CAODV Free Bl ackhole Attack in Ad Hoc Networks
Watchara Saetang, Sakuna Charoenpanyasak · 2012
Ad hoc networks are the network that having no infrastructure or base station. A node communicates directly to the others with its transmission range. The essential requirement in ad hoc network is the security. The well-known attack is the black hole that having a malicious node advertised itself as a shortest path. This will decrease a throughput of network. In this paper, Credit based on Ad hoc On-demand Distance Vector (CAODV) routing protocol is proposed to detect and eliminate the blackhole attack. The NS-2 simulator has been used to analyze both CAODV and AODV when the blackhole attack is injected in the network. By using our proposed protocol, we can achieve the throughput improvement at about 47 percentages. Keyw ords: A d hoc networks, AODV, Blackhole attack and CAODV
