However, the 6LoWPAN link [2] is characterized as lossy, low power, low-bit-rate, and short-range communications. It is common with such constraints that many nodes attempts to save their energy through long sleeping periods. This paper presents a novel deployment strategy for a self-sustained network of IPv6 devices. The major focus is on the optimization of the communication protocol stack for Wireless Sensor Networks (WSN) to support nodes on sleeping mode. Recently, significant efforts have been made towards the standardization of the IoT protocol stack [3], which mostly has been implemented on the popular Contiki operating system. The protocol stack has been enhanced by implementing an optimized version of the Neighbor Discovery Protocol [4]. The usage of the Contiki MAC Radio Duty Cycling Protocol notably reduces and improves the energy consumption of network nodes. In our deployment prototype, each node is equipped with a rechargeable battery and a small solar panel to harvest the ambient light while performing measurements. Preliminary results demonstrate that the proposed node architecture and protocol stack optimization provide 15x fold of energy saving compared to base architecture with no stack optimization.","PeriodicalId":6609,"journal":{"name":"2018 International Flexible Electronics Technology Conference (IFETC)","volume":"30 4 1","pages":"1-2"},"PeriodicalIF":0.0,"publicationDate":"2018-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"77481263","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}

A five-stage RO has been implemented with different inverter topologies using IGZO TFTs, which includes Diode connected load, Capacitive bootstrapping (BS), Pseudo-CMOS and Pseudo-CMOS bootstrapping architectures. These topologies have been simulated using in-house IGZO TFT models under similar conditions using different power supplies (10 V, 15 V and 20 V) in cadence environment. Among all architechtures Capacitive bootstrapping RO has ensured highest frequency of operation in the order of MHz and an output swing of 82% of VDD. Whereas, Pseudo-CMOS based RO provides the lowest power consumption in the order of μW with an output swing of 57% of VDD. On the other hand, the combination of Pseudo CMOS and bootstrapping has ensured highest voltage swing of 95% of VDD. In terms of power delay product (PDP) BS RO is superior with respect to other topologies. This work provides a clear insight to the designer to choose a particular topology for given application, mainly for on-chip clock generation for flexible electronic systems based on the requirements.","PeriodicalId":6609,"journal":{"name":"2018 International Flexible Electronics Technology Conference (IFETC)","volume":"17 1","pages":"1-6"},"PeriodicalIF":0.0,"publicationDate":"2018-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"81754779","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}
