Simulation of Bluetooth, including Bluetooth Low Energy and Bluetooth Mesh, for Evaluating Interoperability with WLAN.


Bluetooth Low Energy (BLE), which was introduced as part of the Bluetooth 4.0 specification, is a short-range wireless communication technology aiming at low-cost and low-power communication. The BLE protocol stack consists of a controller which includes physical and link layer, and a host which includes Logical Link Control and Adaptation Protocol (L2CAP), Attribute Protocol (ATT), Security Manager Protocol (SMP), Generic Attribute Profile (GATT) and Generic Access Profile (GAP). Since professional BLE simulators are unavailable, the task was to develop the BLE stack on an open source simulator NS-3, a discrete-event modular network simulator. The BLE stack module (written in C++) was extended with a Mesh protocol and the interoperability with WLAN was analysed.
