Wireless sensor networks represent an extremely fastgrowing emerging technology, but still suffer from several limitations. The state of the art in sensor networks focuses on optimizing the existing protocols to address the two main challenges affecting the sensors: failures and energy consumption. Our contributions in this paper include: analyzing most relevant protocols that attempt to address these two problems, presenting methods to achieve local reconstruction for a sensor network that uses multi-path routing and proposing a new protocol, called LSynD, an extension of the Tributaries and Deltas approach. LSynD achieves a faster, more localized and energy efficient reconstruction than its predecessor protocols by creating multiple adaptive multi-path routing regions.
