Context awareness and intelligence enable the SU to sense for and use the underutilized licensed spectrum in an efficient manner. This paper investigates various learning mechanisms for achieving context awareness and intelligence with respect to Dynamic Channel Selection (DCS) in CR networks. The learning mechanisms are Adaptation (Adapt), Window (Win), Adaptation-Window (AdaptWin), and Reinforcement Learning (RL). The DCS scheme helps SU base station to select channel adaptively for data transmission to its SU host in static and mobile centralized CR networks. The purpose is to enhance quality of service, particularly throughput and delay (in terms of number of channel switches), in the presence of channel heterogeneity. Our contribution is to investigate simple and yet pragmatic learning mechanisms for CR networks. Simulation results reveal that RL, AdaptWin and Win achieve approximately similar and the best possible network performance, followed by Adapt, and finally Random, which does not apply learning and serves as baseline.","PeriodicalId":437953,"journal":{"name":"2011 IEEE 36th Conference on Local Computer Networks","volume":"24 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-10-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115902825","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}

Although some smart meters make use of wireless data transfers between their sensor and display units, their integration into existing wireless sensor networks is hampered by proprietary communication interfaces and their lack of re-programmability. Furthermore, the sole availability of aggregate consumption values renders current meters insufficient for novel application scenarios like smart home automation, for which information at device-level granularity and high resolution is vital. We address these shortcomings of existing solutions by presenting SmartMeter.KOM, our wireless sensor node capable of determining the current consumption of individual electrical appliances at high resolution. The platform is based on low-power hardware and incorporates a reprogrammable microcontroller which allows developers to easily deploy new algorithms. Its IEEE 802.15.4-compliant radio transceiver makes its integration with existing sensor networks possible, and thus enables their integration in smart buildings. We demonstrate the versatility of SmartMeter.KOM by presenting prototypical implementations of smart applications and identifying further research directions.","PeriodicalId":437953,"journal":{"name":"2011 IEEE 36th Conference on Local Computer Networks","volume":"100 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-10-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124198349","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}

Our previous work has established the benefits of variable TDMA scheduling in this setting, where the order of communication with nodes in each TDMA round is determined on the fly by the hub, based on the actual outcomes (success or failure) of their recent transmissions. This technique takes into account the very slow fading nature of wireless channels in BANs, and can minimize the expected rate of transmission losses merely by ordering nodes according to their most recent channel state information, without any additional energy overhead. In this paper, we focus on an extended TDMA setting where the length of each TDMA round is greater than the number of nodes, i.e. a number of ‘spare’ slots are reserved for retransmissions of lost packets. We consider delay-constrained data transmissions based on a Markov model of the wireless channels. We evaluate several variable scheduling strategies in terms of the trade-off between the energy consumption due to the additional retransmissions and the reduction of the loss rate. We show how the best strategy depends on the energy budget of the sensor nodes, and demonstrate the considerable reduction in the loss rate (up to 18%) that can be achieved over a naïve approach where static TDMA scheduling is combined with retransmission slots at the end of the round.","PeriodicalId":437953,"journal":{"name":"2011 IEEE 36th Conference on Local Computer Networks","volume":"23 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-10-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114947889","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}
