The most prominent standard in low-power radio technology is IEEE 802.15.4. It defines both the PHY layer (e.g., the modulation scheme used) and the MAC layer (e.g., in a network, which mote talks when, on which channel). The first revision of the standard was published in 2003, with revisions in 2006 and 2011. Several working
The IEEE802.15.4e standard was published in 2012 as an amendment to the Medium Access Control (MAC) protocol defined by the IEEE802.15.4-2011 standard. The Timeslotted Channel Hopping (TSCH) mode of IEEE802.15.4e is the object of this page. TSCH was designed to “allow IEEE802.15.4 devices to support a wide range of industrial applications”. At its core is
The Internet is composed of many networks, a number of which are typically traversed by a packet on its way from source to destination. Thus, for each type of link layer technology which the network is based on, there needs to be an “IP-over-X” specification that defines how to transport IP packets. In many cases, to map the
Wireless sensor networks (WSNs) find wide applications in environmental monitoring. MAC protocolsplay a vital role in controlling the energy consumption in a WSN. It tells the network when and how to access the medium. Time Division Multiple Accesses (TDMAs) are well suited for these real time applications. Because it prevents radio interference, and reduces energy consumptions. In
