Abstract: Mobile Ad-hoc Network (MANET) is a kind of wireless network, which has no infrastructure and is a self configuring wireless network of mobile nodes, each node on the MANET acts like a router which forwards the packets. Due to these properties, MANET is vulnerable to attacks, routing attack is the most common one. The black hole attack is a kind of routing attack made by a malicious node on MANET. This article proposes AODVSC improved from AODV protocol which uses SC (Safe Cycle) solution to detect black hole attacks. The SC solution uses the “distance” from the current node to all neighboring nodes based on SN (sequence number) values. The simulated installation and performance evaluation of AODVSC and AODV protocols in the normal network environment where there are black hole node attacks on the network simulator NS2 was also presented to evaluation improved protocol.
