WS-OLSR: Multipoint Relay Selection in VANET Networks using a Wingsuit Flying Search Algorithm

Abstract

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.

“…The current traditional MPR selection algorithm is proposed in the standard OLSR protocol. This is a wingsuit flying search algorithm [4], which designs an MPR set that can ensure that a node can reach all strictly symmetrical two-hop neighbour nodes through the MPR node relay whose willingness is not willing_ never. The algorithm flow is shown in Figure 1.…”

“…To transmit vital information including traffic conditions, safety alerts, and real-time navigation data, vehicles in VANETs communicate with one another and with roadside infrastructure. Numerous routing methods have been suggested to enable effective data dissemination in VANETs, with the Wingsuit Search-based Optimised Link State Routing Protocol (WS-OLSR) emerging as a popular option due to its scalability and adaptability to highly dynamic vehicular environments [4].…”

“…Additionally, the researchers have made several excellent attempts to select MPRs in order to improve the performance of the OLSR protocol while taking packet delivery ratio, routing overhead, throughput [24][25][26], energy efficiency [27], security issues [28] etc. into account.…”
