IDS in Wired and Wireless Networks with port database
Abstract
This project is a network layer intrusion detection system with port identification by
detection systems (sensors) for detecting a false intruder by comparing the existing port
numbers in the database with the intruder port number. The intrusion detection system is
for both homogeneous and heterogeneous wireless networks as well as for a wired
network scenario.
Intrusion detection in Wireless Sensor Network (WSN) is of practical interest in
many applications such as detecting an intruder in a battlefield. The intrusion detection is
defined as a mechanism for a WSN to detect the existence of inappropriate, incorrect, or
anomalous moving attackers. In this project, we consider this issue according to
heterogeneous WSN models. Furthermore, we consider two sensing detection models:
single-sensing detection and multiple-sensing detection... Our simulation results show the
advantage of multiple sensor heterogeneous WSNs.
We analyze the intrusion detection problem under two application scenarios: single-
sensing detection and multiple-sensing detection. According to the capability of sensors, we
consider two network types: homogeneous and heterogeneous WSNs We define the sensor
capability in terms of the sensing range and the transmission range. In a heterogeneous
WSN some sensors have a larger sensing range and more power to achieve a longer
transmission range. Furthermore, in a heterogeneous WSN, high capability sensors usually
undertake more important tasks (i.e., broadcasting power management information or
synchronization information to all the sensors in the network,it is also desirable to define
and examine the broadcast reachability from high-capability sensors. The network
connectivity and broadcast reachability are important conditions to ensure the detection
probability in WSNs. They are formally defined and analyzed in this project.
