Abstract :
LEACH is a hierarchy routing protocol for WSN (wireless sensor networks), which is superior to direct communication protocol, minimum-transmission-energy protocol and static clustering protocol. However, LEACH itself has some defects. In this paper LEACH-TM introduces the concept of trust, designs the cluster-head adjusting procedure and establishes multi-path with cluster-heads acting as routers. The simulation illustrates that LEACH-TM makes much progress in the reliability of data transmission, the distribution of cluster heads and the lifetime of networks.
