In MANETs (Mobile Ad hoc NETworks), security is common problem and lack of issues in MANET network. When comparing to wired network, MANETs are harmed to security attacks due to the scarcity of a trusted centralized enforce authority and limited resources. This paper proposed a technique to avoid blackhole node behavior in AODV (Ad hoc On-demand Distance Vector) using hexagonal encryption in NS2. Hexagonal encryption has been chosen for low cost and high computation speed up. Compared to existing blackhole detection technique, this proposed technique obtains better result by stimulating in NS2.
