Localization Procedure for Randomly Deployed Wireless Sensor Networks
Luis Sanabria-Russo, Cristina Cano, Boris Bellalta
Wireless Sensor Networks (WSNs) are composed of nodes that gather metrics like temperature, pollution or pressure from events generated by external entities. Localization in WSNs i…
Modelling a Decentralized Constraint Satisfaction Solver for Collision-Free Channel Access
Jaume Barcelo, Nuria Garcia, Azadeh Faridi +2
In this paper, the problem of assigning channel slots to a number of contending stations is modeled as a Constraint Satisfaction Problem (CSP). A learning MAC protocol that uses de…
Spectrum Sensing with USRP-E110
Luis Sanabria-Russo, Jaume Barcelo, Albert Domingo +1
Spectrum sensing is one of the key topics towards the implementation of future wireless services like SuperWiFi. This new wireless proposal aims at using the freed spectrum resulti…
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…
