A novel approach for radio resource management at the base station (BS) level is introduced with the objective of improving the spectral-efficiency, while keeping the energy-efficiency (EE) at an acceptable level. In this paper, a hybrid opportunistic ON/OFF switching (OOFS) and dynamic channel allocation (DCA) mechanism is proposed. The problem is formulated as a non-cooperative game between the BSs who seek to decide on their transmission mode and channel allocation parameters. To solve this game, a two-step algorithm is proposed. At first, a mixed-strategy game is used, so the BSs may decide independently about their power management strategy. In the second step, the BS selects its downlink channel using a fully distributed channel segregation approach. In dense heterogeneous environments, the DCA algorithm shows a significant improvement in terms of BS throughput over OOFS algorithm, while keeping an acceptable EE level comparable to OOFS.","PeriodicalId":334594,"journal":{"name":"5th International Conference on Energy Aware Computing Systems & Applications","volume":"24 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-12-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115513966","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, the main problems with BCI implants are: the open wound problems, the implant size and the needed power. This limits the usability of BCI implants for patients. Therefore, a wireless VLSI approach can provide a feasible solution for medically safe and usable implants. Spike Sorting play a major role in power consumption and area within the BCI signal processing stages. Thus, this study provides a survey and an analysis of the Signal Processing and Spike Sorting methods being used or proposed for VLSL wireless BCI Implants, along with a suggested design and a set of recommendations as a step closer to real-life BCI implants.","PeriodicalId":334594,"journal":{"name":"5th International Conference on Energy Aware Computing Systems & Applications","volume":"10 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-03-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122190465","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This paper presents a new control technique based on digital current sensing. The idea is based on sensing the output current through a series resistance, the current sensor is a simple analog circuit, and it generates a pulse of width that is directly proportional to the rate of change of current. A pulse-to-digital converter is designed to convert the input pulse to a thermometer code. The code is then used to control a low supply digital controlled oscillator, it generates a clock that control the charge pump that searches for the maximum power of the solar cell. This design features a hill climbing maximum power search embedded inside the pulse-to-digital converter. A low dropout regulator with resistive ladder is used to control the supply of the oscillator, the oscillator supply is used as control knob for the frequency of the charge pump. The proposed control unit exhibits low power consumption, since it works at lower supplies than the energy buffer. The design can reach a power efficiency of 58.2% up to SmW available photovoltaic power. The measured power consumption is 36.33/iW. The system is designed using Global Foundries (GF 65nm).","PeriodicalId":334594,"journal":{"name":"5th International Conference on Energy Aware Computing Systems & Applications","volume":"93 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-03-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123818359","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The proposed schemes use randomized channel sensing, implicit cooperation, and simplified aggregation to reduce the energy consumed in channel sensing.

A well behaved model can anticipate the demand patterns and proactively react to the dynamic stresses in a timely and well optimized manner. For a workload hosting environment, pool of available resources are optimally configured and utilized to sustain certain expectation of Quality-of-Service (QoS) in the presence of power, thermal and reliability constraints. The workload (or job) scheduling mechanism is expected to withstand dynamic variations in demand stresses while maximizing the resource utilization and minimizing the performance loss. Furthermore, workloads can be co-allocated to the clusters with least amount of resource contention. In this paper we introduce the methodology that facilitates the coordinated scheduling of the workloads to the systems with least contentious resources through phase-assisted dynamic characterization. We describe the method to perform optimal job scheduling by using phase model synthesized by learning and classifying the run-time behavior of workloads.","PeriodicalId":334594,"journal":{"name":"5th International Conference on Energy Aware Computing Systems & Applications","volume":"39 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-03-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133440812","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
