Performance Study of an Adaptive Trickle Scheme for Wireless Sensor Networks

摘要

In this paper, an adaptive Trickle scheme is proposed for RPL-based networks. When the network conditions are changed and/or the minimal residual energy on the sensor node gets less than a pre-determined threshold, the Trickle-related parameters are dynamically adjusted to save more battery power on the nodes in the WSN (Wireless Sensor Network). The simulation results show that the proposed scheme improves the routing performance and effectively prolongs the network lifetime of the WSN.
