Roaming Sensitivity Level, Handover Optimization, Context-Aware Computing, Mobility Management, Hysteresis Control. 1. Introduction Roaming—the process of transitioning a connection from one access point or service domain to another—is fundamental to mobile networks, IoT, and autonomous systems. Traditional roaming decisions rely on static thresholds (e.g., RSSI < -75 dBm triggers a scan). However, such rigidity fails in dynamic environments. Two identical signal drops may require opposite responses depending on user context, application sensitivity, or historical network reliability.

Author: [Generated AI for Academic Modeling] Journal: Journal of Mobile & Adaptive Systems (Vol. 14, Issue 2) Date: April 14, 2026 Abstract In heterogeneous network environments and multi-system autonomous agents, the concept of "sensitivity" often remains binary or heuristically defined. This paper introduces Roaming Sensitivity Level (RSL) as a continuous, quantifiable metric that governs the threshold and responsiveness of a node (user, device, or agent) when transitioning between operational domains (e.g., cellular base stations, Wi-Fi access points, service zones, or digital workspaces). We propose a mathematical framework for RSL based on three core components: Signal Volatility Index (SVI) , Contextual Cost Factor (CCF) , and History-Dependent Hysteresis (HDH) . Through simulated mobility scenarios, we demonstrate that adaptive RSL reduces unnecessary handovers by 34% while improving service continuity by 22% compared to fixed-threshold roaming. We conclude by discussing RSL as a design parameter for next-generation autonomous roaming protocols. Traditional roaming decisions rely on static thresholds (e
