Research On Power Efficient Radio Resource Allocation Strategy Based Integrated Air-ground Networks

With the rapid development of broadband mobile communication, how to use the limited network resources to meet the growing needs of users is a challenging ploblem that the manufacturers and mobile operators need to solve. The third generation of partner organizations (3GPP) started the long term evolution (LTE) to provide greater capacity, higher throughput and better quality of service (QoS). However, the existing system architecture and network protocol may not satisfy all kinds of service requirements in emergency scenarios. It will cause network paralysis or even interruption once the fixed infrastructure is damaged or there is a shortage of power supply. Hence, it is necessary to design an emergency network which can get compatible with regular ones for fighting against disasters.This paper will mainly research on radio resource allocation problems for integrated air-ground communication system. The conclusion will be achieved by using both the mathematical theory analysis and computer simulation. In this paper, firstly, the concept of emergency communication and its unsolved problems are proposed to determine the research area and purpose. Seconly, considering the progress made by related study, our research approach is divided into two parts, which can be defined as hardware and software. On one hand, the system architecture of integrated air-ground communication is set up to solve the problem of damaged infrastructure. On the other hand, based on cooperative game theory, a power efficient radio resource allocation algorithm is proposed to solve the problem of short of power supply. Finally, we will compare our algorithm with other classic algorithms. The simulation results demonstrate that the proposed algorithm inposes an attractive tradeoff between the achievable throughput and the power consumption while ensuring fairness among users.
