Success Prioritized Binary Exponential Backoff Algorithm for Non-Persistent CSMA
Umehara Daisuke, Jinhong Yuan · 2019
We present a success prioritized binary exponential backoff algorithm of non-persistent carrier-sense multiple access (NP-CSMA) for vast-area large-scale data gathering with power-limited wireless sensors in order to simultaneously gain the transmission and energy efficiencies of the wireless communication devices in this paper. The proposed medium access control (MAC) mechanism does not require any additional physical-layer functions such as multiple antennas, interference canceller, etc. It has high flexibility and scalability without any complex configuration in an autonomous and distributed manner. In this paper, we provide a performance analysis model to estimate the throughput and consumed energy for the proposed backoff algorithm. We show the validity of the performance analysis model by comparing the analysis results with the simulation results for the number of active nodes more than 500 of interest to us.
