Data Dissemination in Mobile Phone Sensor Networks [Extended Abstract]

Deploying sensors over large areas is costly in terms of con-figuration, hardware, and maintenance. Using onboard sen-sors of today mobile phones can significantly reduce the expenses in monitoring areas and disseminating events or data. Via the available short-range Bluetooth and/or WiFi interfaces, measured data are not only gradually delivered, but also possibly more reliable. In our simulation, existing Delay-Tolerant Network routing algorithms show poor per-formance on a complex network comprising diverse kinds of sensor nodes, such as, mobile phones, cars, and road side units. New approaches that can perform well on such het-erogeneous networks are needed. They also need to support exchanging measurements among sensors for more accurate inference. In the early phase, we set up a heterogeneous architecture composed of different sorts of sensors, and pro-pose an algorithm, Unified routing, for routing and dissem-inating. A further variant of the scheme is being developed. Early simulation results are consistent with theoretical pre-diction. After finishing the first step, Unified routing, the focus of our research will be on distributed data process-ing. Finally, routing and distributed data processing will be investigated in a testbed in a realistic context
