Wireless Ad hoc Networks

  Wireless ad hoc networks have special characteristics related to node mobility, node self-configuration and the lack of centralized access points (APs). However, wireless ad hoc technologies have several disadvantages when compared to traditional wireless
networks, including their limited resources, such as:

       ** Lower processing capacity
       ** Limited memory
       ** Battery dependency

  Because operations are not centralized in a single access point, information is openly distributed among the network nodes. As a result, wireless ad hoc networks are not as secure as typical wireless networks.

  Wireless ad hoc networks are usually associated with wireless mesh networks; however, these two concepts can be dealt separately.

  The essential idea of wireless ad hoc networks is that they are mobile and dynamic. This
concept is not at all new.
