This technique will enable mobility sensor nodes stay at waiting in sleep mode to obtain new information/ control data at certain time for response / moving from one location to another under radio coverage area. Due to its capacity of handling large data, graph theory is of some special interest as it can be applied to many problems including problems in management sciences (Harary 1959), social sciences (Harary and Norman 1953), computer sciences. (Introduction) For example, a colleague and I are investigating how library catalogers over the years have, at least since the mid 19th century, created graph structures within library catalogs - in their book, index card, and database record forms. Facility types are indicated by numbers in parentheses. We call a graph with just one vertex trivial and ail other graphs nontrivial. In overdeployed sensor networks, one approach to conserve energy is to keep only a small subset of sensors active at any instant. everyday life .

Rather than only exploring the user-video graph that is formulated using the click-through information, we also investigate other two useful graphs, the user-query graph indicating if a user ever issues a query, and the query-video graph indicating if a video appears in the search result of a query. Applications of Graph Coloring: The graph coloring problem has huge number of applications. (Preliminaries) This paper gives an overview of the applications of graph theory in heterogeneous fields to some extent but mainly focuses on the computer science applications that uses graph theoretical concepts. Graphs are mathematical structures used in many applications.

However, it is still very challenging to discover new video contents for users. The aim of this paper is to analyse a social network and a wife network using the concept of picture fuzzy graph (PFG). Experimental results on a dataset of 2,893 users, 23,630 queries and 55,114 videos collected during Feb. 1-28, 2011 demonstrate that the proposed method outperforms existing state-of-the-art approaches, co-views and random walks on the user-video bipartite graph. users. There are many application of graph theory in di erent branches like economics, logistics etc. We develop an iterative propagation scheme over the tripartite graph to compute the preference information of each user. Subsequently, since the message-pruning tree with minimum cost is hard to construct in polynomial time, we propose a new data aggregation structure, a message-pruning tree with shortcuts, instead of the message- pruning tree. We then show that the algorithmic problem of determining $\zeta (G)$ is NP-hard in graphs with diameter at most $2$. Graphs are everywhere (that’s how my dissertation begins). b.
