V2XMiddleware: Publish-Subscribe Data Distribution for Connected Fleets

V2XMiddleware connects raw wireless V2X radio streams with high-level autonomous driving stacks, providing standardized publish-subscribe abstractions, QoS filtering, and zero-copy data routing.

Decoupling Low-Level RF Signals from High-Level Autonomous Planning

Autonomous path planners should not parse raw ASN.1 radio bitstreams. V2XMiddleware transforms incoming CAM, DENM, and CPM packets into strongly-typed internal topics distributed across the vehicle's Ethernet backbone.

Core Engineering Areas

• OMG DDS QoS Profiles — Configuring best-effort versus reliable topic delivery over lossy vehicular communication backbones.
• SOME/IP SOA Integration — Publishing V2X hazard alerts as standardized AUTOSAR services consumable by infotainment and ADAS.
• Zero-Copy Serialization — Direct in-place memory access to incoming vehicle telemetry without memory allocations.
