Large Data Transport for Real-Time Services in Sensor Networks

There are several surveillance and reconnaissance applications of sensor networks (such as military), which require timely and efficient detection of an event (i.e., enemy troops and vehicles). Moreover, the information gathered is then transferred reliably to a sink, located at a remote control station. Incorporation of multimedia data (e.g., image) certainly enhances the functionality and applicability of such applications. However, since image transfer is often characterized by generation of large amount of data efficient fragmentation is necessary. Furthermore, it demands real-time delivery of data over a multi-hop network. In this paper, we propose an efficient routing scheme that provides real-time transfer of large amount of data. The experimental results show that our scheme results in reducing data loss rate while obtaining recognizable image information.
