Abstract
Wireless Sensor Networks (WSNs) have been recognized
as a crucial and enabling technology in the world of
Internet of Things (IoT). However, their integration with IoT
arises new design challenges, compared to conventional WSNs
applications. This paper addresses the challenge of high node
density and its impact on the design of IoT-WSNs routing protocols.
We propose a power-aware topology control mechanism
built upon the prominent routing scheme, Directed Diffusion.
Moreover, we take benefit from the power-awareness feature of
the topology control mechanism in order to compute an energy
consumption metric, allowing the selection of energy-efficient
routes. The simulation results demonstrate an improvement by
the proposed protocol in terms of energy efficiency, data reporting
delays and delivery success rate.
