Among the trends in ICT is virtualization in order to find ways to reduce the amount of dedicated resources needed for an individual computer user. The non-stop increase in data generation will require us to have more and more storage devices. Although these devices are becoming less expensive, they still need power to operate them and mechanisms to cool them. It is expected that providing applications via mobile tools will continue growing rapidly. This will entail more server capability and rise in the demand for computing power in data centers. This is also a potential area for virtualization. Due to virtualization and integration, data centers are now able to push more into a rack. This has lead to an increase in the power consumption per square foot by a factor of 10 or so. Cloud computing is becoming more and more popular as it provides scalable and resilient IT-enabled resources using the Internet means.

In addition to the trends and challenges in green ICT, we will be presenting some of our related research works. We propose a Dynamic Energy Efficient and Secure Routing Protocol for Wireless Sensor Networks in Urban Environments, DEESR. A decision is made by every node based on various parameters like longevity, distance, and battery power, which measure the node and link quality to decide the next hop in the route. This ensures that the total load is distributed evenly while conserving the energy of battery-constrained nodes. The protocol also maintains a trusted population for each node through Dynamic Trust Factor (DTF), which ensures secure communication in the environment by gradually isolating the malicious nodes. The results obtained show that the proposed protocol when compared with other energy efficient protocols such as the MMBCR and DSR gives far better results in terms of energy efficiency. We also introduce an Efficient Reactive and Angular �Optimized Link State Routing (ERA-OLSR) for MANETs. It is observed that ERA-OLSR performs better than both AODV and DSR in terms of end-to-end delay and average energy consumed. ERA-OLSR is best suited for dense scenarios. The simulation results obtained after implementing the proposed protocol have shown that ERA-OLSR has better performance than both AODV and DSR in terms of End-to-end delay and Average Energy Consumption.

We use the ideas of naturally occurring ants�foraging behavior and based on such ideas we design an energy-aware routing protocol, which not only incorporates the effect of power consumption in routing a packet, but also exploits the multi-path transmission properties of ant swarms and, hence, increases the battery life of a node. The efficiency of the protocol with respect to some of the existing ones has been established through simulation analysis. We formulate the sensor recharge problem in wireless sensor networks with rechargeable sensor nodes as a Markov Decision Processes (MDP) problem and have formulated policies to find at which level recharging is optimum. We offered a generalized formula for calculating the delay of recharge. The theoretical as well as the simulated recharge delay are compared for different policies to get the optimum one. Other related research efforts by our group will be presented.

After 35 years of scaling CMOS, today silicon devices�power dissipation is limiting the performance across the entire spectrum of computing platforms from handheld consumer devices to workstations, and to mainframes and high performance computers (HPC). While the tradeoff between power and performance is well recognized, most recent studies focus on either low-power, low-performance systems or high-power, high-performance systems. The IBM Blue Gene HPC platform started a trend by concentrating instead on a low power, high performance designs. An order of magnitude improvement in power efficiency can be attained without system performance loss in parallelizable applications �those in which such efficiency is most critical. In this talk, solutions for the key components of an HPC are discussed, using the IBM Blue Gene system as a case study to illustrate practical low power directions. From the current petascale HPC systems to the future exascale designs, power reduction will demand even more holistic tradeoffs in device technologies, computer architecture, system software and applications. This talk addresses the fundamental issue of reducing dissipation in the active mode, which is particularly relevant to applications in high performance computing with a high activity factor.

Green computing is a hot topic in these years and has attracted many researchers to focus on some typical issues, including energy saving problems in operating system and network transmission system. Now, with the development of virtualization technologies, system software has different layer concept (including physical machine, VMM and several VMs), which will make the traditional energy saving technologies invalid. For example, in client virtualization, different VMs have different energy saving decisions in their operating systems, which have conflict in VMM layer. But, on the other side, virtualization technologies can build a promising energy saving framework for data centers with the help of VM migrations in easier way than ever. So, it is important to find out the impact of virtualization technologies on computer systems and build a green map. Here, we will give our understanding on the problem and report some research experiences on green virtualized systems.
