Provided are a simulation apparatus and method used to simulate a sensor network. A sensor node of a real node is reflected in a simulation, and bidirectional communication is performed between a real node and a virtual node, in order to reflect a real environment and a simulation environment in each other and make the real node and the virtual node consistent with each other, thereby performing simulation.

Simulation apparatus and method used for sensor network

A network having a hierarchical structure includes a plurality of clusters. Each of the clusters includes a plurality of nodes and a cluster head connected to the nodes in a mesh format. Each of the nodes is connected to other clusters via the cluster head.

Wireless sensor network having hierarchical structure and routing method thereof

An intrusion detection system and method of a wireless network providing wireless communication to one or more wireless terminal, and an intrusion detection sensor capable of detecting attacks against wireless network are provided. The intrusion detection system of a wireless network includes: an access point providing wireless communication to a wireless terminal; and an intrusion detection sensor examining packets transmitted and received between the access point and a wireless terminal according to a predetermined detection rule. The access point transmits confirmation information on whether or not an event packet, including critical information on whether or not a wireless line connection between the access point and the wireless terminal is established, is transmitted, to the intrusion detection sensor, and the intrusion detection sensor examines an event packet by using the confirmation information. According to the system and method, a variety of attacks occurring on a wireless network can be effectively detected and systematically controlled.
