The communication between the devices are enabled and controlled through Machine Type Communications (MTC). MTC has a wide range of applications and forms an integral part of IoT. The 3rd Generation Partnership Project (3GPP) standardization body has recognized the potential for MTC and is currently working on standardizing the specifications and deployment of MTC services as part of Long Term Evolution (LTE) networks. The system requirements of these MTC devices are different from the regular devices using the LTE network. Many MTC devices are expected to be low cost, low data rate and delay tolerant. One of the challenges in MTC using 3GPP LTE is to reduce the power consumption of the User Equipment (UE) in order to prolong their battery life. The power consumption of a UE is directly proportional to its processing time. In this paper, we introduce quick sleeping to the current 3GPP LTE MTC framework. First, we compare the quick sleeping mechanism with the present Discontinuous Reception (DRX) mechanism for sleeping in LTE and show that there can be significant savings in the UE processing time if quick sleeping is adopted. Then we present different methods to incorporate quick sleeping into the Physical Broadcast Channel (PBCH) with minimal changes to the current LTE standard. The impact of these quick sleeping solutions on PBCH Block Error Rate (BLER) performance is also discussed.","PeriodicalId":354340,"journal":{"name":"2014 IEEE Globecom Workshops (GC Wkshps)","volume":"11 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"117087321","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 scheme is based on cell division, migration and death dedicated to exploiting the sleep mode of base stations to reduce the number of active base stations in a SCN for energy saving. Direction Of Arrival is used in a distributed way to adapt networks to the dynamic traffic conditions. Simulation results show that the proposed scheme saves 39% power at low traffic loads compared with no topology management. With the scheme, SCNs can react to various traffic loads and consequently can sustain at least 1.2 Gbps/km2/MHz traffic with low blocking probability. The proposed scheme is compared to an existing topology management scheme and demonstrated to attain similar performance while reducing information exchange overhead. The alternative configurations of the scheme are investigated and analyzed.","PeriodicalId":354340,"journal":{"name":"2014 IEEE Globecom Workshops (GC Wkshps)","volume":"21 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128319223","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}

Under the same quality of service constraints, we find the optimal network density that minimizes the area power density. Our results show that the existence of an optimal BS density for minimizing the power consumption depends on the value of the pathloss exponent.","PeriodicalId":354340,"journal":{"name":"2014 IEEE Globecom Workshops (GC Wkshps)","volume":"60 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128605715","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}

However, as the evolution of wireless systems moves towards shorter distance transmission and smaller cell sizes, the computational energy in wireless hardware becomes significant alongside transmit radio energy. In this paper, we develop energy models for a point-to-point wireless transmission that consider practical aspects such as multipath fading, error-control coding and receiver synchronization. The total energy consumption of the wireless system is modeled as a function of modulation scheme, data rate, signal bandwidth, code rate, received signal-to-noise ratio (SNR) and channel parameters. We choose a multipath Rayleigh-fading channel model and Reed-Solomon coding scheme for the numerical analyses. Simulation results show that there exists an optimal parameter configuration that gives the minimum energy consumption for given data and bit-error rates. At short transmission distances, computational energy dominates and higher-order modulation schemes with low bandwidth allocation are shown to be more energy efficient.","PeriodicalId":354340,"journal":{"name":"2014 IEEE Globecom Workshops (GC Wkshps)","volume":"26 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130523726","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}

Within our research, we focus on a typical application of multiple cloud enabled small cells located within a local area network, typically in company premises. The user offloading request is processed by small cells according to their current availability of resources. However, the user equipment does not need to be directly associated with it. Therefore, the transmitted data need to be secured by a different mechanism that ensures end-to-end security and identity of each communicating party in order to prevent various attacks. For that purpose, we propose a hierarchical structure of certificate authorities which is an asymmetric cryptographic scheme based on modified X.509 digital certificates. Beside the previously stated issues, the proposed scheme also decreases computing time needed for certificate validation as well as validation delay introduced by the online certificate status protocol and limits the necessity of communication with the main certificate authority.","PeriodicalId":354340,"journal":{"name":"2014 IEEE Globecom Workshops (GC Wkshps)","volume":"36 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129077857","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}

CCN names packets rather than end-hosts, and most of CCN's characteristics are the consequences of this fact. However, the current design of CCN has some limitations in traffic control, especially in flow fairness and node-to-node collaboration. To solve this problem, we propose an SDN-based autonomie system as the control plane to supplement CCN traffic management. Correspondingly, in the data plane, we utilize a multiprotocol switch to support CCN protocol, flow-aware content delivery and traffic control. We also discuss the implementation and extension issues, and finally, we demonstrate our hybrid scheme to perform centralized and intelligent traffic management, which provides higher awareness, fairness, and low congestion.","PeriodicalId":354340,"journal":{"name":"2014 IEEE Globecom Workshops (GC Wkshps)","volume":"67 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121646842","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}

Coverage analysis and system performance is performed for a small cell system at 60GHz. Peak throughputs beyond 3Gbps and cell edge throughputs in excess of 500Mbps are demonstrated at 98% of the mobile test locations. Analogue codebook based beamforming is applied. The analysis of the statistical angular spread at the mobiles is shown to be clustered; leading to many users selecting the similar analogue beamforming code which results is high levels of co-channel interference. It is often assumed that the use of analogue beamforming implies a single beam pattern pointing in a specific direction to support a single user. In this case users that cannot be spatially separated must be scheduled in different time slots. However, due to the clustered aspect of the users' angle spreads, those with the same beam code can still be scheduled in the same time slot using different frequency channels via a single RF chain. The paper analyses a scheduling scheme based on this concept. The same scheduling scheme is applied to systems operating at 28, 38 and 60GHz where different numbers of frequency channels are available. Different user densities and street scenarios are studied. The 60GHz scheme make use of 4 frequency channels and is shown to double the system throughput compared to operation at 28GHz band using a single frequency channel. Finally, the optimal number of RF chains required at the base station is analysed. This is shown to be a critical design issue for mmWave cellular systems.","PeriodicalId":354340,"journal":{"name":"2014 IEEE Globecom Workshops (GC Wkshps)","volume":"95 ","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"113993044","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}

On account of predicted invading numbers of M2M devices, with restricted data needs, the resulting network signaling load poses a great challenge to cellular operators. Data aggregation is an attractive approach to deal with this situation; each aggregator node collects measurements from a group of M2M devices over a capillary network and relays the aggregated data over the cellular access network. In this paper, we conduct a detailed experimental study using state-of-the-art drive testing equipment in order to capture and analyze the impact of M2M data aggregation on signaling overhead in cellular networks with focus on static M2M devices such as smart meters and monitoring sensors.
