A SECURE ADDRESSING SCHEME FOR LARGE-SCALE MANAGED MANETS

By Admin on

SECURE ADDRESSING

                              It represents a low-overhead identity based distributed dynamic address configuration scheme for secure allocation of IP addresses to authorized nodes of a managed mobile ad hoc network. A new node will receive an IPaddress from an existing neighbor node. Thereafter, each node in a network is able to generate a set of unique IP addresses from its own IP address, which it can further assign to more new nodes. Due to lack of infrastructure, apart from security issues, such type of networks poses several design challenges such as high packet error rate, network partitioning, and network merging. Our proposed protocol takes care of these issues incurring less overhead as it does not require any message flooding mechanism over the entire MANET. Performance analysis and simulation results show that even with added security mechanisms, our proposed protocol outperforms similar existing protocols.


A SECURE ADDRESSING SCHEME FOR LARGE-SCALE MANAGED MANETS

                                  A Mobile Ad Hoc Network (MANET) is a self-configuring infrastructure-less network of mobile nodes connected by wireless links. Each node in a MANET is free to move independently in any direction, and will therefore change its links frequently. Nodes that are within each other’s radio range can immediately communicate, while nodes that are not in each others radio range communicate via intermediate nodes where the packets are relayed from source to destination. Manual or static address configuration in most cases is inapplicable as the nodes in MANET are highly mobile leading to partitioning/merging of networks. Therefore in this type of network a distributed approach is a prime requirement so that a node can obtain an address dynamically from the network. Mobile ad hoc networks can be pure (open) or managed. Pure (open) MANETs are formed without any pre-arrangements or pre-requirements. These ad hoc networks are formed spontaneously and are self-organized.
