Elimination of energy and communication tradeoff to resist wormhole attack in MANET

Challenges in meeting the best security standards is still an unsolved question in the area of mobile adhoc network especially pertaining to wormhole attack. Although there are many existing solutions, but majority of them suffers from various trade-off. This paper discusses about the significant issues of the existing techniques and presents a novel secure routing protocol that was found to have sufficient supportability of complex cryptographic algorithms as security measure along with enhancement of data transmission performances. The proposed routing strategy is designed by enhancing the multicast routing protocols by adding few simple entities e.g. Additional Supportive Beacons (ASR), Route-Discovery Beacons (RDB), and Auxiliary Nodes (AN). The outcome of the study shows that proposed technique excels better than existing multicast routing protocol in energy efficiency and packet delivery ratio.
