This paper presents a simultaneous localization and mapping (SLAM) algorithm that allows a recursive state estimation process to be both distributed and decentralized in a sparse robot network that is never guaranteed to be fully connected (communication-wise). In such a sparse network, a robot may not always have the latest odometry and measurements from other robots. Our approach allows robots to...
Communication among robots is key to performance in cooperative multi-robot systems. In practice, communication connections for information exchange between all robots are not always guaranteed, which adds difficulty to state estimation. This paper examines the decentralized cooperative simultaneous localization and mapping (SLAM) problem under a sparsely-communicating and dynamic network. We mathematically...
Finite-range sensing and communication are factors in the connectivity of a dynamic mobile robot network. State estimation becomes a difficult problem when communication connections for information exchange between all robots are not guaranteed. This paper presents a decentralized state estimation algorithm guaranteed to work in dynamic networks without connectivity requirements. We show that a robot...
Performance of a Concurrency Control Algorithm (CCA) managing a distributed database system will deteriorate considerably when the configuration of the network supporting it will change due to either communication link failures or the communication delays introduced by varying load patterns. To get a good performance in spite of the changing configurations, we propose a scheme that involves breaking...
