Comparative Analysis of Black Hole Attack in Ad Hoc Network Using AODV and OLSR Protocols

Security is an essential factor in wireless ad-hoc network to have safety in transmitting data packets between two wireless sensor nodes. The nodes posses a unique characteristics and it leads to consequential challenges to security design. Comparing to other wireless networks WSN has more security problem; this may be due to its nature of broadcasting messages, resources and their environment. One of the traditional and main attacks of WSNs is Black Hole Attack.
