Wireless Sensor Networks are considered as a distributed database. Each sensor node captures and stores the data. Data query systems are used to fetch the data stored in the sensor devices. The data query values are similar to SQL queries. The data query is mainly affected by the routing protocols. TinyDB and Cougar data query systems are designed with common route based data query process. The single route based data query systems are not suitable to execute all query types. The dynamic routing layer based data query system is introduced to handle data query with different route selection mechanism. The route selection is done with reference to the data query and network density factors.
