Application Aware Overlay One-to-Many Data Dissemination Protocol for High-Bandwidth Sensor Actuator Networks

An application-aware deterministic overlay one-to-many (DOOM) protocol is proposed for meeting heterogeneous QoS requirements of multiple end users of high-bandwidth sensor actuator network (HB-SAN) applications. Although DOOM is initially targeted for use in collaborative adaptive systems of weather radars, it has been designed for use in wider class of sensing systems. DOOM protocol performs rate-based application aware congestion control by selecting end user specific subset of the sensor data for transmission thus adapting to available network infrastructure under dynamic network conditions. Performance of DOOM is evaluated for radar networking using a combination of Planetlab as well as an emulation based test-bed. It is shown that DOOM protocol is able to meet individual end user QoS requirements as well as aggregate QoS requirements of different end users. Moreover, multiple DOOM streams are friendly to each other as well as to TCP cross- traffic sharing the bottleneck link
