Open Wireless Architecture (OWA) Enabled Shared Mobile Community Networks

1. Introduction

1.1 Background and Motivation

The rapid expansion of wireless technologies has led to a fragmented landscape where multiple standards coexist! Wi-Fi, Bluetooth, Zigbee, LTE, and 5G. Community networks aim to leverage this diversity by providing shared access to broadband services, but face challenges in interoperability, spectrum management, and security. Open Wireless Architecture (OWA) addresses these challenges by abstracting radio technologies and enabling virtualization, multi-mode access, and intelligent resource management.

4. Protocol Stack and Quality of Service

4.1 OWA_Visitor Network Protocol (OVNP)

The OWA_Visitor Network Protocol (OVNP) is a core protocol designed to enable seamless, secure, and quality-driven connectivity for visitor mobile terminals (MTs) within shared mobile community networks. OVNP operates at the convergence of Layer 2 and Layer 3! [often termed Layer 2.5!] to provide advanced handover management, resource allocation, and quality-of-service (QoS) enforcement across heterogeneous wireless environments.

4.1.1 Protocol Architecture and Layer 2.5 Functionality

OVNP is architected to bridge the gap between traditional data link (Layer 2) and network (Layer 3) layers, enabling intelligent decision-making and coordination that is not possible with standard protocols.

Layer 2.5 Handover Mechanism:

* Context Awareness: OVNP maintains real-time context about ongoing sessions, including application state, security credentials, and network conditions.

* Seamless Transition: When a visitor MT moves between OWA_Visitor Routers, OVNP orchestrates the handover process, minimizing service interruption.

* QoW-Based Triggering: Handovers are initiated based on dynamic Quality of Wireless (QoW) metrics, including throughput, latency, jitter, and packet loss, ensuring uninterrupted user experience.

4.1.2 Key Protocol Components

OVNP Control Plane:

* Session Management: Establishes, maintains, and terminates visitor sessions.

* Handover Coordination: Communicates with neighboring OWA_Visitor Routers to prepare for and execute handovers.

* QoW Monitoring: Continuously collects and analyzes QoW metrics from the wireless link and application layers.

OVNP Data Plane:

* Packet Forwarding: Routes data packets between the visitor MT and the network, ensuring low latency and high reliability.

* Packet Prioritization: Implements QoS policies to prioritize critical traffic (e.g., voice, video) based on application requirements and network conditions.

4.1.3 Protocol Operation and Message Types

4.1.4 Handover Process

QoW Monitoring:

* The MT continuously monitors QoW metrics (every 500 ms).

* If QoW drops below predefined thresholds, the MT sends a QoW Report to the current OWA_Visitor Router.

Handover Decision:

* The router evaluates the QoW Report and scans for neighboring routers with better signal quality.

* If a suitable target is found, the router initiates a Handover Request to the target router.

Context Transfer:

* The current router transfers session context (security keys, application state) to the target router.

Handover Execution:

* The MT disconnects from the current router and connects to the target router.

* The target router sends a Handover Response to confirm successful transition.

Session Continuity:

* The MT resumes its session with minimal interruption, leveraging context preservation.

4.1.5 Quality of Wireless (QoW) Management

QoW Metrics Collection:

* Throughput: Measured in real-time to ensure sufficient bandwidth.

* Latency: Monitored to maintain interactive application performance.

* Jitter: Tracked to prevent audio/video distortion.

* Packet Loss: Measured to ensure reliable data delivery.

Adaptive Algorithms:

* OVNP employs adaptive algorithms to dynamically adjust handover thresholds and resource allocation based on network conditions and application needs.

4.1.6 Security and Authentication

Secure Context Transfer:

* Session context, including security keys and application state, is encrypted during transfer.

* Mutual authentication between the MT and routers ensures only authorized devices participate in handovers.

Credential Management:

* Visitor credentials are securely provisioned and revoked by the VMS, preventing unauthorized access.

4.1.7 Integration with OWA Virtualization Layer

OVNP is tightly integrated with the OWA Virtualization Layer, leveraging Open Interface Parameters (OIP) for standardized communication and resource management3.?This integration enables OVNP to operate across diverse radio transmission technologies (RTTs), ensuring consistent performance and interoperability.

4.1.8 Advantages and Innovations

* Seamless Roaming: Enables visitor MTs to roam among multiple OWA_Visitor networks with minimal service disruption.

* QoW-Driven Handover: Ensures optimal user experience by prioritizing network transitions based on real-time quality metrics.

* Cross-Technology Compatibility: Operates across WLAN, WPAN, BWA, and cellular networks, thanks to OWA!/s virtualization and abstraction layers3.

* Enhanced Security: Implements robust authentication and encrypted context transfer to protect user data and privacy.

Summary of said OVNP:

OVNP is a sophisticated protocol that enables intelligent, secure, and quality-driven connectivity for visitor mobile terminals in shared mobile community networks. By operating at Layer 2.5, OVNP provides advanced handover management, QoW-based resource allocation, and seamless integration with the OWA virtualization framework, ensuring a superior user experience across heterogeneous wireless environments
