Sinkhole Attack Detection in WSN using Pure MD5 Algorithm

Objective: To detect the sinkhole attack in AODV routing in wireless sensor network and provides the security. Methods: This employs an energy power consumption mechanism in AODV routing with external energy supplied through the battery. Security is achieved through pure MD5 algorithm detects sinkhole attack and prevents the network from severe attack. This approach provides better performance compared with normal AODV routing. The energy power consumption AODV routing selects the node in the network based on the node which is having more energy to transmit, as a neighbour. This implies that the network continues routing even though any one node in routing possesses less energy to transmit. Findings/Result: Simulation result obtained through Ns2 shows that the detection of sinkhole attack using MD5 security algorithm achieves 93% packet delivery rate, 80% throughput and 500 ms end to end delay in the network.
