The MANETs (Mobile Ad Hoc Network) refers to a multi-hop packet based upon wireless network that does not require any fixed infrastructure. Each node in the network act as the base station and the packets are forwarded to the required destination. Many kinds of attack can be done on this type of networks. In this paper we have described a method to detect the wormhole attack and to secure the path of the packets from these types of attacks using delay per hop method. Wormhole attack is a dangerous attack occurring in the routing protocols in the network layer. Using hop count method we isolate the node that is the cause of the wormhole attack in the network. This method neither used the synchronized clocks nor the special kind of hardware for detecting the wormhole. In this paper will help to pinpoint the malicious node and to isolate that node from the network. The performance of the network is improved.
