Abstract

The end-to-end reliable data transport is one of important issues in large-scale wireless sensor networks (LS-WSNs). In this paper, the reliable data transport protocol, called the Data Forwarding Protocol (DFP), is proposed to improve the performance in wireless sensor environments consisting of mobile sensor nodes with low speed. The key idea of the protocol is that an Agent Host (AH), which plays rule of a source or a sink, estimates multi-split connections, to support reliable end-to-end deliver. Using AH nodes, the DFP locally performs local error control and flow control mechanism with low overhead in terms of an end-to-end connection. We evaluate the proposed DFP method using NS-2 simulator and prove that the performance of reliable delivery service can be increased to at least 30%, compared with that of traditional TCP-like end-to-end approach.
