Multipath transmission control protocol (MPTCP) exploits the multihoming feature of mobile terminals to implement concurrent multipath transfer over heterogeneous wireless networks. In this paper, we propose a delay-based congestion control algorithm (DBCCA) for MPTCP to optimise the transmission performance. The proposed algorithm mainly includes two steps. First, a constrained optimization problem is formed to minimize the delay difference of different paths and a near-optimal rate distribution vector is obtained with genetic algorithm. Second, we adjust the congestion windows based on the acquired rate distribution vector and the round-trip time to distribute traffic over each path. Jointly considering the throughput and the delay, DBCCA effectively optimizes mobile traffic transmission in heterogeneous networking environment. Experimental results show that DBCCA shifts part of traffic from the higher loss paths to the lower ones, which significantly improves throughput.","PeriodicalId":121352,"journal":{"name":"2019 IEEE Wireless Communications and Networking Conference Workshop (WCNCW)","volume":"39 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133109936","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 present experimental results of outdoor measurements under line of sight (LoS) conditions showing 4-by-8 multiple-input multiple-output (MIMO) throughput performance when applying distributed MIMO with narrow antenna beam tracking in a 28-GHz frequency band in the downlink of a 5G cellular radio access system. To clarify a suitable deployment for a MS traveling along a straight line, two deployment cases are tested in which three BSs are used. One is a case where all transmission points (TPs) are arranged along the moving path of the MS, and the other is a case where two of the three TPs are on each side of the moving path. The experiments, in which the MS is installed on an electric trolley, reveal that the former deployment case has a trade-off relationship between the peak throughput and range. This relationship yields a higher peak throughput for a decrease in the TP separation distance. In contrast, the latter deployment case achieves both a high peak data rate and better throughput performance over the entirety of the traveling path compared to the former case, and exhibits the peak throughput value of 15 Gbps, which is almost the system peak value.","PeriodicalId":121352,"journal":{"name":"2019 IEEE Wireless Communications and Networking Conference Workshop (WCNCW)","volume":"252 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122718822","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}

Particularly, vehicle-to-vehicle( V2V) communication has attracted extensive research both in academy and industry, which is believed to have great potential to reduce traffic congestion and accidents. V2V communication has stringent requirements on latency and access availability. In this paper, we study the joint admission control and resource allocation problem in V2V networks with the objective to maximize the number of concurrent V2V transmissions, where we classify vehicles users as safety V-UEs and non-safety V-UEs. Firstly, we construct the conflict graph based on the interference relations of vehicles. And then we model the problem as a graph coloring problem(GCP), which is an NP-complete problem. Finally, a resource sharing and admission control(RSAC) algorithm is proposed to solve this problem. Simulation results shows that the proposed algorithm outperforms the existing scheme in terms of both throughput and capacity performance.","PeriodicalId":121352,"journal":{"name":"2019 IEEE Wireless Communications and Networking Conference Workshop (WCNCW)","volume":"27 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126259031","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 analyze an energy-efficient (EE) power allocation problem for opportunistic user under feasibility constraints. When the SU is allowed to transmit with an OFDM technique, these constraints guarantee: a minimum SU’s Quality of Service (QoS) level, a maximum average transmit power and the protection of the PUs by maximum average interference levels at the PUs receivers. In this paper, we study a relevant EE metric which is the weighted difference between overall achievable rate and power consumption. It is difficult to solve this EE power allocation problem via optimization tools since the opposing character of the constraints. Thus, we propose a novel method based on a flowchart algorithm. We have shown that our proposed power allocation solution outperforms the classical water-filling solution and the sub-optimal one.

To make full use of mmWave access, deploying ultra-broadband backhauling lines such as optical fibers everywhere is an extremely expensive approach. mmWave meshed network is therefore a cost-efficient wireless backhaul architecture for mmWave overlay cellular network. Owing to its wide bandwidth and flexibility in link connection via beam steering and multi-hop relay, mmWave meshed network is furthermore suitable for dynamic construction of backhauling in adaptation to change of user traffic’s distribution via adaptive allocation of backhaul resources of densely co-located users (UE). On the other hand, as users nowadays want to experience services everywhere without disruption even when moving, it is desirable that UE-specific multimedia contents are located as close as possible to the UE via Mobile Edge Computing (MEC) technology. Covering all the above requirements, this paper aims to construct a real UE-centric edge content delivery system in which content server is re-located in adaptation to UE’s context information e.g. location, via dynamic routing over mmWave meshed backhaul network, enabled by Software Defined Network (SDN) technology. Using our developed WiGig device based testbed, outdoor experiment campaign is conducted in the university campus with various measurement scenarios. This paper describes the overall testbed architecture and the conducted outdoor experiment with preliminary results revealing the effectiveness of the proposed system.","PeriodicalId":121352,"journal":{"name":"2019 IEEE Wireless Communications and Networking Conference Workshop (WCNCW)","volume":"109 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121992375","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}

To deal with the problem, we introduce an embeddable convolutional layer-based filter (Conv-based filter), which takes raw time domain signal as input and can adaptively learn characteristics of the band-pass filter whose center frequency and bandwidth are compatible with the target signal. To enhance the performance of learned filters, the attention mechanism is introduced by using Squeeze-and-Excitation block (SE-block) after Conv-based filters. As an embeddable block, the filter is trained end-to-end in a deep learning network, no explicit assumptions about the raw data are made.

This permission, which is a part of the 5G specifications, is due to the scarcity of the licensed spectrum and the increased use of wireless networks and services. However, these unlicensed bands are mainly occupied by 802.11 based WLAN devices. Thus, challenges arise for the efficient coexistence mechanism to share the same unlicensed band by LAA and Wi-Fi to maintain the quality of service and manage the interference among users. In this work, we propose new variable contention window (CW) methods for LAA to enable the coexistence of LTE and Wi-Fi in a fair manner based on the Wi-Fi statistics. The main novelty of this work is that the knowledge of Wi-Fi activity statistics is exploited to adapt the CW of LAA more effectively. These methods are evaluated based on the 3GPP fairness definition for such coexistence mechanisms under various traffic loads. We show that the fairness depends on the LAA CW size. Further, through simulation results, we show that the proposed schemes are more friendly to the existing Wi-Fi network, in particular for the higher traffic loads, compared with the existing Category 4 Listen-Before-Talk (Cat 4 LBT) algorithm defined in the 3GPP standard and provide higher total throughputs for both coexisting networks, improving the overall network performance.","PeriodicalId":121352,"journal":{"name":"2019 IEEE Wireless Communications and Networking Conference Workshop (WCNCW)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128817846","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}
