| Abstract: | An energy-efficient multi-path routing protocol for low-power and lossy networks ( RPL) distri-bution mechanism, energy-efficient routing protocol for low-power and lossy networks (EM-RPL), was proposed to solve the problem on imbalance of power consumption in RPL. Firstly, a model of node ener-gy consumption was established, which is more in line with the actual node energy consumption. Second-ly, an energy dispersion degree measurement criterion was presented. Based on this measure, a fast algo-rithm was proposed to obtain the optimal distribution of the data. Simulation results show that the im-proved RPL algorithm can balance the energy consumption of nodes, improve the reliability of routing, and prolong the lifetime of the network. |
| Keywords: | routing protocol for low-power and lossy networks energy-efficient multi-path destination oriented directed acyclic graph load balance |
