Adaptive Resource Allocation Scheme for TETRA Networks With Multi-Operators
In this paper, the authors evaluate various aspects of packet data transmission in TErrestrial Trunked RAdio (TETRA) networks giving particular emphasis on the performance of applications transmitting data between a number of radio terminals and a fixed server. The utilization of such applications is constantly increasing in public safety networks and so does the need to dimension and configure TETRA networks to meet their reliability, delay and loss requirements. Without an efficient Radio Resource Management (RRM), one operator can exhaust the capacity of others. This paper tackles an efficient scheduling to provide maximum system throughput and proportional fairness in accordance with operator capacity share through adaptive resource allocation scheme.
