Distributed assignment of real-time tasks in wireless sensor actor networks

Abstract

To achieve more cost-effective assignment of real-time tasks to actors in wireless sensor actor networks we propose a distributed auction-based protocol that uses tasks' deadlines, actors' energies, actors' loads and actors' distances from event area as a cumulative cost metric. The protocol chooses actors closest to event area with lowest loads and highest remaining energies to minimize the response time of tasks, balance loads on actors and maximize total remaining energy of actors. Simulations show higher deadline meet-ratio and remaining energies of actors, and more balanced loads on actors, compared to SAP and SAAP task-assignment protocols.

A Novel Event Detection Framework for Wireless Sensor and Actor Networks

“…The coordination between sensors and actors can establish paths to transmit data and help actors to find related positions or precise locations of events. After receiving event data, actor nodes need to cooperate with each other to make correct decisions and finish related tasks [15]. In this paper, 3-CEDF utilizes three-layer cooperation relations in WSAN to make normal sensor nodes, cluster-head nodes and actor nodes work together, which reducing energy consumption and prolonging working life of WSAN.…”
