and the dynamic topology of nodes operating in MANET's environment.In Defence Advanced Research Projects Agency (DARPA) Packet Radio projects (Jubin et al., 1987), ad hoc networking was initiated for military applications, specifically, for dynamic wireless networks since 1970s.Accordingly, this networking is not considered to be as a new concept.For MANET, a new networking group was formed within the Internet Engineering Task Force (IETF-manet) so that the standard Internet routing support could be developed for mobile IP autonomous segments.In addition, a framework for IP-based protocols in MANET will be developed as well.In the fields of mobile IP-based networks and wireless internet, the increasing improvement in the recent IEEE standards of 802 projects for wireless networks (Broch.J et al., 1998) has raised up.A MANET can be either heterogeneous or homogeneous depending on the type of mobile nodes being involved.When all mobile nodes are of the s a m et y p eo faM A N E T ,t h i si sc a l l e dah o m o g e n e o u sM A N E T ,w h e r e a sw h e nd i f f e r e n t type of mobile nodes are involved, this is otherwise called a heterogeneous MANET.The homogeneous and heterogeneous mobile ad hoc network are shown in In Figure 2 and Figure 3 respectively.The same family of IEEE 802.11 standards is being used by MANETs.More
