Improved energy efficient secure multipath AODV routing protocol for MANET

In mobile ad hoc network (MANET), energy consumption is one among the foremost vital restrictions that deteriorate the performance of the whole network. Multi-path routing is better than the single path routing in ad hoc networks, because multi path routing allows the establishment of multiple path between a single source and single destination node. This paper presents a new approach of energy efficient secure multipath AODV (EESM-AODV) routing protocol for MANET based on AODV protocol is modified and converted to work on multiple path. Differing types of routing protocols planned over the years with minimal management overhead and network resources. AODV is well-liked routing protocol among others. It is a loop free, no centralized authority, single path, On-demand routing protocol and its performance is superior than different routing protocols in MANET. However, single path plan is that the most vital drawbacks of AODV. Also, it is a heap of routing overhead at the time of route repair and route discovery method. The mobile nodes in MANET also have restricted resources like battery power, restricted information measure that solely single path protocols cannot handle efficiently. so routing is also a really vital issue inside the look of a MANET. Multipath routing permits the multiple methods between one source and single destination node and during this paper conjointly offer security by filtering route discovery process in AODV routing protocol. The proposed approach contains an adaptive technique in which the our proposed scheme is more energy efficient. The filtering forwarding scheme slows down the spread of excessive RREQs originated by a node per unit time and with success prevents Denial of service attacks. This paper planned multipath extensions of AODV routing protocol and a security improvement against We compared results of AODV routing protocols in attacked condition and after applied our algorithm and enhance the results exploitation multipath scheme for AODV. We used ns-2 to simulate. Simulation results show that the energy consumption of network is less after applying our proposed algorithm and our Network gets more stable and that proposed technique has better packet delivery ratio and improved throughput.
