Cloudlets Activation Scheme for Scalable Mobile Edge Computing with Transmission Power Control and Virtual Machine Migration
TL;DR: This paper proposes an algorithm that utilizes Virtual Machine Migration and Transmission Power Control, together with a mathematical model of delay in Mobile Edge Computing and a heuristic algorithm called Particle Swarm Optimization, to balance the workload between cloudlets and consequently maximize cost-effectiveness.
Journal ArticleDOI
Interference-Aware Channel Segregation Based Dynamic Channel Assignment for Wireless Networks
TL;DR: It is shown that the IACSDCA can form a CCI-minimized channel reuse pattern in a distributed manner and that it improves the signal-to-interference ratio (SIR) compared to the other channel assignment schemes.
Proceedings ArticleDOI
Computationally efficient 2-step QRM-MLD for single-carrier transmissions
TL;DR: This paper proposes a computationally efficient 2-step QRM-MLD SC-FDBD that can significantly improve the bit error rate (BER) performance of SC transmission while reducing significantly the computational complexity compared to the MLD.

Kiyohiko Hattori,Naoki Tatebe,Toshinori Kagawa,Yasunori Owada,Lin Shan,Katsuhiro Temma,Kiyoshi Hamaguchi,Keiki Takadama +7 more
TL;DR: The results of the performed experiments showed that the proposed method outperformed the conventional method with regard to the deployment time, power consumption, and the distances traveled by the robots, andThe movement function along the walls is effective while passing a narrow corridor unlike any other function.
Proceedings ArticleDOI
Linearly distributed antenna diversity using single frequency network for high-speed railway communications
Jimmy Hadi Susanto,Hiroyuki Miyazaki,Katsuhiro Temma,Tetsuya Yamamoto,Tatsunori Obara,Fumiyuki Adachi +5 more
TL;DR: In this paper, frequency-domain space-time block coded-joint transmit/receive diversity (FD-STBC-JTRD) is employed as SFN linearly distributed antenna diversity and it is confirmed by computer simulation that FD- STBC- JTRD is a powerful diversity to improve the transmission performance under a high mobility environment.
