An Energy-Efficient Clustering and Routing Framework for Disaster Relief Network

open access: yesIEEE Access, 2019
The lack of communication between local authorities, first aid responders, and the population that are present in a natural disaster area, represents critical aspects which can compromise relief operations in saving human lives. During natural disasters (

Interference constrained device-to-device communications [PDF]

open access: yes2014 IEEE International Conference on Communications (ICC), 2014
This paper considers a scenario in which multiple device-to-device (D2D) users can reuse the uplink resources of a cellular network to transmit directly to their corresponding receivers. The aggregated interference from the D2D users is limited by applying a threshold on the allowable interference in the base station.
