Abstract

The Mobile Ad-Hoc Networks (MANETs) benefit applications in military scenarios, as they enable the monitoring of soldiers' vital signals in field operations. Intermittent communication and route volatility make data transmission in MANETs challenging. Frequent disconnections and consequent failures generate significant delays and message delivery errors. We propose the Multi-Table Ad-Hoc On-Demand Distance Vector (MT-AODV) protocol, an optimization of the AODV routing protocol, to improve communication performance in military operations scenarios with troop mobility. MT-AODV calculates multiple routing tables to find multiple possible paths aiming to provide greater resilience and less latency communication. The MT-AODV performance evaluation was compared to other traditional MANET routing protocols, in a variety of simulated scenarios, with node failure and mobility. The results show that MT-AODV perform better to the original protocol due to the increased availability of paths in its route tables.
