# Orchestra
|
||||||
|
|
||||||
|
## Overview
|
||||||
|
|
||||||
|
Orchestra is an autonomous scheduling solution for TSCH, where nodes maintain
|
||||||
|
their own schedule solely based on their local RPL state. There is no centralized
|
||||||
|
scheduler nor negociatoin with neighbors, i.e. no traffic overhead. The default
|
||||||
|
Orchestra rules can be used out-of-box in any RPL network, reducing contention
|
||||||
|
to a low level. Orchestra is described and evaluated in
|
||||||
|
[*Orchestra: Robust Mesh Networks Through Autonomously Scheduled TSCH*](http://www.simonduquennoy.net/papers/duquennoy15orchestra.pdf), ACM SenSys'15.
|
||||||
|
|
||||||
|
## Requirements
|
||||||
|
|
||||||
|
Orchestra requires a system running TSCH and RPL.
|
||||||
|
For sender-based unicast slots (`ORCHESTRA_UNICAST_SENDER_BASED`), it requires
|
||||||
|
RPL with downwards routing enabled (relies on DAO).
|
||||||
|
|
||||||
|
## Getting Started
|
||||||
|
|
||||||
|
To use Orchestra, add a couple global definitions, e.g in your `project-conf.h` file.
|
||||||
|
|
||||||
|
Disable 6TiSCH minimal schedule:
|
||||||
|
|
||||||
|
`#define TSCH_SCHEDULE_CONF_WITH_6TISCH_MINIMAL 0`
|
||||||
|
|
||||||
|
Enable TSCH link selector (allows Orchestra to assign TSCH links to outgoing packets):
|
||||||
|
|
||||||
|
`#define TSCH_CONF_WITH_LINK_SELECTOR 1`
|
||||||
|
|
||||||
|
Set up the following callbacks:
|
||||||
|
|
||||||
|
```
|
||||||
|
#define TSCH_CALLBACK_NEW_TIME_SOURCE orchestra_callback_new_time_source
|
||||||
|
#define TSCH_CALLBACK_PACKET_READY orchestra_callback_packet_ready
|
||||||
|
#define NETSTACK_CONF_ROUTING_NEIGHBOR_ADDED_CALLBACK orchestra_callback_child_added
|
||||||
|
#define NETSTACK_CONF_ROUTING_NEIGHBOR_REMOVED_CALLBACK orchestra_callback_child_removed
|
||||||
|
```
|
||||||
|
|
||||||
|
To use Orchestra, fist add it to your makefile `APPS` with `APPS += orchestra`.
|
||||||
|
|
||||||
|
Finally:
|
||||||
|
* add Orchestra to your makefile `APPS` with `APPS += orchestra`;
|
||||||
|
* start Orchestra by calling `orchestra_init()` from your application, after
|
||||||
|
including `#include "orchestra.h"`.
|
||||||
|
|
||||||
|
## Configuration
|
||||||
|
|
||||||
|
Orchestra comes with a number of pre-installed rules, `orchestra-rule-*.c`.
|
||||||
|
You can define your own by using any of these as a template.
|
||||||
|
A default Orchestra configuration is described in `orchestra-conf.h`, define your own
|
||||||
|
`ORCHESTRA_CONF_*` macros to override modify the rule set and change rules configuration.
