The results are based on measurements in an anechoic chamber using a vector network analyzer. Three antenna types are used: prototype dipole and double loop antennas together with the commercial Skycross antenna. The antennas are attached horizontally at the chest level and the waist level at in total 12 locations. Path loss values are defined from the first arriving paths of the channel impulse responses. Path loss models are developed for upper and lower horizontal body levels separately and for all available channels when also the cross channels between the levels are considered. The path loss exponents vary between 9.2-12.7 being clearly a higher result than previously reported. The double loop antenna has the lowest exponents and the commercial antenna the highest ones. No clear difference can be noted between the body and waist levels or when observing all channels. The scattering term of the path loss can be modeled with the generalized extreme value and generalized Pareto distributions.","PeriodicalId":333786,"journal":{"name":"2017 11th International Symposium on Medical Information and Communication Technology (ISMICT)","volume":"19 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126475494","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}

Finite integration technique (FIT) has shown to be promising method for modeling channels characteristics in WBAN deployment scenarios. Applying simulation based channel modeling on the performance evaluations of the concrete-surrounded use scenarios have not been presented in the literature. In this paper, FIT-based channel modeling is applied on the performance evaluation of IEEE 802.15.6 based energy detector (ED) receiver designed for monitoring the symptoms of Parkinson’s disease. The first aim of this paper is to assess and compare the simulated channel impulse responses (CIRs) with the data from a measurement campaign. The second aim is to apply the simulated channel on the performance evaluations of the IEEE 802.15.6 based ED receivers. The obtained bit error rate (BER) performances are compared with BERs obtained using channel measurement data in the simulations. It is shown that performance obtained using FIT-based channel modeling corresponds to performance obtained using channel measurement data based channel modeling. The results of this paper further verify the statements that FIT is sufficiently applicable for WBAN channel modeling.","PeriodicalId":333786,"journal":{"name":"2017 11th International Symposium on Medical Information and Communication Technology (ISMICT)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124390774","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 general for healthcare applications, the batteries of biosensor nodes cannot be easily recharged or replaced. Therefore energy consumption is a critical issue in WBSNs, specifically, the nodes that are placed next to the sink node consume more energy, which limits the network lifetime because all biomedical packets are aggregated through these nodes forming a bottleneck zone. Therefore, this paper proposes a novel mathematical model for body area network (BAN) topology to explain the deployment and connection between biosensor nodes, simple relay nodes, network coding relay nodes and the sink node. The model uses Random Linear Network Coding (RLNC) to improve the energy efficiency for biosensor nodes in the WBSN bottleneck zone, combining saving energy with achieving the delivery of data if there is a failure in one of the links of the transmissions. A mathematical model for a WBSN was designed, and it was apparent that energy consumption is reduced and data delivery achieved with the proposed mechanism. This paper details the stages of the research work.","PeriodicalId":333786,"journal":{"name":"2017 11th International Symposium on Medical Information and Communication Technology (ISMICT)","volume":"12 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"117053587","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}

Densely– located nodes attached to exercisers transmit heart–rate data to a data collection node simultaneously, which negatively affects the reliability of data collection due to severe congestions caused by excessive traffic load. In order to solve this problem, we introduce a heart–rate data transmission control scheme where the sensed heart–rate is transmitted only when each node detects a larger variation than a fixed threshold. In order to analyze trade– off between the traffic suppression and increased sensing error through the introduced threshold, we first conduct experiments to obtain heart–rate variations during typical scenarios of exercises in a sports–day at schools in Japan. The obtained experimental data are then used to construct a model of heart–rate variations, which is then employed for computer simulations to evaluate the effectiveness of the introduced heart–rate transmission control. Our numerical results show that the heart–rate transmission control is effective, especially in a scenario where exercisers with different patterns of heart–rate variations coexist.","PeriodicalId":333786,"journal":{"name":"2017 11th International Symposium on Medical Information and Communication Technology (ISMICT)","volume":"5 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129297990","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 HBC, a high-frequency signal is transmitted by a current flowing through the body surface and via the near-field electric field around it. Due to the lack of specific equipment and tools to measure HBC transmission characteristics, HBC systems are still in the development stage. In this study, a multilayered arm phantom and suitable measurement devices are proposed to measure the transmission efficiency between a 10-MHz transmitter worn on the wrist and a receiver in contact with the palm. Measurements with a real human subject were also performed. Additionally, numerical models for calculating the transmission efficiencies are introduced to validate the measurements. The transmission efficiencies obtained from the measurements using the phantom and from the simulation using the numerical model were in a reasonable agreement; however, the results of the measurements using the phantom and the subject differed, which we attributed to the effect of the body trunk.","PeriodicalId":333786,"journal":{"name":"2017 11th International Symposium on Medical Information and Communication Technology (ISMICT)","volume":"37 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131586234","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}
