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…
Performance Optimization of Multiple Interconnected Heterogeneous Sensor Networks via Collaborative Information Sharing
Sougata Pal, Simon Oechsner, Boris Bellalta +1
Interconnecting multiple sensor networks is a relatively new research field which has emerged in the Wireless Sensor Network domain. Wireless Sensor Networks (WSNs) have typically…
