However, ambient energy sources typically exhibit temporal-spatial variation, and complex power management algorithms have been proposed to model and adapt to variation and achieve energy-neutral operation. However, existing algorithms are limited in the scale of spatial variation that they can accommodate, as they are restricted by the physical boundaries of the network. This paper proposes Opportunistic Energy Trading (OET) to overcome this limitation, and allow networks to trade energy to neighbouring networks which may either be heavily energy-constrained or else suffering from a temporary drought of harvested-energy. To show the potential of OET, we present a case study consisting of an energy-constrained battery-powered WSN which neighbours an energy-harvesting WSN. The case study considers a simplified version of OET, whereby the harvesting WSN transfers (i.e. trades for free) its excess energy to the constrained WSN in order to extend its lifetime. The case study is evaluated through simulation, and shows that the lifetime of the energy-constrained network increases by 40% while the effects on the harvesting network can be considered insignificant.","PeriodicalId":155579,"journal":{"name":"ENSSys '13","volume":"47 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-11-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130816758","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}

An energy harvesting solution utilizes vibrational, thermal and light energy as the power supply for the AE wireless sensor node. The multiple-source energy harvester proposed in this work generates 1.56mW from 25--48mg vibration energy and 3.37mW from thermoelectric energy when deployed on the 62°C metal surface of air compressor.

This paper presents a circuit designed to improve the efficiency of the rectifying stage combining a MOSFET-based active rectifier in parallel with a passive full-wave bridge. Such system exploits the low forward voltage of the Schottky diodes to compensate the drawback of the inefficient passive rectification due to the bulk diodes of the MOSFETs when the power generated by low air-flow speed is not sufficient to activate the control circuitry of the active rectifier. The hybrid rectifier concept was firstly analyzed by SPICE simulations and next validated by means of experiments. Results show a conversion efficiency improvement between 10% and 30%. Moreover an energy harvester equipped with the hybrid rectifier shows an increase of the collected energy from 7% to 11% with respect to a scavenger using the active topology.","PeriodicalId":155579,"journal":{"name":"ENSSys '13","volume":"205 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-11-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131992654","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}
