Survey of different countermeasure on network layer attack in wireless network

Abstract

In recent times, wireless network builds a bridge between the physical and virtual worlds. It poses security threats at different layers. The most vital security issue is observed on the network layer on different wireless networked systems. Defense mechanisms are used to shield the network layer from these repetitive malicious attacks. Malicious hubs are detected and differentiated along the network by using these mechanisms. These networks truly require a unified security answer for ensuring both course and information transmission tasks on the network layer. Without a suitable security solution, malicious nodes in the network can disturb rapidly across the network. This just irritates the system activity from exact delivery of packets and malevolent hubs that can disturb transmissions or drop all packets going through them. The main objective is to outline the different attacks and the countermeasures used to ensure the network security against pernicious attacks.
