TBSMR: A Trust-Based Secure Multipath Routing Protocol for Enhancing the QoS of the Mobile Ad Hoc Network

Algorithm 2

Malicious node detection.

  Malicious_node_detection ( )

  {

  for each neighbor node n

  do

  if (nrecv > nfowd) || (nfowd = = 0)

  {

  mark node n as malicious. propagate this information to other nodes

  }

  else if (nrecv = = nfowd)

  {

  If (size_of_pkt! = 512 bytes)//change in packet size

  {

  Mark node n as malicious node

  Propagate this information to other nodes

  }

  }

  else

  forward packets to node n
