Otimização de rede de sensores sem fio através de algoritmo de codificação de rede

A wireless sensor network is a kind of ad hoc network that can be used to monitor a variety of environmental characteristics in various fields with, for instance, military purposes, environmental purposes, etc. A typical problem of these networks is how to collect and send historical information from all network sensor nodes to the base station. In this work are compared two techniques using network coding to reduce the total number of transmissions in sensor networks and the transmission time, resulting in a more efficient network. Two network coding configurations are implemented and the results are compared to those of a network that uses a simple broadcast transmission.
