Conducting this review proved difficult because the standards-track security mechanism for Mobile IPv6 is tightly integrated into the protocol; extensions to Mobile IPv6 and the core documents make assumptions about the properties of the security model without explicitly stating what assumptions are being made. There is no documented service model. Thus it is difficult to replace the security mechanism and see if the current protocol and future extensions meet appropriate security requirements both under the original and new security mechanisms. If a service model for Mobile IPv6 security is ever formally defined and reviewed, a mechanism similar to this one could be produced and fully reviewed.","PeriodicalId":143498,"journal":{"name":"2016 IEEE Online Conference on Green Communications (OnlineGreenComm)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122900218","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}

In order to relief this constraint, scavenging ambient energy from the environment has been considered. However, most existing energy harvesting devices rely on a single energy source, potentially reducing the sensor reliability. In this paper, we present an architecture for multi-source energy harvesting, aimed at low cost and easy integration with existing wireless sensors. Unlike existing architectures, our solution relies on a single power conditioning block. This block is powered by multiple sources, selected through a switch matrix by a dedicated controller. A prototype has been developed, validated and compared with alternative architectures. First results show our architecture benefits for systems using many heterogeneous sources, and highlights improvement possibilities through the addition of MPPT (Maximum Power Point Tracking) circuitry.","PeriodicalId":143498,"journal":{"name":"2016 IEEE Online Conference on Green Communications (OnlineGreenComm)","volume":"18 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-11-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130568096","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}

In this paper, we study the trade-off of users' satisfaction and grid energy consumption considering different types of traffic. Users' satisfaction of each type of traffic is represented by a utility function, as this allows for a better trade-off between energy consumption and users' satisfaction. The problem is formulated as a weighted sum of two objectives, power demand and average users utility. Then, we study the users' satisfaction and power demand considering two types of schedulers. Finally, we study the trade-off between grid energy consumption and users' satisfaction for different weightage of each of the two objectives. Results show that grid energy consumption can be reduced of up to 40% with only 6% degradation in terms of users' satisfaction.","PeriodicalId":143498,"journal":{"name":"2016 IEEE Online Conference on Green Communications (OnlineGreenComm)","volume":"86 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122532274","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 environmental energy harvesting technologies are promising solutions for alleviating the energy shortage in sensor networks. This work addresses the maximum lifetime target coverage problem in energy harvesting directional sensor networks. In this problem, the coverage quality requirements of all targets should be continuously satisfied and the network connectivity should be guaranteed. It is very challenging due to the limited sensing angle and the recharging ability of the sensors, and the different coverage quality requirements of the targets. We prove its NP-hardness and formulate it as a mixed integer nonlinear programming model. Two heuristics are proposed to solve it.

The channels experience both small and large-scale fading. For large numbers of users, we introduce User Selection and Group Selection schemes, to keep the number of users less than or equal to the number of relay antennas in each group, with the goal of improving system performance.

The main advantage of a light trail over a light path is that the communication channel of a light trail can be accessed by intermediate nodes providing more flexibility for traffic grooming. In general, energy consumption in an IP-over-WDM network is dominated by optical-electronic (OE) and electric-optical (EO) conversion operations and related router processing. This paper addresses the issue of minimizing energy consumption of OEO conversion operations in designing light trails for traffic grooming purpose in light-trail optical WDM networks.

However, in case of contingencies in the energy system when the guaranteed peak load reduction is needed, comfort of consumers can be significantly deteriorated and they can choose to opt out. This paper investigates the possibility of peak load reduction and yet highly respecting consumers' comfort by coordinating a group of electric tank water heaters. The proposed peak shaving mechanism accounts for interests of both utility companies and their customers. It employs two optimization models tailored to the needs of both sides to optimally schedule individual water heaters. The suggested Simulation results show the potential of the proposed mechanism to provide the guaranteed peak load reduction thus contributing to the stability of the electrical grid, while transparent balancing between comfort-money and comfort-energy incorporated in the control scheme is of interest and use to green consumers.","PeriodicalId":143498,"journal":{"name":"2016 IEEE Online Conference on Green Communications (OnlineGreenComm)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131208217","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}

Due to the content-centric nature of future wireless communications, it is desirable to cache popular contents beforehand at the RRHs, to reduce the burden on the fronthaul and achieve energy saving through cooperative transmission. This motivates our study in this paper on the energy efficient transmission in an orthogonal frequency division multiple access (OFDMA)-based CRAN with multiple RRHs and users, where the RRHs can prefetch popular contents. We consider a joint optimization of the user-SC assignment, RRH selection and transmit power allocation over all the SCs to minimize the total transmit power of the RRHs, subject to the RRHs' individual fronthaul capacity constraints and the users' minimum rate constraints, while taking into account the caching status at the RRHs. Although the problem is non-convex, we propose a Lagrange duality based solution, which can be efficiently computed with good accuracy. We compare the minimum transmit power required by the proposed algorithm with different caching strategies against the case without caching by simulations, which show the significant energy saving with caching.","PeriodicalId":143498,"journal":{"name":"2016 IEEE Online Conference on Green Communications (OnlineGreenComm)","volume":"474 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133143054","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}
