Energy-Efficient and Delay-Aware MAC Protocol in Wireless Sensor Networks for Oil and Gas Pipeline Monitoring
Huaping Yu, Mei Guo · 2015
A flexible and energy efficient media access control (MAC) protocol is the fundament of wireless sensor networks for oil and gas pipeline systems.This paper firstly analyses the typical MAC protocols, three layers architecture of WSNs, and then proposes energy efficient and delay aware MAC (EEDA-MAC) protocol for oil and gas pipeline monitoring.Secondly, two frame structures of EEDA-MAC protocol for long line structure are introduced, and some improvement strategies for EEDA-MAC protocol are proposed and discussed such as energy consumption balance strategies, preambles mechanisms, adaptive and asynchronous competition mechanisms, ladder scheduling mechanisms, which can effectively prolong the network life span and improve the network delay performance.
