. Applications-Theset of applications for mobile networking is diverse, ranging from large-scale,mobile, highly dynamic networks, to small, static networks that are constrainedby power sources. Besides the legacy applications that move from traditionalinfra structured environment into the ad hoc context, a great deal of newservices can and will be generated for the new environment.1.

Security and Reliability3. Quality of Service (QoS)4. Inter-networking5.
Power Consumption6. Multicast7. Location-aided Routing 6.
Conclusion and Future Scope-Thefuture of mobile networking is really appealing, giving the vision of ?anytime,anywhere and cheap communications. Before those imagined scenarios come true,huge amount of work is to be done in both research and implementation. At present,the general trend in mobile networking is toward mesh architecture and largescale. Improvement in bandwidth and capacity is required, which implies theneed for a higher frequency and better spatial spectral reuse. Propagation,spectral reuse, and energy issues support a shift away from a single longwireless link (as in cellular) to a mesh of short links (as in ad- hoc networks).Large scale mobile networking is another challenging issue in the near futurewhich can be already foreseen. As the involvement goes on, especially the needof dense deployment such as battlefield and sensor networks, the nodes inad-hoc networks will be smaller, cheaper, more capable, and come in all forms.In all, although the widespread deployment of ad- hoc networks is still yearaway, the research in this field will continue being very active andimaginative.
