Abstract
Delay Tolerant Wireless Sensor Networks (DT-WSN) are sensor networks sparsely populated where connectivity between sensor nodes is intermittent. The energy consumption is critical to the performance of these networks, since nodes have to carry data for a long period of time due to opportunistic transmissions. This work presents a multi-hop cooperative multiple/single input multiple/single output (C-XIXO) transmission scheme for DT-WSN in order to achieve longer communication ranges and consequently reduce the message delivery time to the sink, maximizing the energy efficiency. Simulations results suggest that the proposed scheme provides higher message propagation speed and reduced energy consumption compared to a state-of-the-art scheme for DT-WSN.
