A real-time and energy-efficient MAC protocol for wireless sensor networks

摘要: Energy saving has been the primal issue in designing medium access control (MAC) protocols for wireless sensor networks (WSNs). However, with advent of new micro electro-mechanical systems (MEMS) technologies and recently thermo-powered solar-powered nodes – where operate virtually an unlimited time period research community is set to experience many diverse directions this area. Factors like timeliness, scalability, synchronisation, adaptivity reliability will play their part near future. This paper discusses AREA-MAC, a MAC protocol specially designed real-time energy-efficient WSN applications. AREA-MAC reduces latency energy consumption by using low power listening (LPL) technique short preamble messages. Other B-MAC use long messages that cause higher latency, overhead. Moreover, provides reasonable trade-offs between vital parameters such as system fairness, throughp...
