Abstract: For the purpose of energy conservation, a new routing algorithm named MH-TO was proposed based on the idea of the minimum hop routing. The new algorithm optimized the network topology through a power control method of half-match mechanism. Then a "tower model" was introduced to make that all nodes obtain minimum hop information. The packet was sent by the minimum hop path to the sink node when routing. According to the analysis and the simulation results, compared with the self-organized algorithm based on minimum hop, the new algorithm can save energy and balance energy consumption, which extends the life cycle of WSN.
