Resumo(s)
Deterministic Synchronous Multichannel Extension (DSME) is a
prominent MAC behavior first introduced in IEEE 802.15.4e. It can
avail deterministic and best effort Service using its multisuperframe
structure. RPL is a routing protocol for wireless networks with low
power consumption and generally susceptible to packet loss. These
two standards were designed independently but with the common
objective to satisfy the requirements of IoT devices in terms of
limited energy, reliability and determinism. A combination of these
two protocols can integrate real-time QoS demanding and largescale IoT networks. In this paper, we propose a new multi-channel,
multi-timeslot scheduling algorithm called Symphony that provides
QoS efficient schedules in DSME networks. In this paper we provide
analytical and simulation based delay analysis for our approach
against some state of the art algorithms. In this work, we show that
integrating routing with DSME can improve reliability by 40 % and
by using Symphony, we can reduce the network delay by 10-20%
against the state of the art algorithms.
