Abstract

A framework for advanced data processing in a multi-hop network is proposed and implemented in this paper. In the case of a distributed mobile DB, SQL queries are issued to multiple relational tables held by mobile nodes in MANET. Instead of collecting these tables through multi-hop network and executing the queries after collection, a part of data processing is executed at a relay node during the multi-hop data transmission, i.e., executing the SQL queries issued on the dispersed relational tables. In this paper, basic characteristics of a multi-hop environment are examined. A part of middleware is implemented for the execution of advanced function in the relay node. According to the experimental result on the middleware, the proposed framework works well in a multi-hop environment.
