It is expected to become a cost-effective solution for improving the communication performance of indoor users, whose traffic demands are large in general. There are mainly two access strategies for femtocell, i.e., closed and open access strategies. While it has been known that open access femtocells contribute more to enhancing the system-wide performance than closed access femtocells, the performance of open access femtocell owners can be potentially degraded when sharing their BSs with other macrocell users. To prevent this potential problem, we develop a load balancing scheme which maximizes the average throughput of macrocell users while guaranteeing some degree of benefits to femtocell owners. To achieve this goal, we jointly optimize the ratio of dedicated resources for femtocells as well as the femtocell service area via an analytic model, which proves that the optimization is a convex optimization problem in the typical environments. Our analysis and simulation results show that the proposed load balancing scheme significantly enhances the system-wide performance.","PeriodicalId":72021,"journal":{"name":"...

The optimization aims to minimize the energy required for the successfully delivery of one information bit from a transmitter to a receiver. The design is performed by incorporating a wide range of practical system parameters and metrics, such as hardware power consumption, modulation, channel coding, and frame error rate (FER) in the physical layer, and frame length and protocol overhead in the media access control layer. A new log-domain threshold approximation method is proposed to analytically quantify the impacts of the various system parameters on the FER, and the results are used to facilitate the system design. The optimum transmission energy and frame length that minimize the energy per information bit are identified in closed-form expressions as functions of the various practical system parameters. The analytical and simulation results demonstrate that the total energy consumption in a coded ARQ system can be reduced by increasing the transmission energy during one transmission attempt, and significant energy saving as high as 9.5 dB is achieved with the optimum system.","PeriodicalId":72021,"journal":{"name":"...

In this paper we present deStress, the mobile and remote stress monitoring, alleviation and management system, whose features are: firstly it is wearable and inexpensive, which uses only one wearable stress monitor sensor and a mobile phone-based application (Android OS) to monitor stress. Secondly, deStress quantitatively assesses the user's stress level continuously, not just classifies the users into stressed or non-stressed state. Thirdly, deStress provides a system for stress monitoring and management, through which the stress data could be recorded, analyzed and shared with medical professionals. Last but not least, a novel adaptive respiration-based bio-feedback approach is implemented to alleviate stress. To the best of our knowledge, deStress is the first telehealth system dedicated to mobile and remote stress monitoring, alleviation and management. Extensive experiment are conducted in 30 persons to demonstrate the feasibility and effectiveness of deStress, and the result shows that the stress level assessment of deStress correctly indicates the mental states of the users, and under the guidance of deStress the users could alleviate their stress level dramatically.","PeriodicalId":72021,"journal":{"name":"...

An energy-per-goodbit (EPG) metric is used to gauge the average energy consumed for transmitting each bit. Existing works minimize EPG by searching for a set of dual variables which are used to compute the optimal power allocation in a Water-Filling (WF) expression. The searching process is complex and requires a long running time. In this paper, we propose a new algorithm to compute the optimal power allocation without searching any dual variables. Our algorithm is based on an iterative calculation of the total transmission power and it converges when the minimum EPG is reached. It takes WF as the basic building block. Unlike the conventional WF approach which needs to search for a Lagrange multiplier (i.e., the water level), we additionally propose a novel WF algorithm without searching the Lagarange multiplier. Numerical results show that our power allocation algorithm for EPG minimization, together with the embedded fast WF algorithm, can run multiple times faster than the existing ones.","PeriodicalId":72021,"journal":{"name":"...
