Mobile ad hoc networks (MANETs), also known as wireless ad hoc networks, are an emerging technology that neither it depends on fixed infrastructure nor requires a centralized administration mechanism. It is frequently composed of mobile devices, which can arrange themselves in various ways and operate without strict rules of network administration. Each node in a MANET can act as both as a router and as a host. MANETs face many performance issues so it needs to be enhanced to improve their performance such as adding a trust mechanism. In this paper, we compared the performance of the default AODV with AODV under blackhole attack. Also, we compared the performance of TRAODV under blackhole attack with AODV under black hole attack. We compared them under the effect of different mobility speed to see how the nodes mobility speed and blackhole attack will affect their performance by using the simulation tool NS-2.35. TRAODV is an enhanced version of AODV with a direct trust algorithm that improved the protocol route preference. Both the PDR and throughout in all the protocols start decrease as the node mobility speed increases. The overall evaluation shows that TRAODV performs better than AODV when they are under blackhole attack.
