OCI-OLSR: An Optimized Control Interval-Optimized Link State Routing-Based Efficient Routing Mechanism for Ad-Hoc Networks

Abstract

MANET (Mobile Ad hoc Networks) functionality is determined by routing protocols’ ability to adjust to atypical changes in information and communication technologies, topological systems, and connection status. Due to interference, node migration, the growth of several pathways, security, and propagation loss, MANET network configurations are dynamic. The proactive routing protocol enhances the message flow utilized in the neighborhood discovery process by using the multipoint relays (MPR) approach. In order to increase the protocol’s effectiveness and efficiency while maintaining the OLSR protocol’s reliability, the research presented in this paper proposed an improved OCI-OLSR (Optimized Control Interval-Optimized Link State Routing) that focuses on better control interval management, an advanced MPR selection process, reducing neighbor hold time as well as decreasing flooding. The suggested proposed protocol was examined using the NS3 simulator, and it was compared to the standard OLSR version and AODV(Ad-hoc On-Demand Routing) routing protocol. According to the analysis’s findings, the suggested system has a lot of promise in terms of a variety of performance metrics under diverse conditions. Overall, the article makes the case that the OCI-OLSR protocol may enhance the performance of the regular OLSR protocol in wireless ad hoc networks by addressing a number of the protocol’s flaws.

Estimation of the Achievable Performance of Mobile Ad Hoc Networks with Optimal Link State Routing

“…In spite of the development of new routing protocols, many research works aimed at improving OLSR continue to appear. For example, an improved OCI-OLSR protocol (Optimized-Control-Interval-Optimized-Link-State-Routing) is proposed in [30], which focuses on better control interval management, enhanced MPR process selection, reducing neighbor hold time, and decreasing flooding. In [31], the multipath heterogenous ad hoc network OLSR (MHAR-OLSR) protocol is described and investigated.…”

“…Once again, we note that for networks in which the change in node position is quite slow (no faster than the average packet transmission time from source to destination) in most cases, the OLSR protocol or its modifications are used. Thus, in [30], the number of research papers with the keywords "OLSR" and "MANET" is given. This paper studies the research trends of the OLSR routing protocol in MANETs and analyzes numerous advantages of OLSR (low packet delay, ability to work in high-density networks, much higher performance compared to other protocols, etc.).…”

“…This paper studies the research trends of the OLSR routing protocol in MANETs and analyzes numerous advantages of OLSR (low packet delay, ability to work in high-density networks, much higher performance compared to other protocols, etc.). It has been shown that in the time period from 2002 to 2022, the number of research papers on the use of OLSR in MANETs is steadily increasing [30]. Therefore, in this paper, OLSR is selected as the routing protocol for the study.…”
