RDTP: reliable data transport protocol in wireless sensor networks

摘要

The paper deals with a new reliable data transport protocol forwireless sensor networks, referred as RDTP. One of the most prominent challenges in wireless sensor networks is reliable transport of data from sensor nodes to sink node. For designing protocols for such networks hardware, some constraining factors associated with energy and processing power must be taken into consideration. There are two generic methods, ARQ and FEC to achieve reliable data transport. Here, a reliable data transport protocol for wireless sensor networks is proposed, in which an efficient moduli set in redundant residue number system has been employed. Themodulus set is exploited as a means for adding redundancy to transmitted data. Error controlling in proposed method is performed in a hop by hop manner. The simulation results indicate that the proposed method shows significant decreases in the energy consumption, compared to similar methods. The results also show that this leads to a rise in packet delivery ratio, with a simultaneous reduction in end to end delay.
