Query: Hierarchical Partition-Based Anonymous Routing Protocol(HPAR) in Manet
  for Efficient and Secure Transmission   Anonymous routing protocols are used in MANET's to hide the nodes from
outsiders in order to protect from various attacks. HPAR partitions the network
area dynamically into zones and chooses nodes in zones randomly as intermediate
relay nodes .This relay nodes help in secure routing. In HPAR anonymity
protection is given to source, destination and route. HPAR have low cost and
provide high level of protection. It has techniques to counter various attacks.
