Survey on network access control technology in MANETs.

Using Mobile Ad hoc Networks (MANETs) is growing with advances in technology. MANETs consist of few nodes with constrict resources and without any special structure. Each node can be connected to other nodes in its own transition rate. Network access control with respect to the development of networks is very important. In this paper, we explain the Network Access Control (NAC), the mechanism of action in the networks and also compare some NAC vendors. We briefly describe four network access control protocols for MANET and also compare them in terms of efficiency, communication complexity, overhead, and the techniques which is used. In the other part we describe the attacks in MANETs. [ABSTRACT FROM PUBLISHER]
