In this paper, the authors proposed a novel Backbone tree topology for the data gathering in wireless sensor networks. By integrate the ideas of both linear chain and tree topology, the new Backbone tree topology obtains quicker network responding speed and longer lifetime results. With the introduction of low-cost processor, memory, and radio technologies, it becomes possible to build inexpensive wireless micro-sensor nodes. These networks can be used to collect useful information from an area of interest, especially where the physical environment is so harsh that the macro-sensor counterparts cannot be deployed.
