Weakening the Intruders using PLGP in Wireless Adhoc Sensor Networks

An exhilarating research area in sensing and pervasive computing is ad-hoc low-power wireless networks. Sensor networks pose a number of challenging conceptual and optimization problems such as location, energy consumption, and tracking. Vampire attack is a new class of resource consumption attacks in wireless sensor networks. Denial of communication at the routing or media access control level has been focused in the area of prior security. This proposal discovers resource depletion attacks at the routing protocol layer. The attack permanently stalls the network by quick exhausting battery power of the nodes. These vampire attacks do not rely on specific protocol but suitable on different popular classes of routing protocol. The problem examined is many protocols suspected to vampire attacks, which are stealthy to detect and easy to execute with any compromised user who is sending only protocol compliant messages. Due to the shortcomings in the Ariande, SAOD and SEAD do not protect against the attacks. This lead to the emerge of sensor network routing protocol PLGPa. PLGPa is used to reduce the damage caused by vampire attack. This protocol decreases the energy consumption and depletion of resources.
