Abstract: Wireless sensor networks are widely applied in rang fields to provide responsive information. The secrecy of the data must be maintained over the open communication medium between the wireless sensor nodes. To provide security for the sensor nodes and the network data, the watchdog sensor nodes have been chosen randomly or hierarchically to detect the adversaries. The previous methods deal with static wireless sensor network to detect the intrusions where the sensor nodes are deployed randomly and dont move anywhere. In Wireless Adhoc Sensor Networks (WASNs), the sensor nodes are always in motion through different transmission regions with various levels of velocities. To select the watchdog sensor nodes or guard nodes in this type of sensor network is really, a challenging task for recent researches. At the same time, here, also the adversaries are moving from one location to another location around the network to do their jobs. To provide flexible security in this Wireless Adhoc Sensor Networks (WASNs), here the secure routing and monitoring protocol has been proposed with multi-variant sigryption using Advanced Encryption Standard (AES) and Digital Signature Authentication (DSA) approach to detect and prevent the moving global adversaries. Based on this approach, the sensor guard nodes are selected randomly and invisibly using complex key management approaches. This will give resilient protection to the Wireless Adhoc Sensor Networks (WASNs) against multiple adhoc adversaries.
