Abstract
In this paper, the problem of socio-physical and mobility-aware coalition formation among the trapped users and the first responders in public safety networks is addressed towards guaranteeing users’ connectivity, stability, and energy-efficient communication. Each user is associated with some socia
Highlights
Public Safety Networks (PSNs) have emerged as the key solution to a successful response to emergency and disaster events, such as acts of terrorism, natural disasters, and technological accidents
Their energy availability, as well as their energy consumption rate are adopted as parameters in the coalition formation process, so as to allow the devices/users with improved energy potential to act as relay/coalition-head for the rest of the users within the coalition, supporting a collaborative and long-lasting communication environment
Though different speeds may be considered, in the following for simplicity and without loss of generality, same speed is assumed for all users and their actual positions at the time slot are determined based on their current position and the moving direction, which in the rest of this paper will be referred as mobility pattern
Summary
Public Safety Networks (PSNs) have emerged as the key solution to a successful response to emergency and disaster events, such as acts of terrorism, natural disasters, and technological accidents. The improved mobile devices’ capabilities raise the demand of sharing multimedia content to facilitate more efficient rescuing operations, broadband communication in PSNs arises more as a requirement rather than as a desire. Towards this direction, the Third Generation Partnership Project (3GPP) has considered the Long-Term Evolution (LTE) to support and facilitate the broadband services in PSNs [3]. The communication infrastructure is often damaged during the occurrence of a disaster event, 3GPP envisions Device-to-Device (D2D) mode of communication as the key driver in emergency situations [4]
