Use of Data Replication in WSNs Directed to Special Needs

摘要

In the last decade, there has been a major technological breakthrough in the areas of sensors, integrated circuits and wireless communication, which led to the creation of networks of wireless sensors. This type of network can be used in monitoring, tracking and processing in different contexts. To maintain the freshness of the data between these devices and more specifically between heterogeneous devices, an alternative is to use a technique called Data Replication. This technique used in the database is SGBDD or System Manager Distributed Database. This work focuses primarily present an evaluation of the feasibility of replication of database network wireless sensor (WSNs), sensors using SunSPOT as a setting will be used in patients with special needs (deaf and dumb) in hospital settings.
