Resource Allocation in Device to Device Communication using Dynamic Programming

Device to device communication is an emerging technology and considered as a significant part of fifth generation wireless networks. It provides better communication in terms of improvement in system throughput and resource utility with shortened communication delay. Even though device to device communication improves energy and spectral efficiency by skipping the direct connection through base station, it suffers with some technical challenges. This paper summarizes the implementation challenges of spectrum allocation, and mainly focuses on resource allocation and spectrum sharing using dynamic programming approach. In addition, both single and priority based queuing models are employed to satisfy the user request. Finally, performance of the proposed approach is compared with greedy, brute force, successive and fractional approaches.
