Adhoc netwoking Architecture and Research
The specific MANET issues and constraints described above pose significant challenges in adhoc network design. A large body of research has been accumulated to address these specific issues, and constraints. In this paper, we describe the ongoing research activities and the challenges in some of the main research areas within the mobile ad hoc network domain. To present the huge amount of research activities on ad hoc networks in a systematic/organic way, we will use, as a reference, the simplified architecture shown in Figure
Figure : A simple MANET architecture
As shown in the figure, the research activities will be grouped, according to a layered approach into three main areas:
• Enabling technologies;
• Middleware and applications.
In addition, as shown in the figure, several issues (energy management, security and cooperation, quality of service, network simulation) span all areas, and we discuss them separately.
