摘要
Abstract
At present,the usage of the on-chip RAM of wireless sensor networks node is really very low,which has driven us to have designed an improved memory management mechanism based on linked list. In this mechanism , we assume that all the programs were developed under the event-driven model. After that,RAM memory of the node is divided into static and dynamic memory space. At the same time,we have imported the memory isolation technol⁃ogy,which separates the memory management structure and memory space in the memory entity. In this way ,we have achieved the purpose of managing the memory. The function test shows that the average writing speed is 500 kbit/s,if we had opened the memory swap mechanism,the usage of the RAM can almost reach 80%. Ultimately,the memory management mechanism proposed by us is an efficient solution to improve memory usage.关键词
