Resumo-Diversos protocolos de redes de comunicação são inspirados na natureza, por exemplo, em insetos sociais (formigas, abelhas, vaga-lumes, entre outros). Muitas espécies de fungos formam redes de hifas capazes de auto-organização, resiliência e eficiência na construção de redes de transporte de nutrientes. Isso inspira comparar o fenótipo fúngico a uma rede de comunicação. Nessa perspectiva, este artigo propõe um protocolo de roteamento para MANETs baseado no comportamento de fungos chamado de HyphaNet. O HyphaNet é do tipo reativo e multipath. Simulações no NS-2.35 mostram bom desempenho comparado ao AODV clássico e ao SARA baseado em formigas.

“…Obviously, it is not possible for a network to achieve the best results for all KPIs, since many of them have opposite requirements. KPIs of a network must be realistic and the network should have acceptable results in all KPIs [51]. Currently, the collection of the simulation data in NS-3 can be realized using several methods.…”

During the last decade, the number of vehicles on roads has been rapidly growing. Therefore, the demands for communication on the move are also increasing and the attention from many researchers is focused on the Vehicular Ad hoc NETworks (VANETs) because of their importance for Intelligent Transportation Systems (ITSs). Due to the complexity and cost of practical evaluation of VANETs, the researchers often rely on network simulation in order to evaluate their work. In this paper, we have developed a Network Simulator 3 (NS-3) based framework for VANETs that provides network performance analysis based on the key performance indicators such as throughput, packet loss ratio, overhead, end-to-end delay, jitter, etc. Since VANETs are highly dynamic networks, many researchers have proposed different routing protocols in order to improve the network performance. In this paper we have compared several topology-based routing protocols, and proposed utilization of the commonly used Expected Transmission Count (ETX) metric to improve VANET performance.

“…Two traffic generation strategies were considered, both using On/Off sources with constant bit rate (CBR) and UDP protocol. In the first strategy a traffic similar to that used in [47] was considered. In this case, during the whole simulation, each node will be sending data to a random destination for a time chosen between 40 and 60 seconds.…”

Vehicular Ad Hoc Networks (VANETs) are self-configuring networks where the nodes are vehicles equipped with wireless communication technologies. In such networks, limitation of signal coverage and fast topology changes impose difficulties to the proper functioning of the routing protocols. Traditional Mobile Ad Hoc Networks (MANET) routing protocols lose their performance, when communicating between vehicles, compromising information exchange. Obviously, most applications critically rely on routing protocols. Thus, in this work, we propose a methodology for investigating the performance of well-established protocols for MANETs in the VANET arena and, at the same time, we introduce a routing protocol, called Genetic Network Protocol (G-NET). It is based in part on Dynamic Source Routing Protocol (DSR) and on the use of Genetic Algorithms (GAs) for maintenance and route optimization. As G-NET update routes periodically, this work investigates its performance compared to DSR and Ad Hoc on demand Distance Vector (AODV). For more realistic simulation of vehicle movement in urban environments, an analysis was performed by using the VanetMobiSim mobility generator and the Network Simulator (NS-3). Experiments were conducted with different number of vehicles and the results show that, despite the increased routing overhead with respect to DSR, G-NET is better than AODV and provides comparable data delivery rate to the other protocols in the analyzed scenarios.
