摘要：Mobile ad-hoc networks are set of nodes deployed in mobile situation. It may deploy into two states either in static situation or in mobility state. Due to low weight and mobility feature they can easily relocate and move from one place to another location. A mobile node consist the certain basic elements which can be listed as battery, transmitter, receiver and process for establishment of networks. A wireless communication is used to send and receive information among nodes. Due to wireless communication media does not imply any infrastructure and gives a structure free topology. Mobile nodes and ad-hoc network have several features and can suitable for various applications like military surveillance, disaster management, rural and jungle areas etc. Subsequently, it also have certain loopholes can be listed as resource constraint, security issues, routing overhead and network breakdown.Security is one of the major concern and also the limitation with ad-hoc network. It address that privacy is one of the important requirement into every communication. The work conclude that several security threats like wormhole attack, black-hole attack, gray-hole attack etc. are the severe security threats which not only disrupt the network but also degrade the network performance.The complete work observes that gray-hole attack is one of the severe security threats which not only try to get beneficial of vulnerability in routing protocol but also drop packets respectively. This research paper investigates the impact of gray-hole attack and also derived a mechanism to overcome it.NS-2 simulator has been used to simulate and evaluate the performance of proposed solution
