A Novel Method Defends against the Path Based DoS for Wireless Sensor Network

WSNs are significantly different fromthe traditional network architecture due to its wireless communication, energy limitation, and computation constraint and environment of the application. Because of these differences, security becomes a critical issue. The path based denial of service (PDoS) attacks harmthe networkmaintenance and cause serious damage in the resource constrained WSNs. In a PDoS attack, an adversary can overwhelm sensor node and cluster head node to flood packets along the rout
