A flexible node scheduling scheme of minimum delay and energy efficient for wireless sensor networks

摘要

Wireless sensor networks and artificial immune systems are both self-managed distributed systems. This paper models a system mathematically to nodes route scheduling problem of global energy consumption and delay, and proposes a node scheduling scheme for minimum delay and energy efficient for wireless sensor network using the immune clone algorithm. The proposed scheme regards one data transmission at a certain moment as an antigen, potential routes as antibody and the delay and energy consumed by the node sequence as the fitness. The simulation results show that the proposed algorithm can not only avoid the collision among sensor nodes when forwarding data packets but also solve the global optimisation problem of power consumption and delay with fast convergence speed.
