Wireless Sensor Networks (WSNs) are currently used in many application areas such as military applications, control and tracking applications, habitat monitoring applications where they face attacks already experienced by the Internet and wireless ad-hoc networks. One such attack is that of black-hole Denial-of-Service (DoS). In black-hole attack a node captures all data packets coming to it. WSNs have Sensor Nodes which have limited energy and processing capability. With the resource limitations of WSN devices, they are particularly susceptible to the consumption and destruction of these scarce resources.
