H Ierarchical R Outing with S Ecurity and F Low C Ontrol

For existing hierarchical network, the network is partitioned into smaller networks where each level is responsible for its own routing but no security and flow control mechanisms has been provided while routing the information, i.e. there is no investigation of ensuring security for hierarchical network routing. Hierarchical routing is used in internet routing such as OSPF. This paper proposes a method of providing both Security, Flow control and Routing analysis for Hierarchical Network Routing using Private Key Encryption and flow control mechanism to minimize packet loss. Joint analysis of Security, Flow control and Routing is used as it reveals the weaknesses in the network that remain undetected, when Security, Flow control mechanisms and Routing protocols are analyzed independently. A simulation result demonstrates the effectiveness of the proposed method in terms of delay, throughput.
