英文摘要	Conference Name:2011 International Conference on Recent Trends in Materials and Mechanical Engineering, ICRTMME 2011. Conference Address: Shenzhen, China. Time:January 27, 2011 - January 28, 2011.; Intelligent Inf. Technol. Appl. Res. Assoc.; Southern Illinoic Univetsity Carbondale; National University of Singapore; We investigate the node distribution strategy in one-dimensional linear wireless sensor networks(WSNs), which aims to avoid the energy hole around the sink. We set up the network model and analyze the energy consumption factors, such as data compression and aggregation, and propose energy balance strategies due to different placement scenarios. In the uniform node distribution scenerio, based on selected optimal hop distance, we can add more backup batteries to some nodes to balance the sensors' lifetime. In the hop distance variable scenario, we can select different optimal hop lengths. Simulation results show that, in a WSN with linear topology, aggregation and compression should be supplied with backup battery to balance energy consumptions and to maximize the network lifetime. ?
