Dependency on network connectivity is a growing need in the technology driven world of today. Whether communication or the transport of large quantities of data is the primary goal, speed and accessibility are major factors that need to be taken into consideration. Sluggish data rates are everything but desirable considering the multimedia rich Internet. With regard to accessibility, wireless technologies have taken a leap in the direction of being connected wherever you are. The dependency on a fixed infrastructure limits the scalability of networks. Even with wireless networks nodes are bound by the range of a given sender. Extending the physical range of the Internet, for instance, can thus become a tedious and expensive task. A self-organising, self-configuring, multihop wireless alternative to the traditional infrastructured cellular system, is called a mobile ad hoc network (MANET). Ad hoc networks consist of nodes, all acting as active routers. Information is thus relayed in a multihop fashion across the network to the desired destination. An efficient routing strategy is thus crucial, since mobile nodes can join and leave the network. The dynamic nature of such a system gives it its value, but adds complexity to the protocols governing its behaviour. The broad purpose of the research is the design of an efficient and scalable ad hoc routing protocol, and to do a performance comparison of it with various other protocols.
