Exploring TinyDB for a Low Traffic Solution and Query Optimization in Sensor Networks

Abstract: Tiny DB is a database which is exclusively used in sensor network in Tiny OS (Tiny operating system) platform. It sends queries from a server to the network and gets back the result to the server in each epoch. One of the most challenging jobs in sensor networks is to reduce the traffic and to reduce the power consumption. We have derived a technique in case of network traffic which is significantly reducing the power consumption and network traffic cost than the current system. In our system, queries will be sent to the network in the first epoch during each data collection period and in all the other epochs it will just return the results. The motes will accept and store the first query that specifies the sample period and the data collection duration. It will then use the same query for retrieving the rest of the results at the end of each sample period for the entire data collection period. We used Tiny OS simulator (TOSSIM) which is embedded with Tiny DB and Tiny OS. We hope that it will be a great achievement in case of sensor network and sensor network database area.
