    Abstract: A wireless sensor network is a collection of nodes organized 
  in to a cooperative network. Each node consists of processing capability, multiple 
  types of memory, a power source and actuators and sensors. This wireless sensor 
  network is established in hostile and harsh environments like civil and military 
  applications. This network is prone to various attacks. One of them is clone 
  attack. An adversary can capture the node and replicate the node including its 
  cryptographic information and deploy these nodes in the network. This will lead 
  to several problems. This study proposes X-RED which detects clone nodes in 
  the static wireless sensor networks in dynamically fast manner. It is a distributed 
  protocol which computes the witness nodes dynamically. Researchers show that 
  this protocol satisfies the major requirements of the distributed algorithms. 
  Simulation results show that the protocol is more efficient than other exiting 
  protocols in terms of detection probability.
