Abstract: The nodes of sensor networks is a computer system based on embedded devices whose request is strict with function, reliability, cost, volume, power. In this system each task, device and connection of network all need enough memory, so selecting adaptive memory management algorithm and more effective using memory are important problem to improving system performance. Based on independently developed sensor network node operating system (SNNEOS), this paper discusses memory allotment algorithm and memory collection algorithm of memory management. An effective method of memory management is provided.
