Special Issue on Ubiquitous Computing and Future Communication Systems In contemporary, the proliferation of wearable and personal technologies available to access to the networks has become significant [1–3]. It is obvious that the rise of these technologies is the thrust of the ubiquitous computing and communications. Ubiquitous computing promises to have a profound effect on the way the people interact with de electronic devices. Since the paradigm emerges, we have witnessed the advent the revolutionary computing technology. Ubiquitous computing is an enabler of hundreds of thousands of devices, such as embedded systems, computers, digital communication equipment and electronic sensors that will deliver new functionality, novel ways of interaction, and also dedicated services. Nowadays, utilization of smaller devices has become a trend. Communication and services are going mobile. Each tiny smart object is connected together into networks and interacts with their handlers. These raise serious issues to the provisioning of the stateof-art ubiquitous computing and future communication technologies. In order to fulfil the challenges, new ubiquitous computing paradigm related solutions become an increasingly pressing demand. Issues need to be addressed in this special issue include the following:
• The open issues in cloud computing can be addressed by ubiquitous computing. In this context, solutions are needed with the aim of facilitating the paradigm. • Limited service resource shared by the communication devices is a growing concern. The provisioning of quality of service (QoS) or even quality of experience (QoE) has been an impressing demand. Prediction and measurement of shared medium in terms of QoS or QoE provide performance-aware operations, designs and directions in future communication systems. • Stochastic and unpredictable wireless channel features always lead to uncertainty. As a result, availability and utilization of wireless devices and the communication among them can hardly be guaranteed. To this end, novel wireless technologies combing ubiquitous computing are required to improve the aforementioned issues. • New paradigms, such as context-aware applications, cognitive radio, software defined networks and smart city, promise the developments but usher new challenges into the area. Innovative solutions are necessary to provide efficiency, feasibility and availability in these emerging contexts. Although some of the aforementioned have attracted attention from both the academic and industrial community, many issues are yet to be addressed. This special issue of the Ubiquitous Computing and Future Communication Systems aims at highlighting the challenges and potential solutions of ubiquitous computing and http://dx.doi.org/10.1016/j.future.2014.05.003 0167-739X/ © 2014 Published by Elsevier B.V.
future communication related topics. Thanks to the Editor-inChief, we are able to accept some more papers that reflect stateof-art research trends in this area. The topics in this special issue range from energy-aware issues in cognitive radio networks, smart homes, wireless sensor network subjects and load balancing in Internet. The papers are organized as follows. The first article is a Graph-based Approach for Interference Free Integration of Commercial Off-the-Shelf Elements in Pervasive Computing Systems by Christophe Soares, et al. [4]. This work introduces the integration of commercial off-the-shelf devices and applications in massive deployment of pervasive computing technology in home settings. The authors have demonstrated and discussed graph-based approach for representing the expected behaviour of commercial devices and applications for detecting interference. In addition, this paper has validated their work with home care scenarios. The second paper is A Resource Intensive Traffic-Aware Scheme using Energy-Aware Routing in Cognitive Radio Networks by Constandinos Mavromoustakis, et al. [5]. Cognitive Radio Networks and Opportunistic spectrum access is a promising dynamic spectrum management method which enables the coexistence of primary users and secondary users. This paper develops a resource intensive traffic-aware scheme, incorporated into an energy efficient routing protocol. Experimental simulation tests have been used to verify the proposed schemes. The performance evaluation results suggest the feasibility of the scheme. The third paper, Combining Ontological and Temporal Formalisms for Composite Activity Modelling and Recognition in Smart Homes, is authored by George Okeyo, et al. [6]. Activity recognition is essential in providing activity assistance for users in smart homes. This paper introduces a combined ontological a temporal approach to composite activity modelling and recognition by extending existing ontology-based knowledge-driven approach. The authors have applied the method upon a prototype system for testing and evaluation. The fourth paper, Energy Efficient Indoor Tracking on Smartphones [7], demonstrates an indoor location approach. The authors develop an indoor tracking framework which determines the location data and meanwhile achieves the goal of energy efficiency. The authors applied the approach on smart phones and obtained the evaluation results from a real testbed. This group contains three papers which are aiming at solving the mapping problems in Internet, evaluating the applicationbased TCP for very long baseline interferometry in long distance networks, and optimizing the selection method for joint network in cooperative wireless networks. Fast Dynamic Internet Mapping authored by Ayman Kayssi, et al. [8], introduces a profile based strategies combining load balance to examine the routing changes.

The authors have applied the methodology on the Internet. The experimental results show the time cut in probing and scanning the path. The Design and Evaluation of Application-based TCP for e-VLBI in Fast Long Distance Networks is authored by Yulei Wu, et al. [9]. This work develops an application based TCP congestion control algorithm, using closed-loop control theory to maintain the transmission performance. The authors further conduct experiments in real testbed and validate the proposed method. The last paper in this group is User Adaptive QoS Aware Selection Method for Cooperative Heterogeneous Wireless Systems: A Dynamic Contextual Approach [10]. This paper authored by Haris Pervaiz, et al. presents an optimization utility to incorporate the QoS dynamics of the networks with heterogeneous attributes of users. The evaluation results obtained by simulation suggest the correctness of the proposed methodology. Last but not least, three papers are classified into this group. The works in this group focus on various issues in wireless sensor networks. Auction-Based Adaptive Sensor Activation Algorithm for Target Tracking in Wireless Sensor Networks authored by Guojun Wang et al. [11], introduces an algorithm for monitoring and tracking moving targets in wireless sensor networks based on adaptive sensor node activation. The testing results are obtained in light of simulations. Delay Characterization and Performance Evaluation of Cluster-Based WSN with Different Deployment Distributions is authored by Uthman Baroudi et al. [12]. This work discusses the impact of different sensor nodes deployments and characterized the routing behaviour. Further, the paper investigated the cluster formation effect on the system delay which includes inter-cluster delay and intra-cluster delay. Finally, the performance results suggest the efficiency of the proposed approach. The last paper in this group entitled Efficient Code Dissemination in Wireless Sensor Networks introduces a code dissemination protocol which aiming at leveraging the properties of Trickle and Varuna code dissemination protocols [13]. The results suggest that the proposed code dissemination outperforms the existing code dissemination in various aspects.
