Dynamic Position Location and Tracking (D-PL&T) using Location based Hash Scheme for Malicious Detection under Doppler Spread Rayleigh Channel

A novel approach of the integrated security and dynamic Position Location and Tracking (PL&T) for malicious node maintaining two friendly nodes is proposed. Location based hash security scheme is deployed for detection of friendly and malicious nodes by encrypting hash functions using private location assets to increase the security level. In addition, PL&T is deployed forming the robust tracking zone and triangulation using two friendly nodes equipped with steered Directional antenna in Mobile Ad hoc Networks. The integrated “zone finding” and “triangulation” with adaptive beam forming allow the system to use only two references by switching nodes in and out of range. Pre-zone finding of a node permits proper geometry to be established for triangulation. This provides significantly improved tracking accuracy as compared to the triangulation only using three references. Also, narrow zone reduces beam width, thus significantly decreasing the tracking error but increases the zonal overhead. The PL&T performance analysis shows that by deploying interleaving Koay-Vaman (KV) transform coding technique for forward error correction and sample interleaving will achieves greater tracking accuracy using lower Eb/No in fast Doppler spread Rayleigh channel. The average estimated location tacking errorand average zonal overhead are significantly decreased under fast Doppler spread fading channel than slow Doppler spread fading channel.
