Agent-based peer-to-peer layered architecture for data transfer in Wireless Sensor Networks

Recently, there has been a growing interest in the potential use of Wireless Sensor Networks (WSNs) in many applications such as smart environments, disaster management, combat field reconnaissance, and security surveillance. Therefore, to realize their potential, there is a need of an architecture that facilities the deployment of a network that is optimized in terms of energy, query and network configuration. This paper focuses on developing agent-based peer-to-peer layered system architecture for data transfer in WSNs. The architecture has three layers: application, database and network. At each layer, agents interact as peers; however, agents at base-station are computation intensive and agents at sensor nodes require very limited energy and computing resources. The application layer is the highest layer where peers exchange data requests and results. The database layer is the middle layer where peers exchange query execution plans and the query results. The network layer is the lowest layer where peers exchange the routing information and sensor data. The proposed system is implemented in Java and mica2 motes..
