The default cache strategy of Content Centric Networking(CCN) is storing at each Content Router (CR) along the deliver path. It is high cache redundancy which causes the performance of CCN degradation. Hence, finding an efficient caching mechanisms is necessary in CCN. We agree that the single attribute can not to adapt to the complex network environment. the MAC considers hop count or distance, node...
Minimum redundancy coding (also known as Huffman code) is one of the most well-known algorithm of data compression. Many efforts have been made to improve the efficiency of it. Most of them are based on the assumption that the input alphabet has been already sorted. In this paper, we propose an algorithm of calculating the minimum-redundancy codes directly with unsorted alphabet. It consumes only...
This paper presents an extension of generalized disjunctive paraconsistent relational data model in which pure disjunctive positive and negative information as well as mixed disjunctive positive and negative information can be represented explicitly and manipulated. We consider explicit mixed disjunctive information in the context of disjunctive databases as there is an interesting interplay between...
