BAMBi: Blackhole Attacks Mitigation With Multiple Base Stations in Wireless Sensor Networks

Black hole attacks occur when an adversary captures and re-programs a set of nodes in the network to block/drop the packets they receive/generate instead of forwarding them towards the base station. As a result any information that enters the black hole region is captured. Black hole attacks are easy to constitute, and they are capable of undermining network effectiveness by partitioning the network, such that important event information do not reach the base stations. Several techniques based on secret sharing and multi-path routing have been proposed in the literature to overcome black hole attacks in the network.
