摘要：The nature of the Low power and lossy networks
(LLNs) requires having efficient protocols capable of handling
the resource constraints. LLNs consist of networks that connect
different type of devices which has constraints resources such as
energy, memory and battery life. Using the standard routing
protocols such as Open Shortest Path First (OSPF) is inefficient
for LLNs due to the constraints that LLNs need. So,
IPv6 Routing Protocol for Low-Power and Lossy Networks
(RPL) was developed to accommodate these constraints. RPL is a
distance vector protocol that used the object functions (OF) to
define the best tree path. However, choosing a single metric for
the OF found to be unable to accommodate applications
requirements. In this paper, an enhanced (OF) is proposed
namely; OFRRT-FUZZY relying on several metrics combined
using Fuzzy Logic. In order to overcome the limitations of using
a single metric, the proposed OFRRT-FUZZY considers node
and link metrics. Namely, Received Signal Strength Indicator
(RSSI), Remaining Energy (RE) and Throughput (TH). The
proposed OFRRT-FUZZY is implemented under Cooja
simulator and then results were compared with OF0, MHROF in
order to find which OF provides more satisfactory results. And
simulation results show that OFRRT-FUZZY outperformed OF0
and MHROF.
