RIOT is a small operating system for networked, memory-constrained systems with a focus on low-power wireless Internet of things (IoT) devices. It is open-source software, released under the GNU Lesser General Public License (LGPL).
A wireless ad hoc network [1] (WANET) or mobile ad hoc network (MANET) is a decentralized type of wireless network. The network is ad hoc because it does not rely on a pre-existing infrastructure, such as routers or wireless access points. Instead, each node participates in routing by forwarding data for other nodes.
That means no IP addresses must be assigned because the unique MAC addresses of the WLAN hardware is used instead. Furthermore, all kinds of layer 3 protocols can be used, like IP, DHCP, IPv6, IPX, etc. The protocol daemon creates a virtual network interface, which can be used by the kernel like a typical LAN interface.
Contiki is designed to run on types of hardware devices that are severely constrained in memory, power, processing power, and communication bandwidth.A typical Contiki system has memory on the order of kilobytes, a power budget on the order of milliwatts, processing speed measured in megaHertz, and communication bandwidth on the order of hundreds of kilobits/second.
An evolved wireless ad hoc network (EVAN) [1] is a decentralized type of wireless network that compensates for the shortcomings of the existing wireless ad hoc network (WANET). [2] An EVAN is ad hoc like a WANET because it does not rely on a pre-existing infrastructure, such as routers in wired networks or access points in wireless networks.
IEEE 802.11s is a wireless local area network (WLAN) standard and an IEEE 802.11 amendment for mesh networking, defining how wireless devices can interconnect to create a wireless LAN mesh network, which may be used for relatively fixed (not mobile) topologies and wireless ad hoc networks. The IEEE 802.11s task group drew upon volunteers from ...
Multiple Access with Collision Avoidance for Wireless (MACAW) [1] is a slotted medium access control (MAC) protocol widely used in ad hoc networks. [2] Furthermore, it is the foundation of many other MAC protocols used in wireless sensor networks (WSN). [2] The IEEE 802.11 RTS/CTS mechanism is adopted from this protocol.
Wireless grids are wireless computer networks consisting of different types of electronic devices with the ability to share their resources with any other device in the network in an ad hoc manner. A definition of the wireless grid can be given as: "Ad hoc, distributed resource-sharing networks between heterogeneous wireless devices" The ...
