Scalability and Robustness of a Network Resource Allocation System Using Market-Based Agents
No full textIn this paper, we consider issues associated with scalability and robustness in designing a market-based multi-agent system that allocates bandwidth in a communications network. Specifically, an empirical evaluation is carried out to assess the system performance under a variety of design configurations in order to provide an insight into network deployment issues. This extends our previous work in which we developed an application that makes use of market-based software agents that compete in decentralised marketplaces to buy and sell bandwidth resources in a network that is partitioned into regions, each with a separate market server. We investigate the average call success rate and average message load per market server, as the number of markets are scaled up in a fixed size network. The same investigations are performed in the presence of single market failures. Finally, for both the failure and non-failure cases, a trade-off is found between their average call success rates and message load per server in order to find an optimum number of regions to deploy in the network
Scalability and robustness of a market-based network resource allocation system
No full textIn this paper, we consider issues related to scalability and robustness in designing a market-based multi-agent system that allocates bandwidth in a communications network. Specifically, an empirical evaluation is carried out to assess the system performance under a variety of design configurations in order to provide an insight into network deployment issues. This extends our previous work in which we developed an application that makes use of market-based software agents that compete in decentralised marketplaces to buy and sell bandwidth resources. Our new results show that given a light to moderate network traffic load, partitioning the network into a few regions, each with a separate market server, gives a higher call success rate than by using a single market. Moreover, a trade-off in the number of regions was also noted between the average call success rate and the number of messages received per market server. Finally, given the possibility of market failures, we observe that the average call success rates increase with an increasing number of markets until a maximum is reached
The Use and Abuse of Power and Why We Need a Bill of Rights: The AS10 (Terrorism) Amendment Act 2003 (Cth) and the case of R v UI-Haque
No full textThis paper assesses the legislative changes contained in the Australian Security Intelligence Organisation Legislation Amendment (Terrorism) Act 2003 (Cth) and their effects, in light of the recent case of R v Ul-Haque. The author argues that this case is significant for a number of reasons: first, it illustrates the extent to which the new powers are open to abuse by ASIO officers. Second, it argues that those powers erode the fundamental legal principles of a democratic state, including the right to silence, the right to adequate legal representation and most importantly, the right of habeas corpus. Third, on the basis of a comparison between the interviews conducted by ASJO and those conducted by the Australian Federal Police, the case demonstrates why it is inappropriate for ASIO to wield detention and interrogation powers. Finally, the author suggests that the case highlights the growing need for a statutory bill of rights on at least two grounds: to ensure that rights are protected at law and to promote civics education

Counter-terrorism interviewing and investigative interoperability: R v ul-Haque [2007] NSWSC 1251
No full textIn R v ul-Haque [2007] NSWSC 1251, Justice Adams excluded Izhar ul-Haque's admissions of training with a terrorist organisation made to Australian Federal Police (AFP) officers during interviews on 7 and 12 November 2003 and 9 January 2004. Those interviews followed earlier questioning of ul-Haque by Australian Security and Intelligence Organisation (ASIO) officers on 6 and 7 November 2003. As a result of the inadmissibility finding, charges were dropped against ul-Haque. The prior ASIO questioning was held to be both unlawful and improper via ss 84, 85 and 138 of the Evidence Act 1995 (NSW) which lead to the inadmissibility of ul-Haque's admissions obtained at the subsequent AFP interviews. This case illustrates the possible tensions between intelligence-gathering by ASIO officers and prosecution-focused, evidencegathering by the AFP in the investigation of the same alleged terrorist activity. Justice Adams' criticisms are analysed in terms of recommendations from The Street Review, The Carnell Report, ASIO's detention and questioning powers, and empirical psychological research on questioning practice
Effects of neglecting carrier tunneling on electrostatic potential in calculating direct tunneling gate current in deep submicron MOSFETs
No full textWe investigate the validity of the assumption of neglecting carrier tunneling effects on self-consistent electrostatic potential in calculating direct tunneling gate current in deep submicron MOSFETs. Comparison between simulated and experimental results shows that for accurate modeling of direct tunneling current, tunneling effects on potential profile need to be considered. The relative error in gate current due to neglecting carrier tunneling is higher at higher gate voltages and increases with decreasing oxide thickness. We also study the direct tunneling gate current in MOSFETs with high- gate dielectrics
Resource allocation in communication networks using market-based agents
No full textThis work describes a system that allocates end-to-end bandwidth, in a switched meshed communications network. The solution makes use of market-based software agents that compete in a number of decentralised marketplaces to buy and sell bandwidth resources. Agents perform a distributed depth first search with decentralised markets in order to allocate routes for calls. The approach relies on a resource reservation and commit mechanism in the network. Initial results show that under a light network load, the system sets up a high percentage of calls which is comparable to the optimum value and that, under all network loads, it performs significantly better than a random strategy
