As the routing protocol can greatly influence the energy consumption of the sensor nodes in research field of wireless sensor networks. In this paper, we present a novel distributed hash table based routing algorithm for wireless sensor networks. Distributed hash table is a kind of distributed memory approach, of which the single node can be expanded to the whole Internet. Particularly, each node...
The distributed routing protocol is widely used in wireless sensor networks. But it is mainly designed for homogeneous networks and also has the disadvantages of irrationality of choosing cluster head and unbalanced energy consumption of nodes. Through theoretical studies, a new protocol of the cluster multi-hop transmission (CMHT) for heterogeneous sensor networks is proposed. The algorithm selects...
The consumption of final energy and consumptions of different varieties of energy in Beijing from 1990 to 2006 are presented using data from the China Energy Statistical Yearbook 2007 and Beijing Statistical Yearbook 2007. Energy-CO2 emission in Beijing was calculated by sector and fuel type using the Intergovernmental Panel on Climate Change reference approach and statistical data, and the relationship...
Energy problem is universally concerned all over the world. Over the years, as China paid more attention on energy problem seriously, China's energy consumption per unit GDP has decreased continually, but there is still a big gap between China and the developed countries, especially in the last five years, energy consumption per unit GDP fell slowly. To further improve the efficiency of energy use,...
