Energy consumption of the internet is high, and increases as the internet expands. It is estimated that the global CO2 emissions due to ICT equipment is 2% worldwide and is expected to double to 4% by 2020 due to the massive growth of internet enabled technology. Hence energy savings in the ICT sector has been gaining considerable attention. Although energy consumption has been rising, the data networks...
A Multiple Access Protocol is an access mechanism and a set of rules for successful transmission of information using a common medium. In this paper, the multiple access protocols studied are those used in communication systems in which the resource to be shared is the communication channel. For wireless communication efficient resource utilization relies upon effective sharing of the available medium...
The number of Point Of Interconnects (PoI) is a critical factor in the proposed Australian National Broadband Network (NBN) because there is a relationship to the Capital and Operational Expenditure. Initially a centralized model with 14 P0Is in 7 major cities was proposed and after a critical evaluation of the mode the Australian Competition and Consumer Commission proposed a decentralized option...
Mobile Ad hoc Networks (MANET) use a communication technique that can transmit data between nodes without the support of fixed infrastructure. MANET is a multi-hop, self configuring and autonomous network that can use intermediate mobile nodes as a router and transmit data between mobile devices. A quadrant based intelligent energy controlled multicast algorithm for MANET identified during earlier...
The 4th generation (4G) mobile access network and the core network are evolving towards a secure, fast, and Internet Protocol-based network. With the emergence of next generation battery-powered smart mobile phone and open source application platforms, security and the terminal's energy consumption have become big issues. Long Term Evolution (LTE) is one of the most popular 4G technologies defined...
As defined in the 3rd Generation Partnership Project specifications, a Universal Mobile Telecommunications System (UMTS) user device has to carry out two authentication steps to access multimedia services in IP Multimedia Subsystem (IMS). The first authentication step is used to gain UMTS General Packet Radio Service (GPRS) network admission. The second authentication step is the IMS authentication...
Mobile Ad Hoc Networks (MANET) are a peer-to-peer communication network that can be used to transmit data using a mobile or wireless link without the support of fixed infrastructure. A literature survey highlighted that the key characteristics of efficient MANET nodes are reputation value, residual battery level and energy consumption. Various MANET algorithms and routing techniques such as location...
A goal for next generation mobile networks is to provide seamless personal mobile communication and improved quality of service (QoS). Fair, class based service and lossless handoff are a focus for improving QoS. The research presented in this paper proposes a scheduling mechanism for providing improved QoS in mobile broadband Internet Protocol (IP) high-speed downlink packet access (HSDPA) networks...
Although Bcr-Abl kinase inhibitors have proven effective in the treatment of chronic myeloid leukemia (CML), they generally fail to eradicate Bcr-Abl + leukemia cells. To identify genes whose inhibition sensitizes Bcr-Abl + leukemias to killing by Bcr-Abl inhibitors, we performed an RNAi-based synthetic lethal screen with imatinib mesylate in CML cells. This screen identified numerous...
