Avaliação de Mecanismos de Segurança em uma Plataforma para Redes de Sensores Sem Fio

Germano GuimarãesEduardo SoutoJudith KelnerDjamel Sadok

Wireless sensor networks have recently emerged as successful technologies in a number of applications. The need to build security services into them remains however a considerable challenge as the hardware used still shows serious processing and energy limitations. This work evaluates the impact of a number of security mechanisms on sensor nodes and the network as a whole. Hence a number of measurements were undertaken in a real sensor platform in order to establish accurately energy consumption for various encryption algorithms as well when none of these are used. To our knowledge this is an innovative piece of work that shows through both simulation and measurements that encryption algorithms have different impacts on throughput, delay as well as energy consumption.
