PUBLISHING AND QUERYING DATA SEARCH SYSTEM FOR LARGE-SCALE MOBILE WIRELESS NETWORKS USING EFFICIENT HYBRID PROTOCOL

Abstract

This paper mainly concentrates on a data search problem where there is a huge usage of the internet now a days. Due to this, in a large scale network it is difficult to fetch the data from the nodes into a wireless network. Because of high overhead, the nodes will fail to fetch the data flexibly from the nodes and they cannot give the query service as we expect. Locality based distributed Data search system (LORD) is been used in the paper in order to overcome this problem. To increase the efficiency, we use Efficient Hybrid Routing protocol which reduces the complexity to find angle of arrival information which is needed for the existing method region based geographic routing protocol. Also piggybacking algorithm is used instead of backtracking algorithm for updating when one node moves into another region. The data will be published to a particular zone in a large network. When a user receives a metadata query from the user node, the file will be fetched directly from the particular zone and retrieves the data to the user.
