Abstract: Structured peer to peer network has fixed structure that will be formed as fixed topology. If any of the node leaves or enters in the network, topology may vary. That will lead to load failure, link failure and resilience. To overcome these issues, proposed a new architecture as Multi-Tier clustered architecture (MCA) and it has more number of networks with different topologies. That different network will be connected via cluster head and it will be formed as overlay peer to peer network. If the value of M is equal to 3, multi-tier clustered architecture connects the three different topologies such as tree, mesh and star. Each topology selects its own cluster head and that cluster head will be connected to the cluster head of other topology network. Cluster head is used to monitor the network that reduce the issues occur due to the link failure, node failure and resilience and this will maintain the topology also. Simulation results have shown that the proposed technique reduces the delay and increases the drop rate and delivery rate.
