“…The primary objective of routing protocols like OLSR is to establish and maintain efficient data paths between nodes in a network. OLSR achieves this by proactively exchanging topology information among neighbouring nodes, which allows each node to build a routing table based on the most up-to-date network state [17] [18], [19]. However, while OLSR exhibits many desirable characteristics, it is not without its challenges and limitations.…”

Vehicular AdHoc networks (VANETs) allow connectivity in dispersed vehicle environments and in other areas of difficult access, where conventional network systems are not satisfactory. One of the most significant technical challenges faced in implementing VANET is to design an efficient routing protocol able to provide a reliable path between the source and destination of the information. This paper discusses a routing scheme that incorporates the control strategy for transmitting messages and Global Navigation Satellite System (GGNS) information to optimise network routing. This scheme uses geolocation information to select the best path to forward the messages. To simulate a communication in real-life scenario, we used the Simulation of Urban MObility (SUMO) and Network Simulator-version 3 (NS-3) platform to compare our proposed algorithm to the traditional routing protocols in scenarios where the number of nodes as well as the number of source-destination pairs vary. Our results show that the proposed NAV2V algorithm can decrease the packet loss rate, end-to-end delay, and enhance network efficiency.

The routing protocol is considered the backbone of network communication. However, mobility and bandwidth availability make optimizing broadcast message flooding a problem in an Optimized Link State Routing (OLSR)-based mobile wireless network. The selection of Multi-Point Relays (MPRs) has lately been proposed as a potential approach that has the added benefit of eliminating duplicate re-transmissions in VANET networks. Wingsuit Flying Search (WFS) is one of the swarm intelligent metaheuristic algorithms, it enables one to find the minimum number of MPR. In this study, a novel methodology based on (WFS) is called WS-OLSR (Wingsuit Search-OLSR). The (WS-OLSR) is investigated to enhance the existing MPR-based solution, arguing that considering a cost function as a further decision measure will effectively compute minimum MPR nodes that give the maximum coverage area possible. The enhanced MPR selection powered by (WFS) algorithm leads to decreasing MPR count required to cover 95% of mobile nodes, increasing throughput , and decreasing topology control which mitigates broadcasting storm phenomenon in VANETs.
