Various MAC (Medium Access Control) protocols with different objectives have been proposed for WBANs. The fact that any flaw in these critical systems may lead to the loss of one's life implies that testing and verifying MAC's protocols for such systems are on the higher level of importance. In this paper, we firstly propose a high-level formal and scalable model with timing aspects for a MAC protocol particularly designed for WBANs, named S-TDMA (Statistical frame based TDMA protocol). The protocol uses TDMA (Time Division Multiple Access) bus arbitration, which requires temporal aspect modeling. Secondly, we propose a formal validation of several relevant properties such as deadlock freedom, fairness and mutual exclusion of this protocol at a high level of abstraction. The protocol was modeled using a composition of timed automata components, and verification was performed using a real-time model checker.","PeriodicalId":348452,"journal":{"name":"International Conferences on Internet of Things, Embedded Systems and Communications","volume":"27 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129205865","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 achieve this end, three-particle swarm optimization (PSO) based algorithms were applied: Multi-Objective Particle Swarm Optimizer (OMOPSO), Speed-constrained Multi-Objective PSO (SMPSO) and Dual Multi-Objective PSO (DMOPSO). Firstly, the machine design is transformed to a multi-objective constrained optimization problem. Ten design variables were selected to be optimized and two objective functions were used: the machine mass minimization and its efficiency maximization. Secondly, the three PSO-based techniques were applied and the optimization results are presented and discussed.","PeriodicalId":348452,"journal":{"name":"International Conferences on Internet of Things, Embedded Systems and Communications","volume":"18 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116885914","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}
