Black hole and grey hole attack is most happening attacks in mesh networks. Mesh networks means non-static networks with making loops of networks with the help of active hotspots. In wireless networks all the communication between the nodes is happening wirelessly and the nodes are so much resource constraint that it is difficult to employ any security solutions of other ad hoc networks. So they are attacked by malicious nodes. In black hole attack the attacker windup all the information and dropped it. In black hole attack, the series of RREQ (Route REQuest) and RREP (Route REPly) follows the smallest way of networking communication.
