A Review: Security Issues in Mobile Ad Hoc Network?

Mobile Ad-hoc network is infrastructure less, spontaneous and multi-hop network, which consist of decentralized wireless mobile nodes. MANET uses temporary ad-hoc network topologies, that allowing people and devices to seamlessly connect to network in areas with no pre-existing communication infrastructure e.g. disaster recovery environments. And mobile ad-hoc network is a collection of nodes that are connected through each other with a wireless medium forming rapidly changing topologies. Routing in mobile ad-hoc network is a challenging term due to its dynamic changes in topologies. There are lots of trust models and routing protocol which are used in MANETs to get a security. Various trust schemes are used to provide integrity, confidentiality and availability in mobile ad-hoc network to gain the secure environment. In this paper, we will discuss characteristics, attacks and security in mobile ad-hoc network.
