The invention discloses a method for realizing a row lock of a database in order to reduce system overhead. For example, the method can include the first step of responding to a transaction request, received into the database, of a data row and judging whether the row lock occupied by the data row exists according to the corresponding relation between the data row recorded in a row lock recording region and the row lock occupied by the data row, the second step of obtaining an idle row lock if the row lock occupied by the data row does not exist, and enabling the idle row lock to be the row lock occupied by the data row according to the corresponding relation between the data row recorded in the row lock recording region and the idle row lock, the third step of obtaining the row lock occupied by the data row according to the corresponding relation if the row lock occupied by the data row exists, the fourth step of returning the row lock occupied by the data row, and the fifth step of responding to and judging whether transactions of the data row are completely executed and canceling the corresponding relation between the data row recorded in the row lock recording region and the row lock to enable the data row to cancel occupation on the row lock. In addition, the invention further discloses a device for realizing the row lock of the database.

The invention relates to a task scheduling method for a wireless sensor network node. The method is realized based on a special operating system based on a wireless sensor network, wherein the special operating system comprises a binary code translation tool and an operating system kernel, the binary code translation tool runs on a base station node and provides a pretreatment for an application program; the operating system kernel runs on a sensor node and provides a series of kernel services; and the binary code translation tool and the operating system kernel act together to realize preemptive multi-task scheduling in the sensor node.
