Adaptive Management of Scalable Mobile Ad-Hoc Networks with Non-homogeneous Topology

In this paper, we discuss the management of scalable mobile ad-hoc networks (MANET) in which nodes are equipped with a range of adjustable capabilities (transmission range, data rate, and radio interface, etc.) and operate in quite diverse environment (in terms of channel condition and node density, etc.). To support communication in such a dynamic networking environment requires a MANET protocol that is adaptable to spatial and temporal changes. As such, it is crucial to optimize node/link controllability so that node/link resources can be best utilized and a good performance can be achieved. Moreover, it is also necessary to feature statistical measures when evaluating the performance, such as the variance of these metrics in addition to the average. As an extension of our previous research, we continue to study Adaptive Hybrid Domain Routing (AHDR) protocol in regard to the effectiveness of the flooding architecture. We also evaluate various topology control techniques that ensure guaranteed service to disadvantaged nodes and across critical links (sparse connectivity). These efforts serve as very first steps to comprehensively study the impact of network non-homogeneity and variance in topology management.
