Abstract

In this paper, we propose a protocol for downstream communication in a wireless sensor network (WSN) based on the Postorder Numbering (PN) scheme in a tree. The existing solutions are either based on mesh routing or on full dissemination. Mesh routing is not suitable for large collection networks, while dissemination based routing can not address individual nodes. PN routing requires parent information, and postorder numbering for addressing individual nodes for routing the packets downstream. We combine PN routing with the concept of NATing to provide a simple light weight transport protocol independent of application. The transport layer of the PN routing is merged with that of a tree based collection protocol for upstream routing to provide a seamless integration of IP network with WSN.
