A Survey on Energy Depletion Attacks in Wireless Sensor Networks
Nalajam Geethanjali, E. Gayathri · 2014
Wireless Sensor Network (WSN), a collection of mobile nodes, is vulnerable to various attacks due to their mobility and resource constrained nature. As this network and its applications became ubiquitous for machine critical applications, it is indispensable to safeguard its communications in energy efficient fashion. Availability of such network is crucial for productivity. Wireless Ad Hoc Sensor Networks are vulnerable Denial of Service (DoS) is the that cause short term unavailability of network. However, the attacks that affect long term availability of the network are resource depletion attacks that cause more damage to the applications for which availability of network is important. This paper presents QoS issues and energy depletion issues and the countermeasures employed. As security QoS, and availability of network are to be given paramount importance, this paper provides insights into the present state of the art pertaining to resource depletion attacks and prevention methods employed.
