Overview:

Battery energy is frequently the most limiting resource on mobile devices. Energy-Based Denial-of-Service (e-Dos) attacks, in which malicious attackers initiate actions that can deplete the battery of a mobile node, have recently emerged.

However, little work has been done to evaluate their effectiveness at different layers of a functional wireless network protocol stack or quantify the energy drain. This paper investigates the energy profile of e-DoS packet flood attacks at the MAC, network, transport, application and physical (by moving the mobile node) layers in a real 802.11 wireless testbed.
