Um Protocolo de Roteamento Sensível ao Tempo para Redes de Sensores Sem Fio

Abstract

Advances and researches in Wireless Sensor Networks (WSN) allowed their use for several purposes. Unmanned space missions, interplanetary and underwater explorations are examples of critical and dangerous environments that benefit with their use. Applications in these environments share the need for operation without human intervention, by being inaccessible or dynamical environments. Besides physical limitations, using WSN as source of data in challenging environments requires the ability to real-time monitoring, considering its unpredictability of mobility and amount of nodes. In this paper we propose PROST, a time-aware routing protocol to enable WSN for realtime monitoring of challenging environments.
