Medium Access Control (MAC) protocols of Wireless Sensor Network (WSN) are often required to have special characteristics in concrete applications. Related and Urgent message should be sent First (RUF) is a typical scenario in many applications of WSN. In this paper, we focus on presenting a MAC protocol for RUF applications in WSN. First of all, through analysis, some concrete cases of RUF sce...

SUMMARY The development of new MAC protocols to deal with emerging applications for infrastructure-free networks, such as wireless sensor networks, is currently impeded by the lack of a common benchmarking standard to determine the suitability of certain protocols to certain scenarios. There is a need to rectify this situation to facilitate the development of new MAC protocols by improving the ...

Extensive researches on Wireless Sensor Networks (WSNs) have been performed and many techniques have been developed for the data link (MAC) layer. Most of them assume single-channel MAC protocols. In the usual dense deployment of the sensor networks, single-channel MAC protocols may be deficient because of radio collisions and limited bandwidth. Hence, using multiple channels can significantly ...

Efficient MAC protocol has been paramount importance for improving the performance of WSN. In this paper, Boarder Node Medium Access Control (BN-MAC) mobility aware hybrid protocol is introduced for WSN. BNMAC controls overhearing, idle listening and congestion problem to save energy. BN-MAC mechanism is based on novel semi synchronous low duty cycle that takes less time for accessing channel a...
