A QoS Monitor Selection Mechanism for Cellular Data Networks

This paper presents a novel distributed Quality of Service (QoS) monitoring scheme for cellular data networks serving highly dynamic users with power- limited devices. The proposed scheme relies on candidate QoS monitoring users that can efficiently submit QoS related measurements on behalf of their neighbors. These candidate users are chosen according to their devices´ residual power and transmission capabilities and their estimated remaining service lifetime. Service monitoring users are then selected from these candidates using a novel user-to-user semantic similarity matching algorithm. Simulation results demonstrate the significant gains achieved by the proposed scheme in terms of the reduced traffic overhead and overall consumed users´ devices power while achieving a high monitoring accuracy.
