A low-rate, short-range wireless radio communication naturally requires complementary functions to achieve reliability in wireless sensor networks. The well-known protocol is MINT, which is deployed in TinyOS. However, link quality metric like packet reception rates employed in MINT causes huge number of path changes because packet reception rates is drastically affected by many several parameters. Thus, unnecessary delay and packet loss are inevitably brought. In this paper, we propose a new metric for link estimation, which works with MINT to improve the performance. It is designed to take cross-layered principle in wireless sensor networks as well as several network environments into account. Simulation results reveal that current scheme for link quality is not enough to estimate the quality on link. In addition, more reliable links are chosen so less frequent procedures for parent selection are invoked in the proposed scheme.
