An Empirical Approach for the Detection of Malicious Node in Cluster Based Adhoc Wireless Networks?

A Mobile Ad Hoc Network (MANET) is a collection of mobile nodes who communicates with each other via wireless links either directly or through some other nodes such as routers. Due to the dynamic change in topology finding a proper route is very difficult. Some nodes misbehave as they participate in route establishment phase but refuse to forward the data packets to drop their own energy. The misbehaving node moves from one place to another dropping the packets. A mobile Ad hoc network (MANETs) is a multi-hop wireless network in which message is transmitted from source to destination. These networks can be setup easily anytime and anywhere without any base infrastructure, as they are infrastructure less thus they have proved to be very efficient is rescue related areas like flood and fire. MANETs are now extended to be used in military and law enforcement. Still there are some problems in MANET about security and privacy, especially when used in sensitive areas of computing. Secure routing protocols have been developed to provide various levels of security and privacy in the past.
