It presents scenarios which require the identification and subsequent choosing of the most appropriate approach and methodology to be used in the development of an information systems for that scenario. The available approaches and methodologies are presented, discussed and scrutinized and the most appropriate approach and methodology for the situation given is chosen, with justifications.

Unlike traditional wired or wireless networks MANETs do not have a fix infrastructure or a central point of control. It is made up of a number of mobile devices that self-configure to form a network, randomly. Devices can join and leave the network at will but once part of the network they are considered nodes.
These nodes are responsible for the full functionality of the network; i.e. switching, routing and security whilst at the same time being transmitters and receptors of information.
Since the nodes are the routers themselves they communicate with each other directly or via other nodes if outside of the scope of the other's radio range. Many protocols have been developed to determine how best the data packets should be moved from one node to another, however, since any of these nodes can move about freely, die "loose power" or leave the network, the routes from one node to another can be constantly changing to the point where certain nodes may become isolated from the rest of the network.
Fundamental to the existence and functionality of MANETs is their power source, a large percentage of which is consumed by their communication devices (transmitters & receptors) however power consumption does not always mean data transmission, i.e. the difference in energy consumption by an active node when it is transmitting data and when it is idle is very small.
For the purpose of this research we look at the importance of conserving energy in battery dependent MANETs through the use of protocols and schemas. The study is divided into five sections. The first section, the Introduction which answers the question, "What is MANET and why is there are need for it?" is followed by section 2 which gives an explanation of the technology.
