Motivated by its potential applications, we tackle in this paper the task assignment problem for a requester encountering a crowd of participants while considering their mobility model and sensing preferences. We aim to minimize the overall processing time of sensing tasks. Hence, we introduce first the Mobility-Aware Task Assignment scheme in both oFfline (MATAF) and oNline (MATAN) models where requesters investigate the participants' arrival model in different compounds of the sensing region. Further, we enhance such schemes by jointly taking into account participants' mobility and sensing preferences. We advocate then two other task assignment models, P-MATAF (offline) and P-MATAN (online). All proposed algorithms adopt a greedy-based selection strategy and address the minimization of the average makespan of all sensing tasks. We conduct extensive performance evaluation based on real traces while varying the number of tasks and associated workloads. Results proved that our proposed schemes have achieved lower average makespan and higher number of delegated tasks.","PeriodicalId":158785,"journal":{"name":"Proceedings of the 19th ACM International Conference on Modeling, Analysis and Simulation of Wireless and Mobile Systems","volume":"16 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-11-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124062262","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}

State-of-the-art network selection strategies distribute data traffic to available networks, but ignore an important second dimension: time. Time selection offers the opportunity to plan usage of future-available networks for delay-tolerant data traffic. We hypothesize, that concurrent selection of network and time leads to synergy effects, which reduce transmission cost and boost connectivity performance. To assess data distribution to wireless networks and time, we propose a novel rating model for joint network and time selection. The proposed model rates the satisfaction of Quality-of-Service (QoS) application requirements and trades off conflicting optimization goals. Moreover, we analyze the impact of time in network selection and present three network selection schedulers, which differ in their time selection strategy. Evaluation of the results reveals a strong impact of time selection on network performance. This gives evidence, that our initial hypothesis holds and forward-looking scheduling strategies provide a substantial benefit over state-of-the-art approaches.","PeriodicalId":158785,"journal":{"name":"Proceedings of the 19th ACM International Conference on Modeling, Analysis and Simulation of Wireless and Mobile Systems","volume":"13 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-11-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134095028","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}

One of the candidate wireless technologies for these wireless sensor networks is the IEEE 802.15.4 standard which operates in the 2.4 GHz ISM band. This is while the number of wireless devices that operate in this band is ever increasing. This broad usage of the same RF band may cause considerable performance degradation of wireless networks due to interference. There is some work on the coexistence of the IEEE 802.15.4 protocol and other standard technologies such as IEEE 802.11 (Wi-Fi) and IEEE 802.15.1 (Bluetooth), but none of it considers the highly dynamic conditions of in-vehicle networks. In this paper, we investigate the interference behavior in in-vehicle environments using real-world experiments. We consider different scenarios and measure the interference on all the 16 channels of IEEE 802.15.4 in the 2.4 GHz band.The measurement data set is available to the public. This real-world data set can be used for realistic and accurate network simulation. To study the effect of interference on in-vehicle networks, we use this data set to evaluate the performance of an IEEE 802.15.4e TSCH link. The simulation results show that the packet error rate for some interference scenarios is considerably high and dynamic over time. This shows the value of the data set and reveals the importance of using adaptive interference mitigation techniques to improve the reliability of wireless in-vehicle networks.","PeriodicalId":158785,"journal":{"name":"Proceedings of the 19th ACM International Conference on Modeling, Analysis and Simulation of Wireless and Mobile Systems","volume":"21 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-11-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116282986","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}

Whilst densification could lead to increased coverage (neighbouring APs belonging to the same administrative domain), which is good news, it could also lead to increased interference (neighbouring APs not belonging to the same administrative domain). In particular, in the latter case, nodes (both APs and STAs) in neighbouring networks could carrier sense each other and resist from transmitting when in fact a parallel transmission could have been harmless. Thus, improving spatial reuse in such scenarios is crucial to improving performance in dense deployments otherwise the efficiency is likely to take a hit. This paper elaborates on dynamic sensitivity control (DSC), a way of adapting the carrier sensing threshold dynamically to address the aforementioned issue and presents results from a simulation based study aimed at evaluating the proposed method. Findings indicate that the gains achievable from deploying DSC vary significantly depending on the operating conditions and therefore, choosing a fixed conservative threshold at design time, as has been the case traditionally, may not be an appropriate decision. We also show that enabling DSC at the AP may bring benefits with the performance approaching that of the traditional method (of not adapting sensitivity) in the conservative case.","PeriodicalId":158785,"journal":{"name":"Proceedings of the 19th ACM International Conference on Modeling, Analysis and Simulation of Wireless and Mobile Systems","volume":"82 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-11-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127117529","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}
