Lightweight Key Distribution for Secure Routing and Secure Information Propagation

MANET is considered as a type of wireless sensor networking, it can be affected by many types of attack specifically on clusters and has main concern in the loss of information from the MANETs. Our proposed technique is concerned with selective packet drop from the selective forwarding attack. With this packet, throughput of the system get affected and results in the reduction of throughput. MANET associate with the network of mobile nodes. With the help of secure routing and key management schemes we can secure our MANET. For the proposed technique we have studied the existing models related to routing and key management and find out their shortcomings to far better model than the existing ones. In the proposed paper, security schemes for MANET are proposed that include lightweight key exchange scheme having randomized key generation scheme that provide security to data propagation in the MANET clusters. Experimental result shows that proposed technique gives better results as compared to existing technique.
