Hidden Terminal-Aware Contention Resolution With an Optimal Distribution
Achieving low-power operation in wireless sensor networks with high data load or bursty traffic is challenging. The hidden terminal problem is aggravated with increased amounts of data in which traditional backoff-based contention resolution mechanisms fail or induce high latency and energy costs. The authors analyze and optimize Strawman, a receiver-initiated contention resolution mechanism that copes with hidden terminals. They propose new techniques to boost the performance of Strawman while keeping the resolution overhead small. They finally validate their improved mechanism via experiments.
