Ad Hoc networks are multi-hop wireless networks where all nodes cooperatively maintain network connectivity. These types of networks are useful in any situation where temporary network connectivity is needed, such as in disaster relief. An ad hoc network here would enable medics in the field to retrieve patient history horn hospital database or allow insurance companies to tie claims from the field. Building such ad hoc networks poses a significant technical challenge because of the many constraints imposed by the environment. Thus, the device used in the field must be lightweight. Furthermore, since they are battery operated, they need to be energy conserving so that battery life is maximized.
