Secure & Energy Efficient Scheme against Denial-of-Sleep Attack in WSN

Security breaches and energy consumption issues are indispensable in WSN (wireless sensor networks). Considering attacks like Denial-of-Service (DoS) where not only the service is not provided but in addition to that unwanted power is also consumed.“Denial-of-Sleep attack" (type of DoS attack) also results in unnecessary power exhaustion. This paper briefs about how energy consumption could be minimized in WSN by using MAC algorithm in a risk free manner.
