Directory facilitator for LEACH in wireless sensor network

In sensor network, energy efficiency and reliable data are very important factor, because sensors have limitation such as amount of battery, capacity of memory, and computation power. Thereby, most of sensor network consider sensor's limitation. For this reason, we propose efficient routing scheme that merges Low Energy Adaptive Clustering Hierarchy (LEACH) protocol and Directory Facilitator (DF) of Component-based Autonomic Layered Middleware (CALM).
