“…Results demonstrate the efficiency of the method in assuring load balance at gateways and the routing paths. In Reference 21, two methods were presented to diminish the multi point relay (MPR) execution number in a way to minimize control message congestion in OLSR. Results revealed the accuracy of the proposed method in rising both packet delivery and throughput while decreasing the communication overhead.…”

Recently, with the different issues encountered in road mobility, the presence and development of the Vehicular Ad hoc Networks (VANETs) have become a necessity. VANETs have various positive impacts on vehicular safety, road security, traffic management, drivers' comfort, and passengers' convenience. However, the expansion in the world's population has led to enormous traffic congestion on multiple roads. This congestion results in uncontrollable delays affecting economics, society and the environment. In this paper, we propose two routing protocols that depend on the Signal to Interference Ratio (SIR), differing from existing ones by introducing a new metric to select the best route from a source to a destination. In the first protocol, we choose the best route based on the maximum level of SIR at each node. Besides, we select the Backup SIR to minimize the number of SIR calculations at the channel update process. While in the second protocol, we design a hybrid Markov chain model composed of two Markov models; the first one aims at predicting the SIR value of the next round, while the second one is an analytical model that targets managing the number of channel update process. In order to validate our solution, extensive simulations are realized in considering the real scenario of the city of Beirut (Lebanon). The results show that our proposed protocols perform better with regard to overhead, packet delivery ratio, throughput and end‐to‐end delay.

“…The RREQ packet contains the source address, a destination address, hop count, broadcast id and sequence number. While, the RREP packet contains the source address, a destination address, destination sequence, hop count and lifetime.Vehicular Reactive Protocol (VRR), and Stable CDS-Based Routing Protocol (SCRP) is examples of Reactive Routing Protocols [13], [17], [18].…”

The vehicular communication hasbeen considered as the most promising wirelesscommunication technology in the computernetwork scenario, the beginning of which hasmarked a great change for the passengers in therange of safety application. The development ofvehicular communication increased securitythreats and weaknesses. Vehicularcommunication is exposed to severalvulnerabilities such as Denial of Service attacks(DoS), Black hole and fabrication attacks.Fabrication attack consists of a malicious nodethat modifies information in the packet causingcritical damage in the network like congestionand high delay. In this paper, we propose a novelfabrication model which consists of twoalgorithms one for source attack and another foranti-source attack. In such attack, the maliciousnode fabricates the source address of the routerequest message; this means that the maliciousnode selects randomly from the routing table asource address that is different from the inputsource address and the source address of thecurrent node and forwards the message to itsneighbors. In the anti-attack, our novel proposedalgorithm has the role to identify the sourceattack during the communication. We create twovariables at each node in order to check if theinput source address in RREQ is equal to theoutput source address in RREQ; otherwise, thenode is identified as a malicious node and anurgent message is broadcasted to all nodes toremove it from their routing table. The proposedalgorithm targets to minimize the delay ofpackets. Our simulation is done using SUMO0.22 simulator, NS-2.35 and awk scripts; thesimulation was applied on Hamra area (Beirut,Lebanon). The results show good improvementsin terms of packet delivery ratio and the end toend delay.
