Worm hole-black hole attack detection and avoidance in Manet with random PTT using FPGA
K. Arun Kumar · 2016
Manet or Mobile Ad-Hoc Networks are self-forming networks which does not require a fixed infrastructure for its communication. Manet plays a critical role in Military Communication and Disaster Management system. Initially there will be multiple nodes with separate address assigned from an address pool, which will form the network when needed. Worm-hole attack and black-hole attack are the severe security issues faced by Manet. The normal security mechanisms like encryption and authentications have no big roles in these types of attacks. The paper discuss the FPGA implementation of black hole-worm hole detection and avoidance algorithm. The packets from a black-hole or worm-hole are detected in the MAC-Physical layer itself by randomly varying the Packet Travel Time (PTT). The Mac layer and the physical layer are implemented using Partial-Reconfiguration technique so that the symbol rate, modulation schemes and coding rate can be changed randomly while the system is running without using extra hardware. Probe request and probe response messages are used to ensure authentication for the nodes for forming the network.
