this protocol proposes a energy efficient multipath data transfer scheme in wireless sensor networks to address the troubles caused by false data injection attack. This can be done by early detection and filtering of injected false data.

Direct sequence spread spectrum (DSSS) communication systems has been widely used in these years for its advantage of wide spectrum, low working Signal-to-Noise ratio (SNR), anti-interference, anti-multipath effect and capability of LPI and LPD.

In this paper, we investigate the problem of reliable detection and localization of active sound source using a new fusion approach of the vision and the acoustic data that enables reducing errors of acoustic localization caused mainly by syn
