الملخص الانجليزي
The Optimal Link State Routing (OLSR) protocol employs multipoint relay (MPR) nodes to disseminate
topology control (TC) messages, enabling network topology discovery and maintenance. However, this
approach increases control overhead and leads to wasted network bandwidth in stable topology scenarios
due to fixed flooding periods. To address these challenges, this paper presents an Efficient Topology
Maintenance Algorithm (ETM-OLSR) for Enhanced Link-State Routing Protocols. By reducing the number
of MPR nodes, TC message generation and forwarding frequency are minimized. Furthermore, the
algorithm selects a smaller subset of TC messages based on the changes in the MPR selection set from the
previous cycle, adapting to stable and fluctuating network conditions. Additionally, the sending cycle of TC
messages is dynamically adjusted in response to network topology changes. Simulation results demonstrate
that the ETM-OLSR algorithm effectively reduces network control overhead, minimizes end-to-end delay,
and improves network throughput compared to traditional OLSR and HTR-OLSR algorithms.
