Routing

Wormhole Attack Tunnel packets
received in one place of the network and replay them in another place
The attacker can have no key material. All it requires is two transceivers and one high quality out-of-band channel Adapted from Chris Karlof and
David Wagner's WSNPA slidesWormhole Attack
12
Disrupted Routing
Most packets will be routed to the wormhole
The wormhole can drop packets or more subtly, selectively forward packets to avoid detection

BANAID BANAID is
composed of: 7 Mica2 sensors. 2 Stargates.
The topology is assumed to be fixed.
Each sensor knows its neighbors.
BANAID
15
BANAID Three programs have
been written and installed: TOSBase program
(sensor 5, and 6). Stargate program
(stargate 1, and 2). Simple customized
AODV program (sensor 1,2,3 and 4).

BANAID
Timing mechanism is required to detect Wormhole attack[1].
The average transmission delay in each sensor is ≈45 msec (Td ≈ 45msec) [2].

BANAID Delay on the real
path: Ns * Td. 3 * Td.
Delay on the fake path:
Ns * Td. 2 * Td

Conclusion Wormhole attack is a significant danger
to routing protocols WSN. BANAID implemented one of the
Wormhole attack’s solutions for WSN which is Packet Leaches [1].
The destination is able to detect the fake packet if the difference in time stamp is < (Ns * Td) where Ns is the number of sensors/hops between source and destination in the real path.
QUIZ What is the function of TOSBase?
1. Initiates Wi-Fi connection
2. Exchange packets with other Mica2
3. Forwards packets received from radio antenna to serial port and vice versa.
4. Exchange routing information.
