Broadcast Range Performances for Random Access-Based Wireless Mutual Broadcast

The wireless mutual broadcast (WMB) sharing informative data among proximal nodes has been recently spotlighted as a key enabler for smarter and safer society. These WMB applications may require different intended broadcast coverage (BC) depending on their attributes, and this coverage is profoundly affected by mutual interference among nodes. In this regard, this letter investigates the BC in terms of the proximity between nodes [so called the broadcast range (BR)] under a stochastic geometry framework. Furthermore, it proposes the design principles to improve the performances for an intended BR.
