NT 1310 NETWORK TOPOLOGY PAPER: KENDAL JEFFERSON Network topology refers to layout of a network and how different nodes in a network are connected to each other and how they communicate. Mesh Topology: in a mesh network‚ devices are connected with many redundant interconnections between network nodes‚ in a true mesh topology every node has a connection to every other node in the network. There are two types of mesh topologies: Full mesh occurs when every node has a circuit connection it to every

Logical vs. Physical Design of a Network In the world of network design‚ there are two common design types; the logical network design and the physical network design. A logical network design can be described as how the network will be structured‚ basically all logical aspects of the network. According to Webopedia‚ "the logical topology is the way that the signals act on the network media‚ or the way that the data passes through the network from one device to the next without regard to the

Performance Issues of Routing Protocols in MANET ABSTRACT A mobile ad-hoc network is an assortment of wireless mobile hosts‚ which establishes a momentary network without any assist of centralized administrator. The characteristics of an ad-hoc network can be explored on the base of routing protocols. The dynamic topology is the vital characteristic in which nodes frequently change their position. In the ad-hoc networks‚ there are mobile nodes such as personal digital assistance (PDA)‚ smart phone

The internet is a network of networks that consists of millions of private‚ public‚ academic‚ business‚ and government networks‚ of local to global scope‚ that are linked by a broad array of electronic‚ wireless and optical networking technologies. From work to school‚ living room to shopping malls and restaurants‚ internet follows us everywhere and has become an essential part of our lives and in today’s world‚ life without internet cannot be imagined. In short‚ the internet has conquered every

wide area network that connects computer systems around the globe. I order to understand the internet one must look to the basic network. There are two types of networks. Peer to peer (P2P) and Client / provider networks. In a peer to peer network no node has more authority than another node. File sharing is possible on a P2P network but there may be multiple copies of a document at different revision states. It is for this reason that corporations and firms use Client provider networks at their

Norman Abramson‚ a professor at the University of Hawaii‚ developed the world’s first wireless computer communication network‚ ALOHAnet (operational in 1971)‚ using low-cost ham-like radios. The system included seven computers deployed over four islands to communicate with the central computer on the Oahu Island without using phone lines. Definition A wireless local area network (WLAN) links two or more devices using some wireless distribution method (typically spread-spectrum or OFDM radio)‚ and

LOAD BALANCING ROUTING PROTOCOL ON MULTIHOP WIRELESS NETWORKS ABSTRACT A Multihop wireless Network have the potential to extend the coverage of a network which composed of mobile nodes where the two nodes can communicate through the number of intermediate nodes in wireless links. Multihop mesh networks‚ Multihop cognitive radio networks‚ sensor networks‚ iMANET‚ vanet are all the examples of Multihop wireless networks. To improve the network performance‚ Load Balancing in Routing mechanism is considerable
