Multi-hop mesh cooperative structure based data dissemination for wireless sensor networks

In this paper, we investigate the use of cooperative communications for reliable data dissemination in wireless sensor networks. We first identify the disadvantages of some existing cooperative schemes. While the previously proposed ldquomulti-hop mesh cooperative transmission structurerdquo addresses these disadvantages, it suffers from large end-to-end delays during data disseminations due to its random value-based forwarding node selection scheme. This paper proposes a novel distance-based forwarding node selection scheme that yields smaller end-to-end delays. We present extensive simulation results that verify the effectiveness of the proposed data dissemination scheme.
