ROUTING TABLE GENERATING METHOD AND APPARATUS BASED ON USER INTEREST, ROUTING TABLE UPDATING METHOD, APPARATUS AND METHOD FOR PROCESSING CONTENTS

摘要

PURPOSE: A routing table based on user interest, an apparatus for composing a routing table, a routing table updating method, an apparatus, and a method for processing contents are provided to obtain contents more rapidly and reduce network burden caused by various requests for identical contents, thereby more efficiently supporting applications, such as a content sharing application. CONSTITUTION: A routing table configuration apparatus includes a routing table management unit(100), an effectiveness calculation unit(110), a storage unit(120), and a routing path setting unit(130). The routing table management unit generates an initial routing table by receiving the interest information of users of respective mobile nodes and then stores the initial routing table in the storage unit. In paths of the initial routing table, the mobile node is set as a destination node, and the interest information of the user is set as well. Further, the routing table management unit generates an update message required to update the routing tables of neighboring nodes by using the initial routing table and sends the update message to the neighboring nodes by broadcasting the update message through the mobile ad hoc network. That is, the routing tables stored in the storage units of respective nodes are exchanged with each other through a periodic broadcast. Each node stores therein all received routing tables. That is, by storing the received paths to a destination, all possibilities can be considered. When a routing table is broadcasted via a chosen single path, network overhead can be reduced.
