In recent years Mobile Adhoc Network is developing as an important technology in wireless networks.It showing quick progress and has many applications.These types of networks provide strong and fast data delivery to users in wireless network.In WMN routers use advanced antennas to transmit data to each other in multi-hop manner.In MANET, it is easily to attacks because of dynamical changing of network topology, more centralized monitoring, management point and co-operative algorithm.The important fact in mobile adhoc network is security which being accepted by many people.The major problem of MANET is selfish node.Selfish nodes in MANET do not participate in forwarding packets.Due to Some misbehavior reasons a node can be identified as selfishness or malicious.Node selfishness may be a reason to which causes minimum delivery ratio of packet and data loss in the network.In MANET network, node failure is a reason for high end-to-end delay.In this paper we propose chord algorithm to overcome these issues, chord is structured peer-to-peer protocol.To provide P2P Nodes Service in Mobile Adhoc Network Chord is applied in MANET.The major advantage of Chord algorithm is greedy forwarding, aggressive update, passive bootstrapping and overlay broadcasting.Chord in MANET might be efficient, because it is not only providing direct routing but also provides indirect and key based of overlay routing.Our proposed system suggests that Chord technique can outperform in random routing in conventional way.Key words-MANET,
