This paper introduces the design, implementation, and performance analysis of the scalable and mobility-aware hybrid protocol named boarder node medium access control (BN-MAC) for wireless sensor networks (WSNs), which leverages the characteristics of scheduled and contention-based MAC protocols. Like contention-based MAC protocols, BN-MAC achieves high channel utilization, network adaptability...

Wireless sensor networks are appealing to researchers due to their wide range of application in several fields such as military settings, critical infrastructure protection, target detection and tracking, environmental monitoring, industrial process monitoring etc. Communication among wireless sensor nodes is usually achieved by means of a unique channel. It is the characteristic of this channe...

Radio Frequency Identification (RFID) has become widespread thanks to its important advantages over traditional identification technologies, like barcodes. Compared to this technology, RFID is, in fact, able to cover larger distance and does not require line-of-sight, that represent important improvements in the considered field of application. An RFID system is formed by a set of n tags, that ...

Traditional MAC protocols used in ad hoc networks employ omnidirectional antennas. Recently, directional antennas have emerged as an alternative due to their capability of spatial reuse, low probability of detection, robustness to jamming, and other beneficial features. In this paper, we conducted a comparison study of existing directional and omnidirectional MAC protocols by contrasting their ...
