Trustworthy Position Based Routing to Mitigate against the Malicious Attacks to Signifies Secured Data Packet using Geographic Routing Protocol in MANET
Authors: ,
Abstract: A mobile ad hoc network (MANET) is a dynamic wireless network that can be formed without any preexisting infrastructure in which each node can act as a router. Instead of using topology based routing protocolto prefer Geographic Routing Protocol (GRP) become scalability and to improve more successive rate and also reducing the overhead. Here proposed a novel secure position-based routing protocol, it takes dynamic pseudo identifiers instead of its real identity in advertising its position. Though the MANET hasdifferent malicious attacks such as flooding, black hole and wormhole etc., because of simulation studies demonstrate that the networks with 15% malicious nodes show significant performance degradation. In order to present secure communication and transmitting recommended that this tactics is actually asymmetric encryption technique. Simulation is focused to take measurements were taken in the light of throughput, end-to-end delay and network load and using the modified asymmetric cryptographic system to improve the through put and reduced the packet drop against malicious attacks. Simulation is done in Optimized Network Engineering Tool (OPNET).
