TDMA-based scheduling for multi-hop wireless sensor networks with 3-egress gateway linear topology

Linh Vu Nguyen, Nguyen Viet Ha, Masahiro Shibata +1

Packet transmission scheduling on multi-hop wireless sensor networks with 3-egress gateway linear topology is studied. Each node generates a data packet in every one cycle period a…

Self-Stabilizing Construction of a Minimal Weakly -Reachable Directed Acyclic Graph

Junya Nakamura, Masahiro Shibata, Yuichi Sudo +1

We propose a self-stabilizing algorithm to construct a minimal weakly -reachable directed acyclic graph (DAG), which is suited for routing messages on wireless networ…

The Power of Global Knowledge on Self-stabilizing Population Protocols

Yuichi Sudo, Masahiro Shibata, Junya Nakamura +2

In the population protocol model, many problems cannot be solved in a self-stabilizing way. However, global knowledge, such as the number of nodes in a network, sometimes allows us…
