Energy-Aware Task Allocation in Wireless Sensor Actor Networks

Wireless sensor actor networks (WSANs) are emerging a new generation of real-time embedded systems. Real-timeliness is an important issue in WSANs to guarantee that tasks of an application are distributed based on limited computation and communication resources in the network in such a way to meet their deadline. In this paper we present an energy-aware task allocation mechanism on WSANs. We propose appropriate algorithms for sensing tasks and acting tasks. According to tuple space communication architecture, our algorithms know energy of sensor and actor nodes. We show that the proposed algorithms guarantee that the tasks complete their activities before their deadlines expire.
