Only used in conjunction with UEs running instances of the MultihopD2D application. It collects statistics related to notification messages broadcast by the MultihopD2D applications by gathering data through method calls from these applications.

Each time a MultihopD2D application generates a new message (upon notification by the EventGenerator module), a new event is registered via the recordNewBroadcast() function. Each event is tied to a *target area*, which represents a defined set of nodes intended to receive the notification of the event. The receiving nodes report the event back to this module in order to update the statistics related to that event. For instance, upon receiving a message, the node will call the recordReception() function to record the 'reception' event.

Used in

Name	Type	Description
MultiCell_D2DMultihop	network	Five eNodeB cells, each reaching the EPC PgwStandard through a router of its own, with a further router and a server behind the core. There are no X2 links. numUe1 to numUe5 LteUe terminals attach per cell, and an EventGenerator and a MultihopD2DStatistics module sit beside them, wired to nothing.
