Physical mobility is one of the most important challenges for them. Common wireless technologies and protocols, e.g., WirelessHART and ISA100.11a Wireless for industrial process plants, ZigBee for building automation, or 6LoWPAN and 6TiSCH in context of the IoT, are based on the IEEE 802.15.4 standard. Event-based simulation is the method of choice for analyzing network protocols and algorithmic applications of such distributed sensor applications. Performance measurements and holistic evaluations, however, are greatly influenced by the underlying hardware resources, physical layer protocols, and radio channel conditions, which are usually not considered or highly abstracted in network simulations. In this paper we present SEmulate, a hybrid system for seamless (network) simulation and hardware-based emulation for wireless sensor networks based on the IEEE 802.15.4 protocol standard, which takes the hardware aspects into account by applying an Hardware-in-the-Loop (HIL) approach.","PeriodicalId":185451,"journal":{"name":"2019 15th Annual Conference on Wireless On-demand Network Systems and Services (WONS)","volume":"20 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116853492","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}

Frequency reuse is employed to maximize capacity gains. However one major challenge is introducing the fundamental problem of interference management in the network caused by the sharing of the spectrum among the different tiers of the HetNet. Power control (PC) is one technique for interference management which can also be used to enhance the overall system efficiency. The objective of this paper is to study the problem of cross-tier interference management for underlay D2D users in a heterogeneous macro-small cell network assuming imperfect Channel State Information (CSI). The network consists of one macro-cell with a centered MBS and one small-cell cellular user equipment (SUE) linked to its SCBS. Fractional programming (FP) is used to solve the optimization problem of power allocation in the network to find the optimal power that maximizes the sum rate of D2D and small cellular users while guaranteeing a minimum quality of service (QoS) of the macro cellular user.","PeriodicalId":185451,"journal":{"name":"2019 15th Annual Conference on Wireless On-demand Network Systems and Services (WONS)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130122296","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 mobile sensor networks, the resource-constrained move-assisted sensor nodes are used in an area to maximise the coverage within a reasonable time and energy cost. Recently, a family of algorithms, inspired by the equilibrium of molecules, have been proposed to address the coverage issue. However, these solutions lead to high energy cost and latency due to two major issues. First, almost all the nodes in the network try to move to a new position at each stage. Even worse, the decision made at each node on to which point to move at each stage is purely based on obsolete information, i.e. the current locations of moving neighbouring nodes. In this paper, we propose a new distributed algorithm, called SSND, to efficiently provide the maximum coverage for WSNs that use mobile nodes. SSND avoids to collectively, and blindly, move sensor nodes at each step but to apply an eligibility function to elect a few nodes to move using the valid information to obtain the maximum effect. Our extensive simulation study under various operational conditions shows not only a higher percentage of area coverage by SSND but with much lower power consumption and latency than those of the other protocols recently reported in the literature.","PeriodicalId":185451,"journal":{"name":"2019 15th Annual Conference on Wireless On-demand Network Systems and Services (WONS)","volume":"13 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128910648","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}

Reliable data communication is the key to such applications, besides better and smarter local sensors (e.g., radar or video). Current platooning solutions primarily build upon vehicular networking technologies such as Dedicated Short Range Communication (DSRC) and cellular V2X. However, high communication reliability is still a concern, particularly with high vehicle densities due to increasing interference levels. In order to alleviate this, the use of Visible Light Communication (VLC) instead of, or in addition to Radio Frequency (RF), has been proposed. We explore the capabilities of RF and VLC based communication protocols for platooning with a strong focus on reliability. Additionally, we propose and explore heterogeneous solutions using RF and VLC together complementing each other. By means of extensive simulations, we analyze the performance of all these solutions. Based on realistic simulation models, we show that significant improvements in terms of reliability can be achieved by integrating VLC. In this initial study, we also show that deeply integrated heterogeneous communication with RF and VLC can bring platooning one step closer to large-scale real-world deployment.","PeriodicalId":185451,"journal":{"name":"2019 15th Annual Conference on Wireless On-demand Network Systems and Services (WONS)","volume":"33 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":"124223315","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 such heterogeneous networks, mobile terminals (MTs) experience frequent handovers causing high control overhead and link failure probability. To reduce control overhead and to ensure seamless mobility, logical separation between control plane and data plane has been evolved as a promising solution. In control/user-plane (C/U) split network architecture, macro-cell base stations provide control coverage using a low frequency band signal, whereas small cells provide high data rate transmissions to the MTs over high frequency band signals. While performing handovers over small cell base stations, throughput perceived by an MT may fall below the requested data rate. To improve the user perceived throughput at cell edges, recently dual connectivity (DC) has been proposed for long term evolution (LTE) cellular networks. However, analyzing the performance of DC in C/U split LTE heterogeneous networks is quite limited in the preceding literature. In this work, we analyze the performance of DC in C/U plane split network architecture explicitly considering data rate demands of the MTs, traffic arrival pattern, channel conditions as well as target call dropping probability. Our analyses reveal that the performance gain of DC over traditional hard handover is actually conditional on traffic load density in small cell base stations.","PeriodicalId":185451,"journal":{"name":"2019 15th Annual Conference on Wireless On-demand Network Systems and Services (WONS)","volume":"2013 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":"133033734","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 this paper, we present a Multi-access Edge Computing (MEC)-based VRU safety system as an alternative to earlier purely ad-hoc communication-based ones, in which VRU smartphones utilize the cellular connection to frequently send context messages to a MEC server. However, in such safety systems, calculating context information on smartphones, which are already resource-restricted, could lead to reduced battery lifetime and, thus, to poor user experiences. To deal with this issue, we propose an adaptive approach for VRU context information calculation, which considers the use of computation offloading when needed in order to save energy while still ensuring timeliness. As a baseline, we use our machine learning application for determining pedestrian activities. Both experimental and simulation results suggest that it is worth to offload context information computation to the MEC when the updating interval or the sensor sampling frequency is low, i.e., the amount of raw data collected is small; otherwise, local execution is preferable. We see our results as a basis for designing more energy-efficiency calculation models for VRU safety systems.","PeriodicalId":185451,"journal":{"name":"2019 15th Annual Conference on Wireless On-demand Network Systems and Services (WONS)","volume":"549 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":"128861144","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}
