Research Of WSN Protocol Based On Energy

Wireless sensor network (WSN) is a new technology. It appeared after sensor technology, computer technology, and MEMS technology developed. As a new technology of information collection, WSN is paid more attention in a lot domain. It's used in environment inspection, military spy, medical treatment, counterstrike, etc.Because of the bad working circumstance and complex working terrain, replace batteries for WSN is impossible. So energy problem is a important problem no matter in hardware or software design. Especially in large-scale WSN, how to design special protocol to save energy is that people care about. This thesis main made a research of software. Analyze the principle and system emulation of LEACH routing protocol based on data collection and improved LEACH routing protocol contrapose the bug in cluster head election. Besides, in this thesis also introduced PEGASIS routing protocol and designed a new routing protocol by the way of combining LEACH and PEGASIS.
