DANCE: Distributed application-aware node configuration engine in shared reconfigurable sensor networks

Wireless sensor networks (WSNs) are often primarily tailored to single applications to achieve one specific mission. Considering that the same physical phenomenon can be used by multiple applications, the benefit of sharing the WSN infrastructure is obvious in terms of development and deployment cost. However, allocating the tasks to the WSNs to meet the requirements of all applications while keeping the energy efficiency is very challenging. Introducing reconfigurable nodes in the shared sensor networks can improve the performance, the energy efficiency and the flexibility but it increases the system complexity. In this paper, we propose a biologically inspired node configuration scheme in shared reconfigurable sensor network named DANCE, which can adapt to the changing environment and efficiently utilize WSN resources. Our experiments show that our scheme reduces the energy consumption by up to 76%.
