dc.description.abstract | Since it was found that real mobility processes exhibit significant degree of correlation (<italic>correlated mobility</italic>) and nodes are often heterogeneously distributed in clustered networks (<italic>cluster scalability</italic>), there has been a great interest in studying their impact on network performance, such as throughput and delay. However, limited works have been done to investigate their impact jointly, which may due to the challenges in capturing both features under a unified network model. In this paper, we focus on their impact on asymptotic connectivity and propose <italic>correlated mobile</italic> <inline-formula> <tex-math notation="LaTeX">k </tex-math></inline-formula>-hop clustered network model. Two connectivity metrics are considered. One is network connectivity <italic>with probability (w.p.)</italic>. The other is connectivity <italic>almost surely (a.s.)</italic>, which requires a stronger condition than connectivity with probability. With mobility correlation and cluster scalability vary, we show that there are three distinct states for network connectivity, i.e., <italic>cluster-sparse</italic>, <italic>cluster-dense state</italic>, and <italic>cluster-inferior dense state</italic>, respectively. We first prove the exact value of the critical transmission range for each state, respectively, and then further generalize the three states into a unified one, which we call it <italic>cluster mixed state</italic>. The critical transmission range for connectivity <italic>almost surely</italic> is <inline-formula> <tex-math notation="LaTeX">\sqrt {2} </tex-math></inline-formula> times the range for connectivity with <italic>probability</italic>. Our main contribution lies in how to group correlated nodes into independent ones in various settings, and reveals the interrelated relationship between correlated mobility and cluster scalability through state transitions. | en_US |
