摘要：Wireless Sensor Networks (WSNs) become more and more important in emerging new applications as message delivery timeliness is highly concerned. However, supporting reliability, real-time and Quality of Service in sensor networks have faced many challenges due to their wireless nature, limited resource, dynamic network topology, and the demand of distributed architecture.Reliable data delivery in real time (latency aware) and Energy efficiency are the two most important parameters for designing protocol. Hence, reliable data delivery in real time is required to ensure that a packet reaches its desired destination in actual time and energysaving mechanisms are required for battery constrained sensor networks.The aim of the paper is to study the latency aware and energy efficient Medium Access Control (MAC) protocolsfor wireless sensor network andto motivate the researcher, while showing the future aspects in the area of Wireless Sensor Networks.
