Data Dissemination With Ring-Based Index for Wireless Sensor Networks
Overview In wireless sensor networks, sensor nodes are capable of not only measuring real world phenomena, but also storing, processing, and transferring these measurements. Many techniques have been proposed for disseminating sensing data. However, most of them are not efficient in the scenarios where a huge amount of sensing data are generated, but only a small portion of them are queried. This paper first proposes an index-based data dissemination scheme to address the problem. With this scheme, sensing data are collected, processed, and stored at the nodes close to the detecting nodes, and the location information of these storing nodes is pushed to some index nodes, which act as the rendezvous points for sinks and sources.
