Distributed Hashing Based Group Management Scheme for the Peer-to-Peer Trust Model

In recent days, computing and communication environments are extensively more difficult and disorganized than classically distributed systems over the internet, lacking any centralized organization or hierarchical control. In such case the emerging technology peer to peer overlay network is the answerable one. The peer to peer networks will provide a good layer for creating a data sharing, content delivery and optimal routing in many applications. Structured peer to peer network has a fixed structure that will be formed as a fixed topology. If any one of the nodes leaves or enters in the network, topology may vary. In such case, it will lead to load failure, link failure and resilience. a new architecture namely Distributed Hashing distributed grouping management (DHDGM) is proposed. The proposed DHDGM model uses the secure group architecture model those are processed vertically for the selection of group header. The resurces are shared between the group headers for the detection of the intruders. With the distributed grop management of the data between the network group data is transmitted in the P2P network. The simulation analysis of the proposed DHDGM model exhibist the ~4% - 7% reduced delay and packet drop rate compared with the existing ATAR and RSPP model.
