Data Aggregation Mechanism Using Dynamic Routing With Cyber Physical Systems

摘要

In wireless sensors the data can be send through network without any data collusions. Here, we are transmitting the data in the form of encrypted packets through network to destination without any misplacement of data packets. To fulfilling that, data aggregation is used. Data aggregation has been widely recognized as an efficient method to reduce energy consumption in wireless sensor networks, which can support a wide range of applications such as monitoring temperature, humidity, level, speed etc. The data sampled by the same kind of sensors have much redundancy since the sensor nodes are usually quite dense in wireless sensor networks. To make data aggregation more efficient, the packets with the same attribute, defined as the identifier of different data sampled by different sensors such as temperature sensors, humidity sensors, etc., should be gathered together. However, to recognize that the present data aggregation mechanisms did not take packet attribute into consideration. In this paper, we take the lead in introducing packet attribute into data aggregation and propose an Data Aggregation mechanism using Dynamic Routing (DADR) which can make packets with the same attribute convergent as much as possible and therefore improve the efficiency of data aggregation.
