Cellular Neural Network-Based Methods for Distributed Network Intrusion Detection

Table 2

The comparison of current DIDS policy.

Title	Type	Characteristics	Limitations
DIDS	Centralized architecture DIDS	Artificial intelligence techniques [7]	(1) Data communications may occupy considerable network bandwidth.; (2) The privacy of the data cannot be protected and is very sensitive to Denial of service attack.
		Multilayered framework [8]
		Self-organized model [9]
	Distributed architecture DIDS	ANN [12]	There is a large number of communications between local nodes.
		Signature-based multilayer IDS [13]
		Dynamic Election Algorithm [14]
