Effect of pause time on AODV and TSDRP routing protocols under black hole attack and DoS attacks in MANETs

Mobile Ad Hoc Networks (MANETs) are collections of mobile nodes that can communicate with one another using multihop wireless links and often deployed in the environments, where there is no fixed infrastructure and centralized management. The nodes of mobile ad hoc networks are susceptible to compromise. In such a scenario, designing a trustworthy and secure routing protocol has been a major challenge over the last many years. This paper study the impact of pause time of our propose Trust Based Secure On Demand Routing Protocol called “TSDRP” and Ad hoc On-demand Distance Vector (AODV) routing protocol for making it secure to thwart attacks like Blackhole attack and DoS attack. To evaluate the performances, we have considered Packet Delivery Fraction (PDF), Average End-to- EndDelay (AED), Average Throughput (AT) and Normalized Routing Load (NRL).
