Gathering despite a linear number of weakly Byzantine agents
Jion Hirose, Junya Nakamura, Fukuhito Ooshita +1
We study the gathering problem to make multiple agents initially scattered in arbitrary networks gather at a single node. There exist agents with unique identifiers (IDs) in th…
Network Bandwidth Variation-Adapted State Transfer for Geo-Replicated State Machines and its Application to Dynamic Replica Replacement
Tairi Chiba, Ren Ohmura, Junya Nakamura
This paper proposes a new state transfer method for geographic state machine replication (SMR) that dynamically allocates the state to be transferred among replicas according to ch…
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…
Evacuation from Various Types of Finite 2D Square Grid Fields by a Metamorphic Robotic System
Junya Nakamura, Sayaka Kamei, Yukiko Yamauchi
A metamorphic robotic system (MRS) is composed of anonymous, memoryless, and autonomous modules that execute an identical distributed algorithm to move while keeping the connectivi…
