Abstract:

This paper introduces three autonomous, criticality-aware packet scheduling policies that address the impact of high traffic loads and degraded conditions in wireless sensor networks. The proposed policies, collectively referred to as Early Packet Drop (EPD), leverage cross-layer information, including RPL Rank, link quality, and time-slotted Medium Access Control schedule, to mitigate Quality of Service degradation. Simulation results demonstrate that EPD consistently outperforms a Criticality-Monotonic Scheduling (CMS) baseline.

I. Introduction

Large-scale machine-to-machine communication plays a key role in enabling the deployment of smart infrastructures in industrial or safety-critical settings. The aggregation and processing of high volumes of data in increasingly complex and dense wireless sensor networks (WSNs) introduces diverse challenges as network devices frequently contend with unpredictable environmental conditions, congestion, and internal interference. Real-time networks may experience surges in traffic during equipment failure, emergency situations or abnormal events prohibiting delivery of all data within stringent deadlines.
