET’s nodes are mobile and could join and leave the network at any moment without notification. This paper considers address allocation through autoconfiguration It assigns IP addresses automatically and gives the characteristic comparison of the stateless, stateful and hybrid protocols. For handling the frequent partitioning and merging of network due to high mobility of the nodes, a hybrid routing technique named Election Algorithm for selecting Cluster Head (CH) is proposed. Paper is organized as follows: Section 2 gives the characteristic comparison on various address auto-configuration protocols.
