A Mobile Ad hoc Network (MANET) is a collection of selfconfigurable mobile node connected through wireless links. Absence of central controller it is difficult to determine the reliable & secure communication in Mobile Ad hoc network. Worm hole attack that are work as to established path in between sender and receiver but if the sender has start data transmission then in that case the worm hole attacker has create a direct link, referred to as a wormhole tunnel between them, it means more of the number of trusted nodes it means higher successful data communication process rates may well expected. In this desertion we proposed detection as well as prevention technique against wormhole attack, for detection we use profile base detection technique and get attacker node information like node number, number of attack packet, attack time etc. after that we prevent wormhole attack using neighbor trust worthy base technique and secure the mobile ad-hoc network communication, through our proposal we provide secure as well as reliable communication and simulate through network simulator-2 and analyze the network behavior in attack and prevention case. General TermsWe measure the performance of network on the bases of network parameter like throughput, packet delivery ratio, throughput, routing load etc.
