PERFORMANCE OPTIMIZATION OF WIRELESS ADHOC NETWORKS WITH AUTHENTICATION

Abstract

Adhoc networks as the name suggests is framed for a specialized reason using the volunteering devices available near the source to destination, utilizing the devices in between the source and the destination as the relaying nodes. Several methods were framed to optimize the performance of the wireless adhoc network to retain the energy level of the devices in turn to extend the lifetime of the devices. The cluster based routing seemed to be very promising in terms of energy efficiency, throughput and delay. These cluster based adhoc networks are very much exposed to security breaches as they are not aided with sufficient security. The conveyance taking place between the head of the cluster to base station is often affected by the many attacks from different sources by altering the information or hacking the information. So the paper puts forward the verification code for every data transmitted from the head of the cluster to the base station. The proposed method is validated using the network simulator-2 in the terms of throughput, energy consumption and security in data conveyance and compared with the prevailing methods that bare authentication.
