  2. Low-energy adaptive clustering hierarchy - Wikipedia

    en.wikipedia.org/wiki/Low-energy_adaptive...

    Low-energy adaptive clustering hierarchy ("LEACH") [1] is a TDMA-based MAC protocol which is integrated with clustering and a simple routing protocol in wireless sensor networks (WSNs). The goal of LEACH is to lower the energy consumption required to create and maintain clusters in order to improve the life time of a wireless sensor network.

  3. Hierarchical state routing - Wikipedia

    en.wikipedia.org/wiki/Hierarchical_state_routing

    Hierarchical state routing (HSR), proposed in Scalable Routing Strategies for Ad Hoc Wireless Networks by Iwata et al. (1999), is a typical example of a hierarchical routing protocol. HSR maintains a hierarchical topology, where elected clusterheads at the lowest level become members of the next higher level. On the higher level, superclusters ...

  4. Mobile wireless sensor network - Wikipedia

    en.wikipedia.org/wiki/Mobile_wireless_sensor_network

    WSN routing protocols provide the required functionality but cannot handle the high frequency of topology changes. Whereas, MANET routing protocols can deal with mobility in the network but they are designed for two way communication, which in sensor networks is often not required.

  5. Wireless sensor network - Wikipedia

    en.wikipedia.org/wiki/Wireless_sensor_network

    Wireless sensor networks are composed of low-energy, small-size, and low-range unattended sensor nodes. Recently, it has been observed that by periodically turning on and off the sensing and communication capabilities of sensor nodes, we can significantly reduce the active time and thus prolong network lifetime.

  6. List of ad hoc routing protocols - Wikipedia

    en.wikipedia.org/wiki/List_of_ad_hoc_routing...

    An ad hoc routing protocol is a convention, or standard, that controls how nodes decide which way to route packets between computing devices in a mobile ad hoc network. In ad hoc networks, nodes are not familiar with the topology of their networks.

  7. List of wireless network protocols - Wikipedia

    en.wikipedia.org/wiki/List_of_wireless_network...

    Wireless Sensor Networks (WSN / WSAN) are, generically, networks of low-power, low-cost devices that interconnect wirelessly to collect, exchange, and sometimes act-on data collected from their physical environments - "sensor networks". Nodes typically connect in a star or mesh topology.

  8. Topology control - Wikipedia

    en.wikipedia.org/wiki/Topology_control

    This protocol, based on the Dynamic Source Routing (DSR) routing algorithm, recreates the paths of disconnected nodes when a node fails. In all of the above protocols can be found in. [10] In Atarraya, [11] two version of each of these protocols are implemented with different triggers: one by time, and the other one by energy. In addition ...

  9. Hierarchical routing - Wikipedia

    en.wikipedia.org/wiki/Hierarchical_routing

    Most Transmission Control Protocol/Internet Protocol routing is based on a two-level hierarchical routing in which an IP address is divided into a network portion and a host portion. Gateways use only the network portion until an IP datagram reaches a gateway that can deliver it directly. Additional levels of hierarchical routing are introduced ...
