Abstract
We propose a Node Stability Index (NSI)-based algorithm to determine stable connected dominating sets (CDS) for Mobile Ad hoc Networks (MANETs). The NSI of a node is defined as the sum of the predicted Link Expiration Times (LETs) of the links with its neighbor nodes. The NSI-CDS algorithm prefers to include (to the CDS) covered nodes that have the largest NSI value, computed based on the sum of the LETs of the uncovered neighbors. The NSI-CDS has been observed to have significantly longer lifetime than the maximum density-based CDS (MaxD-CDS) and the ID-based CDS (ID-CDS). The tradeoff is a modest increase in the CDS Node Size which however contributes significantly to the robustness of the CDS as well as to a lower hop count per path, especially in high-density networks.
