Energy Efficiency as Input for Context-Aware Group-Based Communications

چکیده
Heterogeneity will prevail in Future Networks at many technology levels, including devices, access networks, services and applications. Moreover, the exponential proliferation of mobile computing has been followed by concerns and research efforts regarding a sustainable development of wireless systems, specially related with energy efficiency. The envisioned future networking environments will be able to build a very rich source of information that can be wisely used, not only to improve users’ service perception, but also to enhance network performance at different perspectives (e.g., quality of service, resource management and energy consumption). We believe that this is the main reason behind the increasingly popular concept of context-awareness. Current context-driven architectures aim to provide a platform to enable personalized services and smart networking, adapting contents and the way they are delivered to the users according to their particular context (device, available energy and preferences) and the network and environment context (location, technologies and energy consumed). However, given the proliferation of group-based communications and consequent traffic demands, we show in this paper how context information, including energy-related context, Journal of Green Engineering, 329–353. c © 2011 River Publishers. All rights reserved. 330 N. Coutinho et al. may influence content delivery to users, employing the information available to create groups of users according to their common capabilities. This way, we aim to achieve a higher level of personalization in multiparty services, improving users’ quality of experience. Through a service-aware group-oriented content delivery framework, we employ algorithms for core and access network selection that are flexible enough to be guided by any constraint. The developed selection scheme uses context information from user, network and environment to decide, among the available networks, the most suitable one regarding its communications needs and optimizing network constraints, such as quality of service provided and energy required. The outcomes obtained through the simulation of the proposed framework show that context-based grouping and network selection are able to improve the users’ quality of experience.

متن کاملContext-aware Modeling for Spatio-temporal Data Transmitted from a Wireless Body Sensor Network
Context-aware systems must be interoperable and work across different platforms at any time and in any place. Context data collected from wireless body area networks (WBAN) may be heterogeneous and imperfect, which makes their design and implementation difficult. In this research, we introduce a model which takes the dynamic nature of a context-aware system into consideration. This model is con...

متن کاملEEQR: An Energy Efficient Query-Based Routing Protocol for Wireless Sensor Networks
Routing in Wireless Sensor Networks (WSNs) is a very challenging task due to the large number of nodes, their mobility and lack of proper infrastructure. Since the sensors are battery powered devices, energy efficiency is considered as one of the main factors in designing routing protocols in WSNs. Most of energy-aware routing protocols are mere energy savers that attempt to decrease the energy...
