An Energy-Efficient MAC protocol for Wireless Sensor Network

摘要：

It is widely known that in wireless sensor networks (WSN), energy efficiency is of utmost importance. WSN need to be energy efficient but also need to provide better performance, particularly latency. A common protocol design guideline has been to trade off some performance metrics such as throughput and delay for energy. This paper presents a novel MAC (Express Energy Efficient Media Access Control) protocol that not only preserves the energy efficiency of current alternatives but also coordinates the transfer of packets from source to destination in such a way that latency and jitter are improved considerably. Our simulations show how EX-MAC (Express Energy Efficient MAC) outperforms the well-known S-MAC protocols in several performance metrics.
