A Review of Wireless Sensor Network Under the Denial Of Service Attack (DoS)

Wireless Sensor Networks are used widely in numerous fields for countless applications such as pollution check, soil erosion, military applications etc. WSN include sensing + processing + storage + transmission. It has sensor nodes connected wirelessly deployed over an area or a person according to the requirement. It collects the information and sends it to the base station and server for analysis using radio frequency transmission at the real time. DoS attacks are such attacks which prevent the legitimate user from accessing the network or resources. Such attacks include blackhole attack, sinkhole attack, ddos attack etc. Attack can be possible on the sensory nodes, routing path of the data .These attacks could change the data collected or even prevent the data from reaching the destination. This could lead to the incomplete or falsified data at the server which further results in a wrong interpretation of the crucial information regarding the specific area, person or environmental conditions etc. This is a review paper about WSN under the effect of DoS attacks. This paper shall provide a review of the various methods and strategies developed so far to mitigate or completely eliminate the DoS attacks detected in a WSN.
