Software reprogramming enables users to extend or correct functionality of a sensor network after deployment, preferably at a low cost. This paper investigates the improvement of energy efficiency and delay of reprogramming, at low resource cost. As enabling technologies data compression and incremental updates are used. Algorithms for both approaches are analyzed, as well as their combination, applied to resource-constrained devices. All algorithms are ported to the Contiki operating system, and profiled for different types of reprogramming. The presented results show that there is a clear trade-off between performance and resource requirements. Furthermore, the best reprogramming approach depends on the type of update. Experimentally, VCDIFF, or the combination of Lempel-Ziv-77/FastLZ for compression with BSDIFF for delta encoding, have been identified as the best possible options.

Despite the huge prospects of pervasive social computing and the extensive work in context-aware applications, so far very limited work has focused on socially-aware applications. The key requirements to develop such applications are modeling, managing and reasoning about users' social contexts. To fulfil these requirements, in this PhD research, we have made an attempt to model, manage and reason about social contexts to aid the development of socially-aware applications. We study different types of social contexts, their use in various socially-aware applications and possible sources to acquire such social contexts. We will investigate existing context modeling and reasoning techniques and will propose an approach to modeling and reasoning about different types of social contexts. To aid the development of socially aware applications, we will provide a middleware platform for managing the acquisition, changes and provision of social contexts.

We present a technique for detecting floor changes in an indoor environment and improving pedestrian indoor localization and navigation. Our technique relies on barometric pressure sensors commonly available on smartphones and tablets. We developed an algorithm running on smart mobile devices that can be integrated in any indoor localization system to improve accuracy and support 3D navigation. The main novelty of our technique is that it can work in any type of environment, without any prior knowledge of the building layout, it does not require calibration and it is adaptive. Experimental results show that our method can accurately detect floor changes in any condition without requiring any additional work.

Comprehensive communication in cognitive radio networks is an important research topic within the scope of empowering cognitive radio functionality in beyond-4G mobile networks. Providing communication for secondary users without interference with primary users is an ambitious task, which requires innovative management architecture designs and routing solutions. Operational challenges such as opportunistic spectrum access, solving problems related to spectrum and network heterogeneities and requests for the provisioning of Quality-of-Service to different applications must be resolved. As part of a novel management architecture, the paper advances a new approach to end-to-end communication in cognitive radio networks based on combining ad-hoc algorithms with spectrum mobility algorithms.

Rapid increase in number of vehicles on the roads as well as growing size of cities have led to a plethora of challenges for road traffic management authorities such as traffic congestion, accidents and air pollution. The work presented in this paper focuses on the particular problem of traffic management for emergency services, for which a delay of few minutes may cause human lives risks as well as financial losses. The goal is to reduce the latency of emergency services for vehicles such as ambulances and police cars, with minimum unnecessary disruption to the regular traffic, and preventing potential misuses. To this end, we propose to design a framework in which the Traffic Management System (TMS) may adapt by dynamically adjusting traffic lights, changing related driving policies, recommending behavior change to drivers, and applying essential security controls. The choice of an adaptation depends on the emergency severity level announced by the emergency vehicle(s). The severity level may need to be verified by corresponding authorities to preserve security measures. We discuss the details of our proposed framework and the potential challenges in the paper.

The process of inversion, estimation and reconstruction of the sensor quality matrix, allows modeling the precision and accuracy, and in general the reliability of the model. When the sensor data ranges are not known a priori, current systems do not train on new data samples, rather they approximate based on the parameter's global average value, losing most of the spatial and temporal features. The proposed model, which we call SPOTLESS, checks the spatial integrity and temporal plausibility of streams generated by mobility patterns due to varying channel conditions. We define a minimum quality of the measured sensor data as local stream (QoD) requirements to give high precision by using distributed labeled training. In our SPOTLESS datacleaning steps, to account for packet errors due to varying channel conditions, a soft-phy based decoding is selected for various Bit Error Rates (BER), minimizing packet loss at the mobile receiver. Numerical experiments for Rayleigh fading channels and mobile BER model examples are compared with large deployment of ground sensor collecting static data streams and Data MULE collecting multi-hop temporal data from the sensor to provide hypothetical parameter accuracy. Our results were obtained in the context of provisioning a minimum precision and accuracy stream (QoD) required for 802.15.4 mobile services. SPOTLESS data-cleaning algorithm coding provides 90% precision for static streams, and increases the plausible relevance of multi-hop mobile streams by 85% for task-based learning.

This paper describes the work in progress of converting context to indoor position using built-in smartphone sensors. This research will ultimately contribute towards a self-sufficient indoor positioning system that works without any interaction with a pre-deployed communication infrastructure. Such selfsufficiency is desired from several points of view. It makes the system more scalable, privacy-preserving (no communication means less chances of privacy leakage), and energy-efficient (radio interfaces consume orders of magnitude more energy than MEMS sensors, such as accelerometers).

Emergency response operations are a promising application area for mobile ad-hoc networks (MANETs). Most existing MANET routing protocols assume that an end-to-end path between source and destination can be established. However, this assumption may not hold in a hastily formed network established during an emergency response. This paper evaluates a store-and-forward mechanism for proactive routing protocols to mitigate the effects of network disruptions. The mechanism is integrated into two routing protocols. The modified protocols are evaluated in an emergency response scenario that includes a disaster area mobility model and a wireless obstacle model. The scenario represents a realistic first responder operation after an incident in a chemical facility. The evaluation results show that networks for disaster responses benefit from the modified routing protocols.

Wireless sensor and actuator networks (WSAN) have become pervasive and are found in many embedded and intelligent systems. However, the complexity of applications based on WSANs is limited due to the lack of programming tools for this type of networks. In this paper, we show how a concurrent programming language, SystemJ, is used to develop a middleware-free distributed system that consists of a combination of stationary and mobile WSAN nodes. A distributed Ambient Intelligence (AmI) monitoring and control scenario that consists of collaborating stationary and mobile WSAN nodes with high degree of reactivity is presented. The system is designed and implemented using SystemJ to demonstrate the proposed system-level design approach. SystemJ is designed specifically to handle reactive and concurrent behaviors while providing modular and scalable methodology for distributed system composition. In addition, SystemJ removes the need for a middleware and allows system designers to focus on implementing system functionality rather than to deal with the low level programming details.

Micro-Volunteering is the phenomenon of volunteering one's time and energy for extremely short periods of time. It is often considered a subset of Virtual Volunteering where one can volunteer one's time and energy via the Internet. There are many successful examples of Virtual Volunteering such as the Gutenberg project and the Librivox project. However, in both these cases, a volunteer must donate a substantial amount of his or her time in activities such as reading books or proofreading books. This paper examines the concept of synchronous micro-volunteering where potential volunteers can effectively donate as little as 10 minutes of their time and immediately assist other people. The paper then describes the architecture which supports synchronous micro-volunteering.
