This paper focuses on encoding the information in the chemical structure of the messenger molecules so that a complete data frame can be transmitted. Inspired by the frame structure in traditional communication networks, Molecule-as-a-Frame (MaaF) includes a header to allow for frame identifier and destination address bits. The paper shows the existence of a trade-off between the length of the frame identifier and transmit power, and finds the optimal throughput that minimizes the frame error rate.","PeriodicalId":126747,"journal":{"name":"2017 IEEE International Black Sea Conference on Communications and Networking (BlackSeaCom)","volume":"53 2","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"120901376","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 network, the source transmits signals through flat fading channels to a set of intermediate relay nodes which amplify signals and then forwards them to the destination through other flat fading channels. The proposed EE is derived in a balanced scheme with Spectrum Efficiency (SE), when relay location is considered. Such a balance between EE and SE is achieved by minimizing power consumption. Furthermore, the BER for this balance is analyzed and the relationship between BER and EE is derived.

POSIX threads (pthreads) is a low-level bare-bones programming interface for working with threads. Therefore, we have extremely fine-grained control over thread management (create/join/etc), mutexes, and so on. On the other hand, openMP, as a shared-memory standard, is much higher level and portable interface which makes it easier to use multi-threading capability and obtain satisfactory performance improvements. Since pthreads is more flexible, it helps programmers gain more control on performance optimizations. Jerasure 2.0 erasure coding library has encoding/decoding engines which comprise independent “for” loop iterations and hence possess huge potential for multi-threaded processing. In this short paper, we investigate multi-threaded implementations of encoder/decoder pair of Jerasure 2.0 using two different technologies: OpenMP and pthreads. We constrain our changes to a minimum possible and compare the pure encoding/decoding performance with respect to each other as well as against that of the original single-threaded version by running them on two different server systems.","PeriodicalId":126747,"journal":{"name":"2017 IEEE International Black Sea Conference on Communications and Networking (BlackSeaCom)","volume":"28 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133978729","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}

Many studies have been conducted in order to ensure the success of the model on which the IoT has been envisioned. In this study, we devise an architecture under which IoT devices within a certain geographical area can cooperate to achieve some communication goals via exchanging services such as routing and data aggregation, when needed. We use the social relationships among the network objects as the basis for requesting and enabling such services. For this purpose, the architecture allows the definition of several layers of social relations as well as a method for determining these relations and managing them. We then illustrate the practicality of this architecture via simulation experiments and we provide some results based on the experimental scenarios.","PeriodicalId":126747,"journal":{"name":"2017 IEEE International Black Sea Conference on Communications and Networking (BlackSeaCom)","volume":"63 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121355447","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 femtocell power control, the interference experienced by the network is divided into two main tiers according to the type of network whose signal is interfering with another network. In utilizing the functionality of a two-tier network where femtocell technology is deployed, a major challenge is in sharing the frequency resource of a macrocell. This paper proposes an enhanced dynamic algorithm bounded by two constraints to optimize the transmission powers of femtocell users in TDD-OFDM based femtocell networks, taking into consideration rate enhancement of femtocell mobile stations. We compare our algorithm with the macrocell guard system, which allows femtocells to occupy only the subchannels unoccupied by the macrocell.","PeriodicalId":126747,"journal":{"name":"2017 IEEE International Black Sea Conference on Communications and Networking (BlackSeaCom)","volume":"29 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126747497","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}

Therefore, it is crucial to model the number of received molecules until time t. Received signal is modeled analytically when the transmitter is a point and the receiver is an absorbing sphere. Modeling the diffusion-based molecular communication channel with the first-hitting process (i.e., with an absorbing receiver) is an open issue when the transmitter is a reflecting spherical body. In this paper, we utilize the artificial neural networks technique to model the received signal for a spherical transmitter and a perfectly absorbing receiver (i.e., first-hitting process). The proposed technique may be utilized in other studies that assume a spherical transmitter instead of a point transmitter.","PeriodicalId":126747,"journal":{"name":"2017 IEEE International Black Sea Conference on Communications and Networking (BlackSeaCom)","volume":"214 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-11-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115488665","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}
