Broker-Messaging Communication Sample Clauses

Broker-Messaging Communication. There are many solutions that offer communication in distributed systems. The shortcomings of the alternatives are combinations of coupling of space (i.e. sender and receiver need to hold references about each other), time (i.e. the components need to interact at the same time) and synchronisation (i.e. the individual components block their activity while waiting for other processes to finish). To solve these issues we use a publish/subscribe mechanism, which decouples time, space and synchronisation. Furthermore the message delivery logic lies with the message broker, decoupling it from the application layer. In particular we are using RabbitMQ15 as a message broker. I natively support the Advanced Message Queuing Protocol (AMQP), which has been introduced in (Xxxxxxx, 2006) as an open standard for message oriented middleware. The protocol adds another advantage to the table by further dividing the message brokering task into exchanges and message queues, whereby the exchange decides which messages will be pushed into which queue. Furthermore the message broker supports the use of Message Queuing Telemetry Transport (MQTT) (Xxx Xxxxxxxx, 2008), a lightweight publish/subscribe protocol designed specifically for Wireless Sensor Networks(WSN) This leads to enhanced flexibility for developers and avoids the need for static implementations. In order to handle scalability issues, which arise in the context of IoT and Smart City data, we propose aggregating the data before passing it through the middleware. In (Xxxxxxx Xxxx, 2014) we examine how these data abstractions can help to reduce data traffic and ultimately even energy consumption on the sensory level. 15 xxxx://xxx.xxxxxxxx.xxx/ The messages in our system have three fields. The first field is called ”message types”: it defines the type of message. The second field is called “metadata”: it contains location and time information as well as information about the data source. The third field is called ”data”: it consists of the raw values and identifier. We have defined three types of messages: transform, store and forward. Generally the messages include all the three types. In our case, the subscriber will initially perform some computations on the data, store it for later evaluations and then publish the transformed data. This approach allows different components to work asynchronously on stream data. Apache Thrift Apache Thrift allows for cross-language development of software components, by providing a ...
