Cooperative Relay Selection and Power Allocation Optimization in Emergency Communication System
摘要
Abstract
In order to improve channel capacity and energy efficiency in emergency communication system, a cooperative relay selection and power allocation for joint optimization algorithm is presented. In the dynamic communications environment, it improves communication system channel capacity by selecting the best hope of collaboration in relay set. To minimize user and the whole network energy consumption, through the use of convex optimization methods, a reasonable distribution of the source node and a reasonable number of relay nodes between reasonable transmission power are done. Theoretical analysis and simulation experiments show that the proposed algorithm with lower complexity significantly improves the system's channel capacity and energy efficiency.关键词
