Bottom-up Broadband Initiatives in the Commons for Europe Project
Jaume Barcelo, Boris Bellalta, Roger Baig +5
This paper offers an overview of the Commons for Europe (C4EU) project and the role of Bottom-up Broadband (BuB) in developing the information society. BuB is characterized by the…
Performance Analysis of CSMA/CA Protocols with Multi-packet Transmission
Boris Bellalta, Azadeh Faridi, Dirk Staehle +3
Wireless objects equipped with multiple antennas are able to simultaneously transmit multiple packets by exploiting the channel's spatial dimensions. In this paper, we study the be…
Performance Analysis of a Multiuser Multi-Packet Transmission System for WLANs in Non-Saturation Conditions
Boris Bellalta, Azadeh Faridi, Jaume Barcelo +2
Multiuser Multi-Packet Transmission (MPT) from an Access Point (AP) equipped with multiple antennas to multiple single-antenna nodes can be achieved by exploiting the spatial dimen…
On the Distributed Construction of a Collision-Free Schedule in Multi-Hop Packet Radio Networks
Jaume Barcelo, Boris Bellalta, Cristina Cano +2
This paper introduces a protocol that distributively constructs a collision-free schedule for multi-hop packet radio networks in the presence of hidden terminals. As a preliminary…
Hierarchical Range Sectoring and Bidirectional Link Quality Estimation for On-demand Collections in WSNs
Víctor Valls, José Luis Sánchez, Cristina Cano +2
The paper presents two mechanisms for designing an on-demand, reliable and efficient collection protocol for Wireless Sensor Networks. The former is the Bidirectional Link Quality…
On the Performance of Packet Aggregation in IEEE 802.11ac MU-MIMO WLANs
Boris Bellalta, Jaume Barcelo, Dirk Staehle +2
Multi-user spatial multiplexing combined with packet aggregation can significantly increase the performance of Wireless Local Area Networks (WLANs). In this letter, we present and…
