Abstract


In recent years, mobile Ad hoc networks are widely used in military and civil applications, its survivability and network energy consumption to become a hot topic. In this paper, graph theory, complex networks theory, computer simulation, and other disciplines of knowledge, research mobile model node distribution of its combat survivability based on network energy consumption in mobile Ad hoc network topology survivability analysis proposed improved natural connectivity method, to establish a the survivability comprehensive measure model evaluation, and topology survivability analysis, optimization and application. The main research work and innovations are as follows: improved RWP mobility model, lower mobile model combat survivability modeling, analysis of the impact. Analysis of the the RWP model node distribution law, pointed out that the node distribution generated by edge effects \Analysis of the causes of the \Introduced a new mobile Ad hoc network topology survivability measure - spectral measure method proposed the improved natural connectivity calculation method applied to the weighted network, and analysis. Mobile Ad hoc network topology Measurement of large amount of calculation may not fully reflect the strength of network invulnerability drawbacks, the introduction of the spectral measure method to measure network survivability. Spectral measure mobile Ad hoc network adjacency matrix eigenvalue spectrum and network topology survivability link up, starting from the network's internal structure attributes characterize network survivability, a simple mathematical form, and the smaller amount of computation. Analysis of the scope of application of the natural connectivity for mobile Ad hoc network characteristics, improved method applied to the weighted network of natural connectivity, making it suitable for mobile Ad hoc network topology survivability measure. Considering mobile Ad hoc network topology survivability and network energy consumption, a dynamic network topology survivability comprehensive measure model assessment index is a measure of network energy consumption and survivability. Analysis of the relationship between network energy consumption and topology survivability. Continuous time discrete to continuous changes in the movement process discretized into a measure static network using an improved definition of the natural connectivity, to calculate static network survivability. The relationship between the network survivability and network energy consumption at the same time, the establishment of a comprehensive survivability based on energy consumption and anti-measure model, a comprehensive measure indicators. Simulation results show that, under the conditions of a given node initial energy and energy threshold, the model can calculate the nodes that meet the requirements of invulnerability optimal launch radius.
