Balasingham","doi":"10.1109/ISABEL.2008.4712576","DOIUrl":"https://doi.org/10.1109/ISABEL.2008.4712576","url":null,"abstract":"The use of biomedical sensor networks in complex clinical diagnostics and treatment may provide greater flexibility for both patient and the medical staff as some of the same sensors could follow the patient throughout the cycle of treatment. Biomedical sensors usually transmit periodically with known intervals and may require medium to higher data rates and lower packet drop rate than most traditional sensor networks. We propose a new method built on the IEEE 802.15.4 standard to enable higher throughput while keeping the packet drop rate at a minimum by utilizing the periodic behavior observed in such sensor networks. The simulation results show that, for certain scenarios, the average throughput compared to the IEEE 802.15.4 standard configuration can be doubled, while keeping the packet drop ratio at a minimum. Furthermore, by utilizing the property of periodic behavior, the channel efficiency has been improved from 30% to 50% compared to the standard IEEE 802.15.4 configuration. We show that the proposed method generates less protocol overhead and significantly reduces the chance of transmission errors due to colliding packets. Thus, it attains operational performance closer to saturation for a given packet discard ratio. Energy consumption due to retransmissions is reduced as the proposed algorithm greatly reduces collisions and requires few retransmissions. The proposed method requires minimum computational complexity and can be used on sensor nodes in a decentralized manner.","PeriodicalId":435116,"journal":{"name":"2008 First International Symposium on Applied Sciences on Biomedical and Communication Technologies","volume":"59 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-12-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126869686","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}

We consider the classical problem of the multi-source impulse discharge separation from intramuscular EMG signals in the case where the impulse responses (motor unit action potentials, MUAPs) are supposed to be known to a certain degree. The main contribution of this work is the proposal of a fully unsupervised EMG decomposition algorithm that exploits both the signal model likelihood and the regularity of the motor unit discharge patterns in a Bayesian framework. The latter, though well-proven properties in the past, is essentially used as auxiliary information in an interactive procedure [1] involving human interventions. Another contribution consists of using the Tabu metaheuristics to solve the NP-hard problem over the complete search space of overlapped MUAP, unlike the existing methods that either performed on the restrained search spaces [2, 3] due to complexity or based on recursive algorithms [4, 1] with certain trial strategy and residual threshold estimations.","PeriodicalId":435116,"journal":{"name":"2008 First International Symposium on Applied Sciences on Biomedical and Communication Technologies","volume":"53 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-12-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131840244","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}
