Análise de protocolos de roteamento Unicast em redes Ad Hoc móveis baseada em um modelo realístico de bateria.

Abstract

Mobile Ad hoc Networks (MANETs) are characterized by their devices to operate without presence of any centralized control. Most unicast routing protocols for mobile ad hoc networks were evaluated through simulation. However, most network simulators adopt a linear battery model, which produces incorrect results, because it does not take into account the battery capacity recovery effect. This work aims to re-evaluate three representative unicast routing protocols (i.e., AODV, DSR and OLSR) based on the more realistic Rakhmatov-Vrudhula battery model; thus, providing us a better insight into these protocols performance. We used the Network Simulator (NS-2). The scenarios simulation were configured by varying traffic patterns and mobility. The metrics of energy consumption, network lifetime, number of alive nodes, packet delivery fraction, normalized routing load and average delay end to end were used in the evaluation of protocols. The results show energy consumption minor and that the protocols’ lifetime and packet delivery rate increase significantly when simulations are based on the Rakhmatov-Vrudhula battery model.
