This paper describes an INtrusion-tolerant routing protocol for wireless SEnsor NetworkS (INSENS).INSENS constructs forwarding tables at each node to facilitate communication between sensor nodes and a base station.It minimizes computation, communication, storage, and bandwidth requirements at the sensor nodes at the expense of increased computation, communication, storage, and bandwidth requirements at the base station.INSENS does not rely on detecting intrusions, but rather tolerates intrusions by bypassing the malicious nodes.An important property of INSENS is that while a malicious node may be able to compromise a small number of nodes in its vicinity, it cannot cause widespread damage in the network.A prototype implementation in the ns2click simulator is presented to demonstrate and assess INSENS's tolerance to malicious attacks launched by intruder nodes in random and grid topologies.
