Um Protocolo de Roteamento Multitabelas para Monitoramento de Sinais Vitais em Cenários de Operações Militares

Abstract

Mobile Ad-Hoc NETworks (MANETs) benefit applications in military scenarios by enabling the monitoring of military’s vital signs in battlefileds, and thus increase the mission’s chance of success by assisting the decision-making process. Intermittent communication and route volatility make data transmission challenging in MANETs. Frequent disconnections and consequent failures lead to significant delays and errors in message delivery. This work aims to expand the availability of paths during the communication of nodes running an application in a mobile ad-hoc netwokr. We propose MT-AODV, a reactive routing protocol that evolves the AODV protocol, widely used in the literature. MT-AODV adds the ability to manage multiple routes, aiming to increase communication performance in military operations scenarios with troop mobility. MT-AODV calculates multiple routes to find multiple possible paths in the network to provide greater resiliency and lower latency in communication. The performance of MT-AODV is compared to other traditional MANET protocols, through simulation in different scenarios, with node mobility and node failure. The results show that the proposed protocol presents better performance compared to the original AODV protocol due to the increased availability of routes through new tables.
