摘要：Compromised node and denial of service are two key attacks in wireless sensor networks. Data delivery mechanisms that can with high probability circumvent black holes formed by thee attacks. We argue that classic multipath routing approaches are vulnerable to such attacks, mainly due to their deterministic nature. So once the adversary acquires the routing algorithm it can compute the same routes know to the source, hence, making all information sent over these routes vulnerable to its attacks. We developed mechanisms that generate randomized multipath routes. Under our design, the routes taken by the “ shares” of different packets change over time. So even if the routing algorithm because known to the adversary, the adversary still cannot pinpoint the routes traversed by each packet. Besides randomness, the generated routes are also highly dispersive and energy efficient, making them quite capable of circumventing black holes. We analytically investigate the security and energy performance of the proposed scheme.
