    The Help4Mood EU FP7 project (H4M) [1] proposes to significantly advance the state-ofthe-art in computerized support for people with Major Depression by monitoring mood, physical activity and voice characteristics while promoting activities in reaction to examined inputs. Employing actigraphy can provide supplementary data about patients with depression. Nonetheless, its use is not standardized and there is a lack of public analyses about treated patients with depression using this technique, which is the objective of the project. The purpose of the Personal Monitoring System (PMS) used in H4M is to compile objective data about the changes and trends of activity patterns during long periods of time. This would comprise daily activity, rest time and, if possible, sleep quality. The PMS uses inconspicuous methods but keeping the cost associated with sensor installation at the patient¿s home to a minimum. This work focuses on the Wireless Sensor Network (WSN) enhancements introduced after real testbeds and considering User Quality of Experience (QoE), mainly oriented to reduce energy consumption and required data transmission and consequently improving the autonomy and range of the sensors.

    Help4Mood aims to develop a platform to support the treatment of people with depression in their own home. Depression is one of the main causes of disability worldwide. For depression, it is essential to have a continuous control in order to check the patient status and avoid relapses. Thus, we propose Help4Mood, which is designed as a Personal Health System. It consists of a set of different wireless sensors whose data sink is centralized on a laptop and it is administered by a clinician that supports the treatment of depression. The outcome of the platform is available to the clinician in order to check the patient's status during the periodic appointments. The use of standards contributes to improve care delivery, optimize workflow and reduce ambiguity. For this reason Help4Mood is able to communicate with the Healthcare Provider using the standard of communications protocol Health Level Seven (HL7). In this work, we describe the main components, principal features of the Help4Mood and the results from the evaluation of the activity monitoring system on patients who had recovered from depression in Catalonia, Scotland and Romania. Updates caused by the results of the evaluation in the design of Wireless Sensor Network are included.

    Help4Mood is a closed loop approach supporting the control, communication and treatment management of patients with Major Depression. The first out of the three main components of the Help4Mood solution is the Personal Monitoring System (PMS), a set of different wireless sensors whose data sink is centralized on a laptop. The objective of this PMS is to monitor the activity of the patients, so several sensors have been chosen to cover the needs of different individuals. These include a wrist watch, a key ring, a waist/belt sensor, an under mattress sensor and a cellular phone. This paper describes the first prototype and the results obtained from this Wireless Sensor Network

    Help4Mood is a project inside 7th European Framework Programme (FP7) for developing a computational distributed system to support remotely the treatment of patients with major depression at home. Core components are integrated with the ICE framework. One of the main goals of this system is to use the paradigm of a Virtual Agent to support the first symptoms of clinician alert of a patient, to interact with him an to prevent some causes of relapse after monitoring he/she with different sensors. The system processes inputs from different devices for monitoring patient activity at home and how he/she sleeps (also know as the Personal Monitoring System), transmitting this data to a Decision Support System, and defining how a Virtual Agent should interact with the patient before clinical support from hospital is needed if an alert is detected. This data is transmitted by a wireless network designed to improve data communication from sensors in a home environment (easy of installation and maintenance) and implemented using customized protocols and algorithms for reducing power consumption of these sensors. The technical framework is using open source implementations of ICE and HL7-standard-based healthcare integration engines to interact with the different subsystems. Particularly, the use of these standards will contribute to commercialization of the project results and the potential impact through the development, dissemination and use.

    The research involved in this study comprises the analysis of the impact of the power control algorithm and its performance in the system level. Following our work in TD 01040, the LTE system level simulator has been equipped with a power control block that enables interference management at the same time that controls the fairness among users. Rising from the fact that it is very sensitive to the environment, the algorithm is tested in two different scenarios in a comparative way. First, the conventional synthetic scenario, with regular hexagonal base stations distribution, and then a piece of the scenario of Vienna, developed during the COST 273 action in the MORANS initiative. This dissimilarity in simulation environment leads to strong differences in the system performance. Results show how the real scenario is not so sensitive to interferences and so that the major issue is the availability of transmission power at the cell edge.

    This paper presents an efficient multipolling scheme that improves the IEEE 802.11 MAC protocol efficiency and does not suffer from the hidden terminal problem or inefficient channel usage problems. To design an efficient polling scheme, the access point (AP) needs to obtain information about the current transmission status and channel state for each station. In this new scheme, we propose the use of multipolling frames in the downlink and Orthogonal Frequency Division Multiple Access (OFDMA) for the uplink reservation frames in order to reduce signaling overhead.
