Fault-Tolerant Manycast to Mobile Destinations in Sensor Networks

Manycast is a group communication primitive wherein the source is required to send data packets to a certain number of a given set of destinations. In this article, we design fault-tolerant protocols for manycast operations in sensor networks with mobile destinations. To develop efficient protocols, we propose a location management scheme, which manages information about the locations of mobile destinations in a distributed manner. Based upon that, we develop rectangle-based and GridTree-based fault-tolerant manycast routing protocols. Simulation results show that GridTree approach achieves sufficiently high success ratio, while using minimal transmission cost.
