📐 Key Calculations

Mesh Hop Count

log₂(N_nodes)
Result: ≤4 hops
Ensured latency <1s for alarm delivery

Battery Life Estimate

Capacity / (I_avg × t_cycle)
Result: 8.2 years
Exceeded 5-year maintenance window requirement

📊 Results

Reduced installation cost by 63%; achieved 99.992% data availability; enabled real-time inventory reconciliation and leak detection
