Abstract

Shadow zone and delay aware routing (SZODAR) scheme is a practical and distributed protocol that can find routes around shadow zones. In SZODAR, sensor nodes can raise or lower their acoustic transceivers to a depth such that shadow zones of the neighboring nodes are avoided. This paper presents the protocol working principle and preliminary calculations of the engineering parameters.
