Abstract: MANET (A Mobile Ad-hoc Network) is a network where nodes are not connected that is it is a wireless network where nodes are configured dynamically. Wireless network means there will be issues with network security that is an intruder get into the network and does flooding attack, black hole attack and a gray hole attack. To provide network security a better approach called TS-AOMDV-Trust-based Secured Ad-hoc On-demand Multipath Distance Vector is used than Ad hoc On-Demand Multipath Distance Vector (AOMDV) Routing protocol. TS-AOMDV uses Intrusion detection system and a trust-based routing factor so this provides a better security and a routing performance.

Keywords: Mobile Ad-hoc Network, TS-AOMDV, AOMDV, Intrusion detection system.
