Security is one of the primary issue in the Mobile Adhoc Network (MANET) particularly as for the size and complex nature of the system. The principle reason of security issues in MANET is that there is no physical connection between the nodes. This paper gives the impact of wormhole attack and discloses how to provide security to the packets with the help of Delphi technique. By applying Delay Per Hop Indicator (DELPHI), nodes which are the responsible for wormhole attack can be removed with the support of hop count method and AODV routing The metrics used for calculating network presentation are packet loss, throughput and end to end delay, which gives the better Quality of Services.
