Chapter 15 Quiz

Question:

List 3 main characteristics of a wireless ad hoc network

Answer:

  • Wireless ad hoc networks are distributed networks that do not require fixed infrastructures to work. Network nodes in a wireless ad hoc network can be randomly deployed to form the wireless ad hoc network.
  • Network nodes will forward network packets for other network nodes. Network nodes in a wireless ad hoc network directly communicate with other nodes within their ranges. When these networks communicate with network nodes outside of their ranges, network packets will be forwarded by the nearby network nodes; and, other nodes that are on the path from the source nodes to the destination nodes.
  • Wireless ad hoc networks are self-organizing. Without fixed infrastructures and central administration, wireless ad hoc networks must be capable of establishing cooperation between nodes on their own. Network nodes must also be able to adapt to changes in the network, such as the network topology.
  • Wireless ad hoc networks have dynamic network topologies. Network nodes of a wireless ad hoc network connect to other network nodes through wireless links. The network nodes are mostly mobile. The topology of a wireless ad hoc network can change from time to time, since network nodes move around from within the range to the outside, and new network nodes may join the network, just as existing network nodes may leave the network.

Discussion:

  • What makes ING work?
  • How should Management Countermeasures be implemented?
  • Why does a mesh network need both routers and clients that act like routers, isn't either one sufficient?
  • If security measure such as WEP and WPA have been improved and things such as WPA2 are so much more secure, why is WEP still in use?
