Slab-based memory management scheme for sensor operating system

Abstract

Previous dynamic memory allocation schemes that had been researched for general purpose operating system cannot directly apply to the wireless sensor networks (WSNs). Because these schemes did not consider features of WSNs and its applications, they consume a lot of energy caused by long execution times, and waste the memory space caused by fragmentation. In this paper, we found features of WSNs applications and made the model which adapts these issues. Through this research, we suggest the slab allocator that reduces the execution time and the memory management space. Also, we evaluate the performance of our scheme by comparing to one of the previous systems.
