  Security Vulnerabilities in Channel Assignment of Multi-Radio Multi-Channel Wireless Mesh Networks
Anjum Naveed, Salil S. Kanhere, University of New South Wales 		View Abstract... In order to fully exploit the aggregate bandwidth available in the radio spectrum, future Wireless Mesh Networks (WMN) are expected to take advantage of multiple orthogonal channels, with nodes having the ability to communicate with multiple neighbours simultaneously using multiple radios (NICs) over orthogonal channels. Dynamic channel assignment is critical for ensuring effective utilization of the non-overlapping channels. Several algorithms have been proposed in recent years, which aim at achieving this. However, all these schemes inherently assume that the mesh nodes are well-behaved without any malicious intentions. In this paper, we expose the vulnerabilities in channel assignment algorithms and unveil three new security attacks: Network Endo-Parasite Attack (NEPA), Channel Ecto-Parasite Attack (CEPA) and low-cost ripple effect attack (LORA). These attacks can be launched with relative ease by a malicious node and can cause significant degradation in the network performance. We also evaluate the effectiveness of these attacks through simulation based experiments and briefly discuss possible solutions to counter these new threats. View Full Program...
  Defending Multi-hop Ad Hoc Networks Against Distributed Flooding Attacks That Use Address Spoofing
Yinghua Guo, Steven Gordon, University of South Australia 		View Abstract... The broadcasting mechanism used by various routing protocols in Mobile Ad hoc Networks can be exploited by a malicious node to launch flooding, or Denial of Service, attacks. In order to evade being identified by statistics based detection schemes, attackers usually recruit multiple accomplice to dilute attacking traffic density from each attacking source. In addition, they also use the address spoofing technique to challenge attack tracing. In this paper, we investigate the complex flooding attack: multiple-source, distributed, and address spoofing. Further, we propose a detection feature --- the percentage of RREQ addresses that are “new” to a node received in the sampling period, RREQNew --- that behaves differently in normal network senarios and attacking scenario. Applying cumulative sum algorithm on the detection feature, we can effectively identifying this type of attack by observing a significant increase on RREQNew. View Full Program...
  Channel MAC : A Novel Medium Access Control Paradigm for Wireless Ad Hoc Networks
Manzur Ashraf, Aruna Jayasuriya, Sylvie Perreau, Lars Rasmussen
University of South Australia 		View Abstract... The IEEE 802.11 has been the dominant MAC protocols used in wireless ad hoc networks. It has been shown theoretically that significant performance improvements as compared to 802.11 can be achieved in random access wireless networks. In this paper we propose a new paradigm of medium access control, based on principles of opportunistic transmission, to improve the performance of wireless ad hoc networks. Simulation results obtained shows a significant improvement of throughput compared to 802.11 MAC layer. View Full Program...

  Minimum Latency Broadcasting in Multi-rate Wireless Mesh Networks
Junaid Qadir, Chun Tung Chou, Archan Misra, University of New South Wales		 View Abstract... In a multi-rate wireless network, a node can dynamically adjust its link transmission rate by switching between different modulation schemes. For the current IEEE802.11a/b/g standards, this rate adjustment is limited to unicast traffic. In this paper, we describe the solutions to the problem of efficient routing and packet distribution for multicast traffic flows in a multi-rate wireless mesh networks (WMN).We assume that the media access control (MAC) layer of future WMNs will provide some form of multicast support, where the transmitter may be able to specify the transmission rate of the MAC-layer multicast, and, either explicitly or implicitly, the recipients of the multicast. Assuming such MAC layer multi-rate multicast capability, our goal is to study how low-latency (and possibly high throughput) network layer multicast of data traffic can be realized.
