This technique not only preserves data privacy of edge devices but also simultaneously ensures high learning performance. However, the emerging federated edge learning still confronts serious challenges, such as the lack of efficient training task assignment schemes with reliable edge devices acting as workers. To address this challenge, we utilize a many-to-one matching model to solve the training task assignment problem between the workers and multiple task publishers. In the matching model, we minimize not only the overall training time of the task publishers but also the energy consumption of the workers. To define against malicious model updates from unreliable workers, we present reputation as a metric to evaluate the reliability and trustworthiness of the edge devices, and also take the reputation into consideration when assigning training tasks. The numerical results indicate that the proposed schemes can efficiently improve the performance of federated edge learning.","PeriodicalId":443862,"journal":{"name":"2020 IEEE 17th Annual Consumer Communications & Networking Conference (CCNC)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130134174","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}

Surveillance of highways with the use of a helicopter is a costly option that could be replaced with a more economical option of UAVs. Unlike MANETs in general and VANETs in particular, UAV networks have unique characteristics due to the association of factors like dynamic topology, high mobility, and limited energy. Keeping in view the real-time aspect of road surveillance, the use of UAVs with the existing routing protocols is not a straight forward option. A fleet of drones en route to surveillance on the highways may face frequent link failures due to its dynamical sparse linear architecture. To compensate for the sparse topology, a collaboration of UAVs with VANETs might be a good choice but as such integration of the two networks could create too much overhead. In this article, a proactive energy-efficient and reliable Collaborative scheme between UAVs and VANETs, termed as CUV, is presented. To avoid flooding in the entire network, Base station Association Messages (BAM), in a unicast manner, are forwarded till the end-nodes. Although BAM is received by each node which ensures connectivity with the BS but only certain nodes are allowed to retransmit. Furthermore, to take care of the loss of BAM messages due to the presence of hidden nodes, a novel mechanism for link repair inside a BAM interval is introduced. The proposed scheme is simulated in Network-Simulator-2 and compared with the well known proactive OLSR and reactive AODV protocols.","PeriodicalId":443862,"journal":{"name":"2020 IEEE 17th Annual Consumer Communications & Networking Conference (CCNC)","volume":"80 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121164240","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}

Furthermore, they confirmed dynamic channel selection in a local area where devices are crowded. In this paper, we conduct evaluation experimentation in real environment where devices are coexisting with other IoT systems, Sigfox and LoRaWAN.

We focus on exploiting the source routing capability of SR to enhance the performance of IP fast reroute. In particular, an IP router detects a local link failure, it can immediately reroute the affected packets by tunneling them to a SR router. The SR router will then forward the rerouted packets along a SR path such that when they exit the SR domain, they can reach the destination without traversing the failed link. In order to maximize the percentage of links that can be protected by fast reroute, two Integer Linear Programming (ILP) formulations are proposed for finding optimal repair paths for rerouted packets. ILP1 aims at minimizing the repair path length and ILP2 focuses on balancing the traffic load in the network. We further show that as the number of SR routers increases, the average repair path length will be shortened and the load balancing performance will be improved.","PeriodicalId":443862,"journal":{"name":"2020 IEEE 17th Annual Consumer Communications & Networking Conference (CCNC)","volume":"15 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130432313","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}

By modifying wireless properties such as transmission timeslots or frequencies, the wireless links quality can be optimized in order to reach optimal communication at the network level. In this paper, we approach the wireless network optimization problem as a distributed constraint optimization problem. As an inherently distributed task, the number of constraints, variables, and their domain sizes can be very large. Therefore, incomplete and local-search solutions such as the Distributed Stochastic Algorithm (DSA) are best suited to solve this class of problems. In this work, we study the wireless network optimization procedure of such solvers considering wireless messaging cost. Furthermore, we introduce Weighted-DSA a stochastic algorithm for wireless optimization. By reducing the search-space of the variables and re-exploring periodically, results show that this algorithm is able to reach optimal solution quality under minimal messgeing costs.","PeriodicalId":443862,"journal":{"name":"2020 IEEE 17th Annual Consumer Communications & Networking Conference (CCNC)","volume":"27 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134235140","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}

A solution obtained from pre-designed objective functions cannot always be the best channel set due to external factors in the wireless environment. It is difficult to take into account external factors in advance, so we propose to allocate channels based on several performance metrics that can only be measured by operating access points. The fine-tuning during actual operation involves a trade-off between exploration and exploitation for the best channel set. In addition, we should utilize a channel set that performs not so good on some metrics but well on other metrics. By using MOMAB, we can balance between exploration and exploitation of Pareto optimal channel sets for multiple metrics. The experimental results demonstrate that the proposed method successfully identifies a Pareto optimal channel set.","PeriodicalId":443862,"journal":{"name":"2020 IEEE 17th Annual Consumer Communications & Networking Conference (CCNC)","volume":"22 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134645040","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}

The coordinated sampled listening (CSL) is one of the IEEE 802.15.4e-based low-power media access control (MAC) protocols, and it is a candidate protocol for the RLMM systems. To construct the CSL-based RLMM systems in a variable environment, the communication characteristics should be evaluated theoretically and experimentally. In this paper, we designed a practical CSL protocol for the implementation, and a theoretical analysis scheme to evaluate communication characteristics of the practical CSL is proposed considering with the effect of Acknowledgement (ACK) frames. Furthermore, the practical CSL protocol is demonstrated experimentally using 30 actual Wi-SUN dongles in a radio anechoic chamber. The proposed theoretical analysis results agree well with not only computer simulation results but also experimental results.
