A Vampire attack is the composition and transmission of a message that sources more power to be consumed by the network than if an open node transmitted a message of the same size to the same destination although using different packet headers. The authors calculate the potency of the attack by the ratio of network energy used in the benevolent case to the energy used in the malicious case i.e. the relation of network-wide power operation with malicious nodes present to energy procedure with only honest nodes when the number and size of packets sent remains stable.
