IoTSim-Edge

IoTSim-Edge simulator provides the following features to simulate the IoT and edge environment.

  1. Variety of IoT devices need to be combined with edge IoT gateways  to satisfy the requirements of an application
  2. Modeling networking graph between diverse type of IoT and edge computing device in an abstract manner can be very challenging
  3. Modeling data and control flow dependencies between IoT and Edge layers to support diverse data analysis work-flow structure is non-trivial
  4. Capacity planning across edge computing layer is challenging as it depends on various configuration parameters including data volume, data velocity, upstream/downstream network bandwidth, to name a few
  5. The communication between IoT and edge devices is very different from cloud datacenter communication, which is generally based on wired and/or wireless protocol.
  6. The energy model of sensor nodes
  7. Modeling the mobility pattern of devices dynamicity of IoT environment

IoTSim-Edge simulator also models the distribution and processing of streaming data generated by IoT devices in the Edge computing environment.

IoT_Edge

Above figure describes The IoTSim-Edge sytstem model. To better describe the management of computing, the computing environments are divided into two main  layer 1 (L1), edge systems and microdata centers; and layer 2 (L2), IoT devices. The IoTSim-Edge also supports of modelling of data  analysis tasks as MicroElements (MELs) – a fundamentaly new graph-based abstraction to model and program IoT applications.

Unique Features

  • New IoT application graph modeling abstraction that allows practitioners to define the data analytic operations and their mapping to different parts of the infrastructure (e.g. IoT and edge).
  • The abstraction that supports modeling of heterogeneous IoT protocols along with their energy consumption profile.
  • It allows practitioners to define the configuration of edge and IoT devices along with the specific protocols they support for networking.
  • The abstraction that supports modeling of mobile IoT devices.
  • It also captures the effect of handoff caused by the movement of IoT devices. This supports a cooperative edge-to-edge communication that allows the transfer of the processed data of the respective IoT device by one edge via another edge.

IoTSim-Stream

IoTSim-Stream is an IoT Simulator for Stream processing on the big data that offers an environment to model complex stream graph applications in Multicloud environment, where the large-scale simulation-based studies can be conducted to evaluate and analyze these applications. It leverages the features of CloudSim and integrating real-time processing model with workflow scheduling and execution to execute the modeled stream graph application in Multicloud environment.

IoTSim-Stream supports the modelling of different patterns/structures of stream workflow applications, which are linear (a multi-stage application where each stage processes input stream generated by the previous stage and produces the output stream to the following stage), branching (an application with limited precedence constraints that splits data stream to perform different parallel processing and then combining the results for further analysing) and hybrid (a mix of linear and branching patterns).

Above figure shows simple instance of large-scale datastream-processing service that an be simulated and modelled using IoTSim-Stream. The example service consists of Apache Kafka (data ingestion layer), Apache Storm (data analytics layer), and  Apache Cassandra Systems (data storage layer).

Unique Features

  • Support modeling data incentive IoT-based applications using stream processing model (aka stream graph applications).
  • Support modeling Multicloud environment as an execution environment for stream graph application.
  • Support user-defined resource provisioning and scheduling policies.
