Communication-Efficient Self-stabilization in Wireless Networks

A self-stabilizing protocol is guaranteed to eventually reach a safe (or legitimate) configuration even when started from an arbitrary configuration. Most of self-stabilizing protocols require each process to keep communicating with all of its neighbors forever even after reaching a safe configuration. Such permanent communication impairs efficiency, but is necessary in nature of self-stabilization.
The concept of communication-efficiency was introduced to reduce communication after reaching a safe configuration. The previous concept targets the point-to-point communication model, and is not appropriate to the wireless network model where a process can locally broadcast a message to its neighbors all at once.
In this paper, we refine the concept of the communication-efficiency for the wireless network model, and investigate its possibility in self-stabilization for some fundamental problems; the minimal (connected) dominating set problem, the maximal independent set problem, and the spanning tree construction problem.
