MASAP: Mobile Agent Spam Attack Prevention for WSN Environment

Wireless sensor network (WSN) is prone to various security threats; one among them is anti sensor motes with existence of anti mobile agent in it, apart from jamming in WSN traffic it is also one kind of DoS (Denial of service Attack). They inject anti mobile agent to other motes to act as anti sensor motes thus spreading anti mobile agents clone among all neighboring motes and these clones send burst of sensed data to base station for exhausting the power of WSN. This process may continue till the entire WSN become dead. This paper focuses on miss use of power, memory and time consumption from mobile agents that leads to DoS spam mobile agent attack when they became anti mobile agents. We propose a novel Mobile Agent Spam Attack Prevention (MASAP) model to control this kind of DoS attack. Our simulation results validate this MASAP model which is able to stop spreading of anti mobile agent with very little energy, memory and time consumption and hence appropriate for WSN.
