Comparison of DP Effects in MANET AAPs with Link Error

A MANET consists of a set of mobile nodes where mobile nodes have routing capabilities to forward packets. Each mobile host becomes a member of a self-organizing wireless network, where one another communicate over multi-hop wireless links, without relying on a fixed communication infrastructure, such as a base station or an access point. It is essential that all nodes are able to perform the operations required for the configuration of unique addresses to execute proper routing of data packets in a MANET. Address auto-configuration is an important issue, since address pre-configuration is not always possible in MANETs. MANETs currently depend on checking the IP addresses of nodes to decide if the connection and identification of nodes participating in a MANET are established. In conventional networks, address auto-configuration is categorized as either a stateless or a stateful protocol. When a network is not especially required to control the exact IP address assignments if the addresses are unique and routable, the stateless approach is used. In contrast, the stateful approach is used when a network demands exact IP address assignments. Dynamic host configuration protocol (DHCP) is an example of a stateful protocol, where a DHCP server assigns unique addresses to unconfigured nodes and keeps state address information in an address allocation table. However, in stateless protocols, a node can select an address and verify its uniqueness in a distributed manner using DAD algorithms. Using DAD algorithms, a node in a MANET, which lacks an IP address in the MANET, can determine if a candidate address it selects is available. A node already equipped with an IP address also depends on DAD to protect its IP address from being accidentally used by another node in the MANET. Based on the conventional method [1], DAD can be classified as Strong DAD and Weak DAD. Strong DAD uses an address discovery mechanism, where a node randomly selects an address and requests the address within a MANET, checking if the address is being used in the MANET. Based on a reply to the claimed request, which needs to arrive at the node within a finite bounded time interval, the node can detect address duplication in the MANET. Weak DAD is proposed, where ad hoc routing protocols are used to detect address duplication by modification of the routing protocol packet format. MANET routing
