Single-constrained QoS (Quality of Service) routing
protocols have inherent shortcomings when they are
applied to ad hoc networks. Only considering a single
constraint parameter can’t always cope with the
problems aroused by the uncertainty of ad hoc
networks well. This paper proposes a multiconstrained
QoS routing protocol based on fuzzy logic.
The protocol is service-aware. It considers the QoS
requirements asked by different kinds of services and
takes different network state parameters as the
constraint conditions. New route informing mechanism
is proposed to support route update; speed of packets
sending is adjusted in terms of the output of fuzzy
system; and routing algorithm for real time traffic is
optimized to assure that data are always transmitted
through the route with the lowest delay. The simulation
results show that the improved protocol has better
features on delay, delay variation, packet loss rate and
throughput compared to single-constrained QoS
routing protocol.
