What is the difference between wireless mesh networks and mobile ad hoc networks?
A wireless mesh network is a type of ad hoc network. The difference would be that clients on mesh networks are dedicated to the role of routing by relying on an infrastructure of sorts, while ad hoc clients are generally user to user and not fixed to any kind of infrastructure.
Will ad-hoc networks contain access points?
An ad-hoc network does not require an access point. Typically, if an access point is involved then it is not strictly an ad-hoc network, but would be an infrastructure network.
What are the advantages and disadvantages of adhoc networks?
Advantage: Easy to set up Cheap Disadvantage: Lack of security. Thus ad-hoc network is also called unsecure networks.
What is ad hoc networks?
Mobile ad hoc networks refer to the networks that cellphones and other mobile devices are connected to. Laptops and computers may also connect to such networks by means of tethering to a mobile device.

Why csma CD not applicable in mobile ad hoc networks?
Because CSMA/CD does not prevent Hidden terminal problem. so it is onlly applicable in Wired networks.
What is the difference between wireless ad hoc networks and mobile ad hoc networks?
A mobile ad hoc network (MANET) is a self-configuring infrastructureless network of mobile devices connected by wireless.Each device in a MANET is free to move independently in any direction, and will therefore change its links to other devices frequently. Each must forward traffic unrelated to its own use, and therefore be a router. The primary challenge in building a MANET is equipping each device to continuously maintain the information required to properly route traffic. Such networks may operate by themselves or may be connected to the larger Internet.MANETs are a kind of wireless ad hoc networks that usually has a routable networking environment on top of a Link Layer ad hoc network.A wireless ad hoc network is a decentralized type of wireless network.[1] The network is ad hoc because it does not rely on a preexisting infrastructure, such as routers in wired networks oraccess points in managed (infrastructure) wireless networks. Instead, each node participates in routing by forwarding data for other nodes, so the determination of which nodes forward data is made dynamically on the basis of network connectivity.
What is infrastructureless network?
Probably the most quickly developing areas in wireless networks is wireless ad hoc networks. A wireless ad hoc network is an autonomous system consisting of nodes, which might can become mobile, connected with wireless links and without using pre-existing communication infrastructure or central control. Ad hoc networking is expected to play an important role in future wireless mobile networks because of the widespread use of mobile and hand-held devices. Mobile Ad hoc Networks (MANETs) and Wireless Sensor Networks (WSNs) are two prominent classes of these infrastructerless wireless networks. While MANETs exhibit dynamic topology changes due to free node mobility, WSNs have unreplinishible energy limitations. Hence, topology control, Quality of Service (QoS) routing, and power control become challenging issues.
What mode requires a wirless access point?
Infrastructure mode requires an access point. Ad-hoc does not.
Are wireless networks laid out using the same topologies as wired networks?
Wireless networks are not laid out using the same topologies as wired networks. They have their own, different layouts. Smaller wireless networks, in which a small number of nodes closely positioned need to exchange data, can be arranged in an ad hoc fashion.
