Optimized link state routing (OLSR) is a routing protocol that has a small
delay, low traffic control, support the application of denser networks, and
adopts the concept of multipoint relays (MPR). The problem of OLSR is
routing table updating which continually causes excessive packet delivery,
and energy consumption becomes increased. This article proposes the
improvement of OLSR performance using the min-max algorithm based on
the quality of service (QoS) with considering the density of the node. The
Min-max algorithm works in selecting MPR nodes based on the largest
signal range. The QoS parameters analyzed with a different number of nodes
are packet delivery ratio (PDR), throughput, delay, energy consumption, and
topology control (TC). Simulation result of network simulator version 2 (NS-2) shows that OLSR performance using the min-max algorithm can increase
PDR of 91.17%, packet loss of 60.77% and reduce topology control packet
of 8.07%, energy consumption of 16.82% compared with standard OLSR.
