Evaluation and Ranking of Replica Deployments in Geographic State Machine Replication
Shota Numakura, Junya Nakamura, Ren Ohmura
Geographic state machine replication (SMR) is a replication method in which replicas of a service are located on multiple continents to improve the fault tolerance of a general ser…
A State Transfer Method That Adapts to Network Bandwidth Variations in Geographic State Machine Replication
Tairi Chiba, Ren Ohmura, Junya Nakamura
We present a new state transfer method for geographic State Machine Replication (SMR) that dynamically allocates the state to be transferred among replicas according to changes in…
A cooperative partial snapshot algorithm for checkpoint-rollback recovery of large-scale and dynamic distributed systems and experimental evaluations
Junya Nakamura, Yonghwan Kim, Yoshiaki Katayama +1
A distributed system consisting of a huge number of computational entities is prone to faults, because faults in a few nodes cause the entire system to fail. Consequently, fault to…
Gathering of seven autonomous mobile robots on triangular grids
Masahiro Shibata, Masaki Ohyabu, Yuichi Sudo +3
In this paper, we consider the gathering problem of seven autonomous mobile robots on triangular grids. The gathering problem requires that, starting from any connected initial con…
