The integration of slotted Aloha with power domain non-orthogonal multiple access (NOMA), dubbed slotted Aloha-NOMA (SAN) can emerge as an appealing MAC protocol to be used for Internet-of-Things (IoT) applications over 5G networks. In this paper, SAN is discussed, and its performance is evaluated in detail. The simulation results demonstrate that the maximum normalized throughput can be increased from 0.37, which is the case for slotted Aloha, to 1 by means of SAN. Specifically, this full throughput efficiency can be obtained at all low, medium and high network traffics. Besides that, the average delay can be significantly reduced compared to the slotted Aloha.

A Framework for Energy based Performability models for Wireless Sensor Networks
Omondi, Fredrick A.; Shah, Purav; Gemikonakli, Orhan; Ever, Enver (2015-03-27)
A novel idea of alternating node operations between Active and Sleep modes in Wireless Sensor Network (WSN) has successfully been used to save node power consumption. The idea which started off as a simple implementation of a timer in most protocols has been improved over the years to dynamically change with traffic conditions and the nature of application area. Recently, use of a second low power radio transceiver to triggered Active/Sleep modes has also been made. Active/Sleep operation modes have also be...
ALOHA-NOMA for Massive Machine-to-Machine IoT Communication
Balevi, Eren; Rabee, Faeik T. Al; Gitlin, Richard D. (2018-07-27)
© 2018 IEEE.This paper proposes a new medium access control (MAC) protocol for Internet of Things (IoT) applications incorporating pure ALOHA with power domain non-orthogonal multiple access (NOMA) in which the number of transmitters are not known as a priori information and estimated with multihypothesis testing. The proposed protocol referred to as ALOHA-NOMA is not only scalable, energy efficient and matched to the low complexity requirements of IoT devices, but it also significantly increases the throug...
An Efficient Constrained mm-Wave Hybrid Massive MIMO Beamforming for JSDM based NOMA
Bayraktar, Murat; Güvensen, Gökhan Muzaffer (2021-06-01)
Massive MIMO and non-orthogonal multiple access (NOMA) are key technologies for next generation wireless systems due to their distinct advantages. We previously proposed a general framework on unification of code-domain NOMA and joint spatial division and multiplexing (JSDM) which is a spatial user-grouping based hybrid beamforming method for massive MIMO. In this paper, we propose a constrained analog beam-former design for JSDM based systems. Moreover, we propose joint group processing for the digital bea...
An Information security framework for web services in enterprise networks
Sarıkoz, Bahadır Gökhan; Günel Kılıç, Banu; Department of Information Systems (2015)
Web Service, an open standard based on existing Internet protocols, provides a flexible solution to web application integration. It provides faster, more practical and more effective way of solutions for the organizational structures. Online shopping, billing, reservation and other way of standards provided to people mostly depend on web services. On the other hand, it provides corporate identity and functionality of an organization. Since the importance and the necessity of the web services increase day by...
A Greedy Link Scheduler for Wireless Networks With Gaussian Multiple-Access and Broadcast Channels
Sridharan, Arun; Koksal, C. Emre; Uysal, Elif (Institute of Electrical and Electronics Engineers (IEEE), 2012-02-01)
Information-theoretic broadcast channels (BCs) and multiple-access channels (MACs) enable a single node to transmit data simultaneously to multiple nodes, and multiple nodes to transmit data simultaneously to a single node, respectively. In this paper, we address the problem of link scheduling in multihop wireless networks containing nodes with BC and MAC capabilities. We first propose an interference model that extends protocol interference models, originally designed for point-to-point channels, to includ...
