Abstract The dynamic formations of the mobile ad hoc networks require routing protocols to handle the routing requirements in runtime. The purpose of this work is to improve the endurance, quality, and trust of the path chosen by the link state routing in mobile ad hoc networks. The multipoint relay concept has been fascinating in link sate routing optimization to reduce duplicate retransmissions in the same region. In this paper, we present the notion of flexibility and suitability in choosing the multipoint relays. A suitable multipoint relay selection algorithm has been proposed to choose the appropriate multipoint relays which are trustworthy, restrain appropriate residual battery and possess a good quality link for interconnections. The algorithm also takes care of the willingness, reachability, degree, and the relative mobility of the nodes in the selection process. The results illustrate that the selection of the appropriate relay nodes offers substantial improvements.

1 Introduction Mobile ad hoc networks offer quick and dynamic formation of the network of the nodes having moving competency and wireless capability without requiring the central administration. These autonomous and self-organized networks have been useful for information exchange in emergency situations. The quick formation of the self-configuring, selforganized, multi-hop network reflects the usability aspect of these networks (Conti and Giordano 2014). The infrastructure-less nature, non-discrimination of host and routers, and possible extendibility to the backbone networks make these networks a striking choice for widespread applications (Harrag et al. 2019). Routing is the key mechanism of multi-hop ad hoc networks, and routing protocols play an important role in the route finding process (Karthikeyan et al. 2020). The proactive calculation of the routes and on-demand route

discovery are the two classic route finding approaches. The on-demand route discovery assists in reducing the routing overhead (Saini et al. 2020), while the proactive approach formulates the routes in advance that assist in overcoming the delay incurred in the route discovery process. The prior information of the routes of the networks with periodic maintenance makes the proactive approach more deterministic even under the dynamism of the ad hoc network (Murthy and Manoj 2013). Optimized link state routing (OLSR) is a promising proactive routing protocol. The protocol uses the technique of multipoint relay
