A Distributed Method for Evaluating Properties of a Robot Formation
As a robot formation increases in size or explores places where it is difficult for a human operator to interact, autonomous control becomes critical. We propose a distributed aut...

Performance Evaluation of Joint FEC and ARQ Optimization Heuristic Algorithms under Gilbert-Elliot Wireless Channel
— In this paper, we evaluate the performance of adaptive algorithms for selecting the number of redundant packets by jointly considering the forward error correction (FEC) and au...
