A Survey on Real-Time MAC Protocols in Wireless Sensor Networks

Abstract: As wireless sensor network becomes pervasive, new requirements have been continuously emerged. However, the most of research efforts in wireless sensor network are focused on energy problem since the nodes are usually battery-powered. Among these requirements, real-time communication is one of the big research challenges in wireless sensor networks because most of query messages carry time information. To meet this requirement, recently several real-time medium access control protocols have been proposed for w… Show more

“…Many researchers shifted their research attention to this application. Accordingly, works on reviewing MAC protocol investigated this objective such as [19]- [22]. The sampling rate and the density of multimedia sensor as parameters on multimedia data, for example, were analysed in depth with the relation of energy efficiency.…”

“…The design of Bluetooth requires all nodes within its piconet to be synchronized within a few microseconds. This requirement cannot be met by many wireless sensor networks as they have large network latencies due to several constraints within them [26]. With typical Bluetooth configuration, it would take around 2.4 microseconds to establish a connection.…”

“…The other major issue confronting the communication in wireless sensor networks in large latencies from source to destination [26]. Higher latencies in communication path is the result of low bandwidth connections, network congestion, multi-hop communication and processing in intermediate nodes.…”

“…Moreover, three comprehensive survey literatures 2 Wireless Communications and Mobile Computing for real-time routing [7][8][9] were published to provide the comparison in the aspects of energy efficiency and reliability. Teng and Kim [10] addressed the specific requirement of realtime MAC protocol in WSN by surveying recent wireless sensor real-time MAC protocols. However, mentioned research work focuses on network or MAC protocol, respectively, and does not provide any classification principle.…”
