Energy saving is a critical issue for MANET since most mobile hosts will operate on battery powers. A cross layer coordinated framework for energy saving is proposed in this letter. On-demand power management, physical layer and medium access control layer dialogue based multi-packet reception, mobile agent based topology discovery and topology control based transmit power-aware and battery power-aware dynamic source routing are some of new ideas in this framework.展开更多

Due to their inherent nature universities have a considerable impact on the environment. In this research a test was devised and completed for a sample of Australian universities to analyze the current environmental management practices of the universities over several key areas including: energy management, water management, waste management, transportation, biodiversity and sustainable development. It was discovered that in terms of environmental management universities are currently not performing at a level that is consistent with social and political expectations. In the assessment it was observed that universities have taken it upon themselves to improve to rectify this with many improvements to their current environmental management practices currently under development.展开更多
