Connecting sensor networks with IP using a Configurable tiny TCP/IP protocol stack

Wireless Sensor Networks (WSNs) consist of a large number of small, smart and low-cost computing devices. Offering a higher degree of flexibility, WSNs are drawing plenty of attention as methods to realize a ubiquitous society. Several sensor networks which are physically deployed in different places sometimes need to be integrated over IP to provide meaningful services for users. It will be widely used in the human society. However, connecting heterogeneous sensor networks with IP is still an open and challenging problem. Recently, implementing TCP/IP in sensor networks attracts much interest nowadays. In this paper, based on the existing researches, we propose a configurable tiny TCP/IP protocol stack integrated with Session Initiation Protocol (SIP) module for a WSN. Using it, we can customize the different protocol set of tiny TCP/IP stack based on the different resource conditions of sensor nodes. Our research has been mostly conducted both in a simulator environment and on physical sensor nodes. The implementation of the configurable tiny TCP/IP protocol stack allows the users to query, control and monitor in different WSNs.
