Mobile ad hoc network is a type of wireless network without a fixed topology consist a set of self-organized nodes which are randomly, frequently and unpredictably mobile. In MANETs packet transmission is affected by radio link fluctuations. Hop count is a simple routing metric that calculate the distance between a source and destination on the number of routers in the path. Routing protocols for ad hoc networks have less channel fading. The minimum hop count is not enough for a routing protocol to achieve a good performance. MANET is an open environment and it is susceptible to many security attacks due to dynamic topology and lack of centralized monitoring authority.
