Abstract. Wireless sensor nodes are usually powered by batteries and then work for a long time after deployment, which means that the energy of nodes could become a bottleneck of network operation. To solve the problem of energy limitation of nodes in wireless sensor network, this paper proposes an energy saving routing algorithm based on whole network dormancy. The algorithm can turn all nodes, including terminal nodes, routing nodes and sink nodes, to sleep, saving energy for each node in the network. At the same time, it designs two sleep strategies, named long sleep and short sleep strategy, for routing nodes. The two strategies can further reduce consumption under the premise of not affecting energy consumption. The experimental results based on CC2630 show that: compared with exiting related algorithm, the new algorithm reduces consumption of nodes by 10%.
Today, the power line carrier communication (PLCC) technology has become a research focus in the field of communication.It is important to study on the PLCC routing algorithms, since the power line carrier channel has the characteristics of high time-variation, high noise and high attenuation. The PLCC routing algorithms that have been proposed, such as the artificial spider web routing algorithm, ant-colony based routing algorithm, and flooding algorithm etc., are feasible in principle, but their actual performance is not clear. In this paper, the method for simulation on a PLCC routing algorithm which is similar to the dynamic source routing algorithm, using OPNET, is discussed. Not only the methods for OPNET modelling but also the experimental results are presented in the paper. They have important reference values for design of a PLCC network.
