Non-interfering Multipath Mechanism for Media Stream Transmission in Wireless Sensor Networks

摘要

Potential applications of multimedia sensor networks cover a wide spectrum from military to industrial and from commercial to environmental monitoring. These applications require high bandwidth and are extremely delay sensitive. However, multipath routing is one of the appropriate solutions for multimedia data transmission, unlike traditional schemes using the shortest paths. Therefore, in this paper, we address the issue of interference in WMSNs and present an non-interfering multipath mechanism, integrated in our previous GMFT routing protocol. The proposed mechanism intervenes during path exploration phase in order to limit adjacent paths interactions. Simulations results show a significant contribution and indicate that the proposed mechanism provides a higher data packets delivery rate.
