Network lifecycle is one of the main considering issues when deploying natural gas pipeline monitoring networks. For increasing monitoring lifecycle, we put forward a kind of networks deployment strategy based on cost-lifecycle. The strategy can solve the following problems: how many nodes should be deployed, which data transmission mode should be adopted, and how far the distances between neighboring nodes are. In order to avoid local optimal solution, hybrid genetic algorithm is employed to work out the deployment strategy. Numerical and simulation results show the perfect performance of the strategy. Besides, we also study the impact of path loss exponent and sensing range on the optimal networks deployment. Eventually, we compare it with two common networks deployment approaches to evaluate the effectiveness of the new strategy. © 2011 Binary Information Press December, 2011.
