The development of wireless sensor devices in terms of low power and inexpensive data-relaying has been partially achieved because of the rapid progress in integrated circuits and radio transceiver designs and device technology. Due to these achievements, the wireless sensor devices are able to gather information, process them if required, and send them to the next sensor device. In some applications, these wireless sensor devices must be secured, especially when the captured information is valuable, sensitive or for military usage. Wormhole attacks are a significant type of security attacks which can damage the wireless sensor networks if they go undetected. Unfortunately, these attacks are still possible, even if the communication is secured. The wormhole attack records packets at one point of the network, passes them into another node and this last node injects the packet into the wireless sensor network again. This type of attacks can not be avoided by using cryptographic techniques because attackers neither generate new nor alter existing packets. They only forward legitimate packets from part of the network to another part. This attack can cause damage to the route discovery mechanism used in many routing schemes. In this paper we build an actual test bed, which is called BANAID, to simulate the wormhole attack on a wireless sensor network and then implement one of the current solutions against this attack. BANAID consists of a combination of Mica2 motes and Stargate sensor devices
