The SISCOM (Smart Services for Information Systems and Communication Networks) research group focuses on technologies that make it possible to provide intelligent services for information services and communication networks. More specifically, the interests of the group are mainly focused on two areas:

1. Communication networks: We work mostly on wireless networks, either with infrastructure or adhoc and mesh. With the aim of improving their performance, telematics engineering techniques are used. Also, routing protocols are designed and evaluated to guarantee the quality of service required to support intelligent services.

2. Security and privacy of the information: We work on the development of information protection techniques, especially on anonymization of databases to protect users' privacy when these data are being analysed by third parties. These techniques allow us to protect communications and personal information in data analysis processes.



Application examples: Anonymization of medical databases, protection of user privacy in Web browsing, electronic voting, communication in wireless networks without infrastructure (vehicle adhoc networks, mesh networks, mobile adhoc networks), design of efficient routing protocols for wireless infrastructureless networks, personal networks.

Social impact: Health sector, administration, electric operators, telecommunications service operators, smart city services, electrical vehicle, autonomous vehicle.
