Dynamic Clustering and ON/OFF Strategies for Wireless Small Cell Networks
Sumudu Samarakoon, Mehdi Bennis, Walid Saad +1
In this paper, a novel cluster-based approach for maximizing the energy efficiency of wireless small cell networks is proposed. A dynamic mechanism is proposed to group locally-cou…
Enhanced Transmit Antenna Selection Scheme for Secure Throughput Maximization Without CSI at the Transmitter and its Applications on Smart Grids
Hirley Alves, Mauricio Tomé, Pedro H. J. Nardelli +2
This paper addresses the establishment of secure communication links between smart-meters (Alice) and an aggregator (Bob) in the presence of an eavesdropper (Eve). The proposed sce…
Average Error Probability in Wireless Sensor Networks with Imperfect Sensing and Communication for Different Decision Rules
Pedro H. J. Nardelli, Iran Ramezanipour, Hirley Alves +2
This paper presents a framework to evaluate the probability that a decision error event occurs in wireless sensor networks, including sensing and communication errors. We consider…
Contention-based Geographic Forwarding Strategies for Wireless Sensors Networks
Carlos H. M. de Lima, Pedro H. J. Nardelli, Hirley Alves +1
This paper studies combined relay selection and opportunistic geographic routing strategies for autonomous wireless sensor networks where transmissions occur over multiple hops. Th…
Effects of Relay Selection Strategies on the Spectral Efficiency of Wireless Systems with Half- and Full-duplex Nodes
Carlos H. M. de Lima, Hirley Alves, Pedro. H. J. Nardelli +1
This work proposes an analytical framework to study how relay selection strategies perform in half- and full-duplex deployments by combining renewal theory and stochastic geometry.…
Modeling and Analysis of Content Caching in Wireless Small Cell Networks
Syed Tamoor-ul-Hassan, Mehdi Bennis, Pedro H. J. Nardelli +1
Network densification with small cell base stations is a promising solution to satisfy future data traffic demands. However, increasing small cell base station density alone does n…
Maximizing the Link Throughput between Smart-meters and Aggregators as Secondary Users under Power and Outage Constraints
Pedro H. J. Nardelli, Mauricio de Castro Tomé, Hirley Alves +2
This paper assesses the communication link from smart meters to aggregators as (unlicensed) secondary users that transmit their data over the (licensed) primary uplink channel. The…
Throughput Maximization in Multi-Hop Wireless Networks under Secrecy Constraint
Pedro H. J. Nardelli, Hirley Alves, Carlos H. M. de Lima +1
This paper analyzes the throughput of industrial communication networks under a secrecy constraint. The proposed scenario is composed by sensors that measure some relevant informat…
Co-Primary Multi-Operator Resource Sharing for Small Cell Networks
Petri Luoto, Pekka Pirinen, Mehdi Bennis +3
To tackle the challenge of providing higher data rates within limited spectral resources we consider the case of multiple operators sharing a common pool of radio resources. Four a…
