Abstract
Wireless sensor networks (WSN) cannot operate in complete isolation, but must be connected to an external network. Since TCP/IP is a standard protocol for external network, connecting WSN with TCP/IP network therefore is an important issue in many WSN applications. Recently, there are many solutions proposed to integrate WSN and TCP/IP network [1-5]. Running the TCP/IP protocol directly on WSN is one of the most important solution models. In this model, a unique IP address is needed for every node in WSN. The Spatial IP Assignment (SIPA) method enables every sensor node to have an IP address by constructing address via node location [6][7]. However, it does not guarantee to assign a unique IP address to every node; adjacent nodes might be assigned the same IP address because they are so close in spatial location. This paper proposes two methods: Scan-Line IP Assignment Using Equal-Distance Partition (SLIPA-D) and Scan-Line IP Assignment Using Equal-Quantity Partition (SLIPA-Q). Both methods make sure that not only every sensor node generates a unique IP address but also the spatial relation among nodes is maintained after assignment. Our experiments show that both new methods can achieve dramatic improvements in the maximum number of nodes that can be successfully assigned, meaning that every sensor node generates a unique IP address under different distribution patterns of nodes. We could take adventage on the spatial relationship among IP addresses of sensor nodes to develop efficient routing protocol.
