Hierarchical routing is the procedure of arranging routers in a hierarchical manner. A good example would be to consider a corporate intranet.Most corporate intranets consist of a high speed backbone network.
The distribution layer is the smart layer in the three-layer model. Routing, filtering, and QoS policies are managed at the distribution layer. Distribution layer devices also often manage individual branch-office WAN connections.
The hierarchical network model is part of the scale-free model family sharing their main property of having proportionally more hubs among the nodes than by random generation; however, it significantly differs from the other similar models (Barabási–Albert, Watts–Strogatz) in the distribution of the nodes' clustering coefficients: as other models would predict a constant clustering ...
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.
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 ...
The Optimized Link State Routing Protocol (OLSR) is a link-state routing protocol optimized for mobile ad hoc networks (which can also be used on other wireless ad hoc networks). [17] OLSR is proactive and uses hello and topology control messages to disseminate link-state information into the mobile ad hoc network.
The DCell follows a recursively built hierarchy of cells. A cell 0 is the basic unit and building block of DCell topology arranged in multiple levels, where a higher level cell contains multiple lower layer cells. The cell 0 is building block of DCell topology, which contains n servers and one commodity network switch.
The network routing architecture then became decentralized and this meant a need for exterior routing protocols: in particular, the Border Gateway Protocol emerged. New Tier 1 ISPs and their peering agreements supplanted the government-sponsored NSFNet, that program being officially terminated on April 30, 1995. [ 7 ]
