Abstract:

An energy-saving scheme for wireless sensor networks based on network coding and duty-cycle (NCDES) was proposed. The scheme determines the node's status based on the ID information which embedded in data information. When combining network coding and duty-cycle in wireless sensor networks, it will reduce transmission coding coefficients and retransmissions. The energy efficiency of the network increases as more volume of data will be transmitted to the sink with same number of transmissions. The optimal value of energy consumption for the multi-hop network was proved by analyzing the network topology and energy model. In contrast to RDCNCode and AdapCode++, the simulation shows that NCDES has a great improvement on data delivery ratio and energy efficiency, it extends the network lifetime about 4.02% and 8.51%, and improves the packet delivery rate about 14.83% and 4.65%.

Key words: wireless sensor network, network coding, duty-cycle, network lifetime, energy efficiency
