“…Figure 9 shows that between the values 0.86 and 1.0 for the fading channel characteristics parameter, the energy ‡ consumed is found to be at a desired level as expected. This can also be compared with the simulation results extracted by previous researches [15,16] where approximately the values are very close. Figure 10 shows the power consumed with respect to the average throughput.…”

“…The work done in [3,5,6] determines a combination of the history traffic scheme along with an association of the behavioral promiscuous caching characteristics and storage-capacity characteristics. This work extends the work already done in [3,15,16] proposing 171 an architectural optimization of the previous frameworks by introducing the cross-layered twotier model to conserve energy. The model measures the validity and effectiveness of the newly proposed middleware and controls the mobile interfaces by minimizing the energy consumed on any asymmetrically communicating wireless link.…”

SUMMARYWireless infrastructureless networks demand high resource availability with respect to the progressively decreasing energy consumption. A variety of new applications with different service requirements demand fairness to the service provision and classification, and reliability in an end-to-end manner. High-priority packets are delivered within a hard time delay bound whereas improper power management in wireless networks can substantially degrade the throughput and increase the overall energy consumed. In this work a new scheme is being proposed and evaluated in real time using a state-based layered oriented architecture for energy conservation (EC). The proposed scheme uses the node's self-tuning scheme, where each node is assigned with a dissimilar sleep and wake time, based on traffic that is destined for each node. This approach is based on stream's characteristics with respect to different caching behavioral and storagecapacity characteristics, and considers a model concerning the layered connectivity characteristics for enabling the EC mechanism. EC characteristics are modeled and through the designed tiered architecture the estimated metrics of the scheme can be bounded and tuned into certain regulated values. The real-time evaluation results were extracted by using dynamically moving and statically located sensor nodes. A performance comparison is done with respect to different data traffic priority classifications following a real-time asymmetrical transmission channel. Results have shown the scheme's efficiency in conserving energy while the topology configuration changes with time.

Software systems that provide context-awareness related functions in pervasive computing environments are gaining momentum due to emerging applications, architectures and business models. In most context-aware systems, a central broker performs the functions of context acquisition, processing, reasoning and provisioning to facilitate context-consuming applications, but demonstrations of such prototypical systems are limited to small, focussed domains. In order to develop modern context-aware systems that are capable of accommodating emerging pervasive/ubiquitous computing scenarios, are easily manageable, administratively and geographically scalable, it is desirable to have multiple brokers in the system divided into administrative, network, geographic, contextual or load based domains. Context providers and consumers may be configured to interact only with their nearest, relevant or most convenient broker. This setup demands inter-broker federation so that providers and consumers attached to different brokers can interact seamlessly, but such a federation has not been proposed for context-aware systems. This article analyses the limiting factors in existing context-aware systems, postulates the design and functional requirements that modern context-aware systems need to accommodate, and presents a federated broker based architecture for provisioning of contextual information over large geographical and network spans

“…Figure 4 shows the parameters which affect the overall σ i and the link predicted transmission time duration. When σ i is minimized, is considered as the optimal caching parameter for minimum energy consumption [19]. The σ i parameter is a function ofδ (m) which is the promiscuous caching delay (duration in sec).…”

Effective energy conservation scheme should support the asymmetrical nature of wireless devices like capacity limitations and signal strength in an efficient end-to-end connectivity manner. Prolonging network lifetime has a major impact on the network and on the energy consumption of each device individually. This work considers an approach in which on a dissimilar-based schedules, the interfaces change their state in which the energy conservation mechanism takes place. The proposed model takes into account metrics like the signal strength and devices' capacity limitations, and encompasses them into the layered asynchronous scheduling scheme for providing end-to-end reliability and performance measures extraction. This work mainly proposes an association for controlling the power consumption parameters into a bounded limit and within a range of bounded values, measuring at the same time the critical transmitting range of each device. Through the designed two-tier architecture and layering approach, and through the experimental simulation, the proposed energy-aware management scheme is thoroughly evaluated in order to limit these parameters in terms of traffic density, storage measurements and the impact of caching on each device, into the desired values.Keywords Energy level self-control · Layered-based energy conservation · State-based energy conservation · Mobile peer to peer networks energy management scheme · Critical transmitting range of each device
