|Related article at Pubmed, Scholar Google|
The wireless network access is incredible growth in current and next generation mobile communication culture. By default in future generation, the wireless mobile node user’s ratio must be increased. The security and energy consumption crisis in the wireless networks has become important role. The significant essentials of wireless networks are, to extend the efficient energy utilization, security of the network and network lifetime. In the heterogeneous wireless networks, the energy efficiency of wireless systems has to be significantly improved by green wireless communications. All communication technologies using several security methods for protecting network resources as well as data part also. Such types of schemes are having some issues .This paper, concentrated on security aspects of the heterogeneous wireless networks such as harmful network DDos attacks and secure solutions for those attacks. This survey paper mainly focused DDos attack that is mainly disturb the network life time, energy efficiency, delay. Many security schemes and distributed defense systems are availed. Such kind of attacks and secure solutions are over viewed here.
