Bogdan S. Chlebus, Vicent Cholvi, Dariusz R. Kowalski

TL;DR
This paper introduces a new model for stability in multi-hop wireless networks considering routing, scheduling, and hearing control, and analyzes the stability of various policies under different conditions.
Contribution
It extends the adversarial queueing framework to multi-hop radio networks, defining universal stability and analyzing the stability of known policies under new hearing control mechanisms.
Findings
Proves unstable policies in wireline remain unstable in radio networks.
Shows SIS and LIS are stable with proactive hearing control.
LIS can be stabilized with tie-breaking, SIS cannot.
Abstract
In this article we introduce a new model to study stability in multi-hop wireless networks in the framework of adversarial queueing. In such a model, a routing protocol consists of three components: a transmission policy, a scheduling policy to select the packet to transmit form a set of packets parked at a node, and a hearing control mechanism to coordinate transmissions with scheduling. For such a setting, we propose a definition of universal stability that takes into account not only the scheduling policies (as in the standard wireline adversarial model), but also the transmission policies. First, we show that any scheduling policy that is unstable in the classical wireline adversarial model remains unstable in the multi-hop radio network model, even in scenarios free of inter- ferences. Then, we show that both SIS and LIS (two well-known universally stable scheduling policies in the…
