Effectively transmit real continuous media stream in WMSNs, while ensuring its reliability to deal with various constraints, remains a serious problem, especially for critical and energy-intensive applications. Given the very low number of routing protocols that have approached the experimental phase and still less those who have tackled the issue related to fault tolerance during data transmission. In this paper, we evaluate experimentally on a real testbed the continuous media stream by introducing two fault-tolerant mechanisms implemented in the Geographic Multipath Fault Tolerant (GMFT) routing protocol over the Imote2 platform. We jointly consider sudden failures and those caused by total battery exhaustion during massive data transmission. Experimental results show promising performances, that outperform experimental existing solutions in terms of reliability for continuous media stream with distributed energy consumption which ensures a good load balancing in the network and extends positively its lifetime.
