  • 摘要:With the emergence of technologies in mobile computing domain, people are able to access Internet and related services through small hand held devices such as mobile phones, smart phones and PDAs. Mobile devices are resource constraint as they have less memory and processing power. When such devices are used to make range queries on spatial database, the results retrieved by the query are huge number of tuples that can't be easily presented by hand held devices. This is because they have less communication bandwidth and energy. They can't show the results as it is. From this perspective, this paper presents a new way of representing a specified size of results that causes very less information loss. The result of concise range query reduces the cost of communication and also enhances usability of end users. The concise query results are compared with other normal query results. However, finding optimal solution with less information loss is not an easy problem. To achieve this many algorithms were introduced. Experimental results revealed that the proposed system is efficient
