Updating sensor node programs is an essential task for maintaining stability and modifying the characteristics of wireless sensor networks. The updating mechanism must consider energy and memory efficiency, because of resource constraints of sensor nodes. In this paper, we propose a novel program updating mechanism, which considers resource constraints of sensor nodes. The proposed mechanism was designed for sensor nodes with the NOR flash memory. This is generally used to store program image. It was designed to minimize the number of flash write/erase operations, which consume a great deal of energy, and to provide wear-leveling for the NOR flash memory. We set a function as the basic unit of program updating, and partition a function into fixed-sized blocks that can be separately relocated in memory. Experimental results show that the proposed mechanism outperforms other mechanisms in terms of energy, memory and wear-leveling for flash memory.
