Deep Analysis of Intrusion Detection System for Mobile Devices with Networking System

An Intrusion Detection System (IDS) is a system that monitors network traffic for suspicious activity and issues alerts when such activity is discovered. It is a software application that scans a network or a system for harmful activity or policy breaching. MANETs have various defining characteristics that differentiate them from other wired and wireless networks. MANETs are formed based on the collaboration between independent, peer-to-peer nodes that wish to communicate with each other for a particular purpose. No prior organization or base station is defined and all devices have the same role in the network. In addition, there are no pre-set roles such as routers or gateways for the nodes participating in the network unless specific arrangements are provided. Wireless links that connect the MANET nodes have much smaller bandwidth than those with wires, while the effects of interference, noise and congestion are more visible, causing the available bandwidth to vary with the surrounding conditions and to be even more reduced. MANET depends on radio frequency (RF) or infrared (IR) technology for connectivity, both of which are generally short range. Therefore, the nodes that wish to communicate directly need to be in close proximity to each other. To overcome this limitation, multi-hop routing techniques are used through intermediate nodes that act as routers to connect distant nodes.
