Optimized & Secure Ad-hoc on Demand Distance Vector Routing Protocol

A Mobile Ad-Hoc Network (MANET) is a collection of wireless mobile nodes in which different routing protocols are used to form the communication network. So, far there are numerous routing protocols are discovered in which AODV performs superior than all. Ad-hoc network suffer from the bunch of issues in which congestion and security are the major issues of concern which leads to severe degradation of network throughput and Packet Delivery Ratio. It also increases the routing overheads and end to end delay. This paper presents a novel design Optimized and Secure AODV which is the modified version Optimized AODV by including new Packet Route Checker. The Route Checker Packet is the additional mechanism in the Optimized AODV to create obstacle against Black-hole attack. The result shows that OSAODV performs better in terms of Packet Delivery Ratio and Throughput than AODV. The simulation has done through network simulator NS-2.
