Security is an essential requirement in mobile ad-hoc networks to provide protected communication between mobile nodes.Due to unique characteristics of MANETs, it creates a number of consequential challenges to its security design.To overcome the challenges, there is a need to build a multifaceted security solution that achieves both broad protection and desirable network performance. MANETs are vulnerable to various attacks, black hole, is one of the possible attacks. Black hole is a type of routing attack where a malicious node advertise itself as having the shortest path to all nodes in...

The need of wireless network is to enforce participating nodes to forward packets to other nodes to foster secure and reliable communication. Although there are presence of vulnerable nodes that can be associated with malicious nodes and can harm networks. The varieties of these malicious nodes are vulnerable to nodes which are either compromised or falsely guided by vulnerable nodes.Malicious nodes can easily tamper the participating nodes in the networks. In mobile ad hoc network these attacks shown their significance in the terms of network worms which can attack, alter or modify the...
