To solve this problem, based on the concept of graph theory we give a few models and arithmetic designs of virtual backbone in the environment of different application, and propose the corresponding routing mechanism with these virtual backbones. The major achievements are outlined as follows:The state of host's power or the time of host's online plays an important role in keeping stability of a virtual backbone. With a view to this feature, the paper introduces a simple and efficient heuristic algorithm for calculating the virtual backbone by seeking a minimum connected dominating set with maximal weight. The maximality of the weight-based choice of backbone nodes guarantees that the most suitable nodes have been chosen for the role of backbone nodes so that they can properly coordinate all the other nodes and keep stability of the virtual backbone in the network.

However, the thermal stability of metallic coordination polymer hardly enhanced in comparison with the polymer never coordinated transitional metallic ions. The reason might be that the energy of coordinate bond formed between metallic ion and polymer was trival in comparison with that of covalent bond in polymer. It started with coordinate bond when the coordinate polymer decomposed under high temperature, so it engendered little for the thermal stability at high temperature.
