Collision Cb The Extra Match Hot _top_

In high-density communication environments, particularly during unplanned extended events ("extra matches") such as overtime in sports or emergency response, Citizen Band (CB) radio channels become saturated, leading to packet collision, message loss, and system degradation. This paper defines the concept of a Hot Extra Match (HEM) as any sudden, unpredictable surge in channel demand. We analyze collision causes in ALOHA and CSMA-based CB protocols, propose a backoff algorithm adapted from Ethernet's Binary Exponential Backoff, and introduce a "hot standby" frequency hopping mechanism to mitigate interference. Simulation results show a 43% reduction in collision rate during HEM scenarios.

We simulated a CB network of 50 users in a 5 km radius, using a discrete-event model in Python (SimPy). Scenarios: collision cb the extra match hot
