A Reliability-Based Routing Protocol For Vehicular Ad-Hoc Networks, James Bernsen
A Reliability-Based Routing Protocol For Vehicular Ad-Hoc Networks, James Bernsen
University of Kentucky Master's Theses
Vehicular Ad hoc NETworks (VANETs), an emerging technology, would allow vehicles to form a self-organized network without the aid of a permanent infrastructure. As a prerequisite to communication in VANETs, an efficient route between communicating nodes in the network must be established, and the routing protocol must adapt to the rapidly changing topology of vehicles in motion. This is one of the goals of VANET routing protocols. In this thesis, we present an efficient routing protocol for VANETs, called the Reliable Inter-VEhicular Routing (RIVER) protocol. RIVER utilizes an undirected graph that represents the surrounding street layout where the vertices of …
Cluster-Based Term Weighting And Document Ranking Models, Keerthiram Murugesan
Cluster-Based Term Weighting And Document Ranking Models, Keerthiram Murugesan
University of Kentucky Master's Theses
A term weighting scheme measures the importance of a term in a collection. A document ranking model uses these term weights to find the rank or score of a document in a collection. We present a series of cluster-based term weighting and document ranking models based on the TF-IDF and Okapi BM25 models. These term weighting and document ranking models update the inter-cluster and intra-cluster frequency components based on the generated clusters. These inter-cluster and intra-cluster frequency components are used for weighting the importance of a term in addition to the term and document frequency components. In this thesis, we …
