Due to fundamental characteristics, routing protocols in wireless Mobile Ad hoc NETworks (MANETs) are particularly vulnerable to attack as the medium is easily monitored, the topology of the network is dynamic, the networking protocol rely on distributed cooperation of the nodes, and the nodes have constrained capabilities, lack of a trusted centralized authority and limited resources. So security is an essential requirement in Mobile Ad hoc NETwork (MANETs). There are different kinds of attacks that can be introduced in wireless network. The authors' paper particularly studies sinkhole attack and different parameters of sinkhole detection.
