Implementation and Evaluation of A Low-Cost Intrusion Detection System For Community Wireless Mesh Networks

Rural Community Wireless Mesh Networks (WMN) can be great assets to rural communities, helping them connect to the rest of their region and beyond. However, they can be a liability in terms of security. Due to the ad-hoc nature of a WMN, and the wide variety of applications and systems that can be found in such a heterogeneous environment there are multiple points of intrusion for an attacker. An unsecured WMN can lead to privacy and legal problems for the users of the network. Due to the resource constrained environment, traditional Intrusion Detection Systems (IDS) have not been as successful in defending these wireless network environments, as they were in wired network deployments. This thesis proposes that an IDS made up of low cost, low power devices can be an acceptable base for a Wireless Mesh Network Intrusion Detection System. Because of the device's low power, cost and ease of use, such a device could be easily deployed and maintained in a rural setting such as a Community WMN. The proposed system was compared to a standard IDS solution that would not cover the entire network, but had much more computing power but also a higher capital cost as well as maintenance costs. By comparing the low cost low power IDS to a standard deployment of an open source IDS, based on network coverage and deployment costs, a determination can be made that a low power solution can be feasible in a rural deployment of a WMN

Efficient Routing in Suburban Ad-Hoc Networks (SAHN) Abstract Muhammad Mahmudul Islam Ronald

A suburban ad-hoc network (SAHN) is an economical, high-speed alternative for communities of cooperating users. The SAHN aims to provide broadband suburban area connectivity for local area networks with low costs using wireless technology. There exists a plethora of efficient routing solutions for ad-hoc networks. However, less attention has been paid towards optimizing these protocols for ad-hoc networks with a quasi-static topology 1. In this paper we outline an efficient routing algorithm, particulary for a suburban ad-hoc network, to make efficient use of network resources. Our primary comparison results are with respect to DSR and AODV

A Router Architecture to Achieve Link Rate Throughput in Suburban Ad-Hoc Networks. A Omondi and

Abstract. Static nodes, e.g. houses, educational institutions etc, can comprise ad-hoc networks using off-the-self wireless technologies with a view to bypass expensive telecommunication solutions. A suburban adhoc network (SAHN) aims to provide such an inexpensive broadband networking alternative for communities of cooperating users using wireless medium. There exists a plethora of efficient routing solutions for ad-hoc networks where nodes are mobile. However, less attention has been paid towards optimizing these protocols and developing a real routing system for ad-hoc networks where nodes are not mobile. In this paper we have made analyses of various router architectures and outlined a design framework to perform routing tasks in the SAHN efficiently. We have also presented a survey result for choosing a feasible realtime operating system for our development and deployment purposes.
