Due to the mobility feature of use terminals in the real environment, the analysis of successful transmission is particular important in mobile networks. In this paper, the position of cache-enabled users are distributed as a Homogeneous Poisson Point Process (HPPP) and user moves following the random walk mobility (RWM) model. Then, the successful transmission probability is analyzed through the observation of the one step movement of the typical user using stochastic geometry methods. Meanwhile, in order to optimize the successful transmission probability, two methods are considered, i.e., file segmentation transmission (FST) and retransmission mechanism (RM). Simulation results show that the successful transmission probability can be improved by several network parameters, e.g., user density, transmission zone radius and caching probability, but exhibits a decline with increasing velocity or downloading time. Besides, considering segmentation cost, there is a tradeoff for the optimal segment number for the FST and RM schemes.","PeriodicalId":6656,"journal":{"name":"2017 IEEE International Conference on Communications Workshops (ICC Workshops)","volume":"26 1","pages":"1382-1387"},"PeriodicalIF":0.0,"publicationDate":"2017-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"84687051","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}

Most of the existing works mainly focus on a deterministic setting where the scheduling problem can be solved using various congestion management approaches. In this paper, we develop a stochastic solar generation model and a performance index (the Figure of Merit) to measure the charging station's utility as well as EVs' charging requirements, taking account of the effect of solar energy prediction errors. We further propose a two-stage process (first admission control and then charging scheduling) to find the best solution to the EV charging problem. The results show that the proposed two-stage admission and scheduling mechanism outperforms the First In First Out (FIFO) scheme in terms of reducing delay time and increasing revenue, so that the charging station performs better. The proposed mechanism can also adapt well to uncertain solar generation by finding the optimal trade-off between accepting EVs and missing charging deadlines.","PeriodicalId":6656,"journal":{"name":"2017 IEEE International Conference on Communications Workshops (ICC Workshops)","volume":"8 1","pages":"1304-1309"},"PeriodicalIF":0.0,"publicationDate":"2017-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"90671059","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}

When all user data is sent to each BS through the CP, which is referred as the full cooperation, the interference can be perfectly eliminated, however, this may cause the capacity of backhaul links to be exceeded. In this study, it is aimed to find the optimal asymmetric cooperation strategy for downlink cloud radio access network (C-RAN) which minimizes the total transmitted power from BSs where each user's signal-to-interference-and-noise ratio (SINR) is lower bounded and the number of user data streams sent by each BS is limited. The original problem is NP-hard and requires a combinatorial search. In this paper, we propose two sub-optimal cooperation methods. The first method is based on iteratively increasing the number of users served by the BSs until all users are chosen, and the second is based on iteratively adding a user data stream to be sent to a BS. We also consider a known method, iterative link removal, which is based on iteratively removing a user data from a BS by starting the full cooperation scheme, and a modified version of this method as a comparison. The simulation results show that the proposed methods can provide better performance in comparison to other methods in the literature.","PeriodicalId":6656,"journal":{"name":"2017 IEEE International Conference on Communications Workshops (ICC Workshops)","volume":"11 1","pages":"132-137"},"PeriodicalIF":0.0,"publicationDate":"2017-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"89759352","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 recently developed concept coded random access is capable of resolving collisions in massive access at MAC layer. Furthermore, Compressive Sensing Multi-User Detection (CS-MUD) achieves joint activity and data detection from the PHY layer perspective by exploiting sparsity in sporadic multi-user detection. In [1], a joint design of these two concepts was semi-analytically evaluated combining CS-MUD with coded random access under certain assumptions, which showed a promising performance for supporting MMC. In this work, a full link-level analysis of the joint protocol will be presented to verify the previous results and provide deep insights on the link-level performance. Although the joint approach on the link-level shows a small throughput loss compared to the semi-analytical evaluation, high system flexibility can be achieved by tuning MAC and PHY resources dynamically based on the numerical analysis which can be referred to in the joint MAC-/PHY-layer design.","PeriodicalId":6656,"journal":{"name":"2017 IEEE International Conference on Communications Workshops (ICC Workshops)","volume":"24 1","pages":"1018-1023"},"PeriodicalIF":0.0,"publicationDate":"2017-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"79446195","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 standard presents Time Slotted Channel Hopping (TSCH) Medium Access Control (MAC) protocol, which provides high reliability and low power consumption to various industrial applications. Despite the effectiveness and the importance of the TSCH protocol, the standard leaves out of its scope in defining how the schedule is built and maintained. In this work, we focus on scheduling in IEEE 802.15.4-2015 TSCH networks from the energy efficiency perspective in a centralized manner where the gateway makes frequency allocations and time slot assignments. At first, we derive an energy consumption model of a TSCH node to determine the network lifetime. Afterwards, we formulate the scheduling problem as an energy efficiency maximization problem, which is a nonlinear integer programming. Motivated by the high computational complexity of the problem, we propose a low-complexity Energy Efficient Scheduler (EES) and Vogel's Approximation Method Heuristic Scheduling Algorithm (VAM-HSA). We make a comparison with the Round Robin Scheduler (RRS) and analyse the schedulers in terms of success probability and energy efficiency. Performance evaluation indicates that EES and VAM-HSA perform better in terms of energy efficiency, while at the same time yielding a good throughput.","PeriodicalId":6656,"journal":{"name":"2017 IEEE International Conference on Communications Workshops (ICC Workshops)","volume":"28 1","pages":"570-575"},"PeriodicalIF":0.0,"publicationDate":"2017-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"84111607","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}
