+# Roadmap     {#roadmap}
+
+The aim of the roadmap is to identify priority areas of RIOT development & enhancements.
+For each area, some near-future plans and concrete next steps are indicated.
+The text and items below are tentative, up for discussion, to be updated by regular pull requests.
+
+
+# Network Stack High layers
+(contact/steering: [Martine](https://github.com/miri64))
+
+1. ICN stack support clean-up
+2. discuss mid- and long-term plans for network stack maintenance & development (GNRC vs other supported stacks)
+3. Support for CoAP blockwise transfer, observe. Also see [Ken's](https://github.com/kb2ma) unofficial [CoAP for RIOT](https://github.com/kb2ma/RIOT/wiki/CoAP-Home) page.
+4. revisit network time synchronization
+
+
+
+# Network Stack Low layers
+(contact/steering: [Peter](https://github.com/PeterKietzmann))
+
+1. Towards fully open source support of 6LoWPAN over BLE
+2. Re-integrate and clean-up 802.15.4 TSCH integration
+3. Retransmissions by MAC: finalize and merge `netdev_retrans`
+4. Point-to-Point Protocol (PPP): finalize and merge `gnrc_ppp`
+
+
+
+# Power Modes
+(contact/steering: [Hauke](https://github.com/haukepetersen))
+
+1. ~~RFC from \@gebart for arbitrary freq for xtimer~~ done
+2. ~~prototype LPM concept from Kaspar, demoed on PLACE-HOLDER hardware. Basic idea is to define unified/simplified layered LP modes that apply to 99% of IoT hardware. More optimized board-specific LPM would~~ prototype done
+3. implement PM interface for existing platforms (-> https://github.com/RIOT-OS/RIOT/issues/6802)
+4. xtimer use of RTT low-power timer
+5. concept to fix shell usage issue while LPM activated
+6. integrate generic power management functions in device driver APIs (netdev, SAUL, ...)
+7. more advanced LPM concepts:
+  - potentially get rid of idle thread
+  - sleeping for short periods (in cases where it is not feasible to switch to the idle thread and back) -> mitigate active waiting
+
+
+
+# Peripheral drivers
+(contact/steering: [Hauke](https://github.com/haukepetersen))
+
+1. remodeling  of the `periph/i2c.h` interface and subsequent adaption/rewrite of all existing implementations (-> https://github.com/RIOT-OS/RIOT/issues/6577)
+2. cleanup and unification of low-level timer interfaces (`timer`, `rtt`, `rtc`)
+3. introduction of `spi_slave` interface
+4. introduction of `i2c_slave` interface
+
+
+
+# Software Updates
+(contact/steering: [Emmanuel](https://github.com/emmanuelsearch))
+
+1. ~~Basic bootloader, flashing and booting one of multiple firmware slots~~ done, see [riotboot](https://github.com/RIOT-OS/RIOT/tree/master/bootloaders/riotboot)
+2. ~~Secure firmware update over CoAP compliant with SUIT draft spec [draft-ietf-suit-manifest-03](https://tools.ietf.org/html/draft-ietf-suit-manifest-03)~~ done, see [SUIT update example](https://github.com/RIOT-OS/RIOT/tree/master/examples/suit_update)
+3. Update SUIT spec support to comply with [draft-ietf-suit-manifest-04](https://tools.ietf.org/html/draft-ietf-suit-manifest-04)
+4. Modularize to provide toolbox supporting other image storing (e.g. support external flash), transport (other than CoAP), crypto (e.g. secure element).
+5. riotboot support for architectures other than Cortex-M
+
+
+
+# Documentation
+(contact/steering: [Emmanuel](https://github.com/emmanuelsearch))
+
+1. ~~publish roadmap~~ done
+2. ~~Introduce RIOT Developer Memos~~ done, see [RDM0](https://github.com/RIOT-OS/RIOT/tree/master/doc/memos)
+3. Write and publish more RDMs
+4. revamp RIOT website (see [Web Revamp Task Force](https://github.com/RIOT-OS/RIOT/wiki/Website-Revamp-Task-Force))
+
+
+
+# Low-level Hardware Support
+(contact/steering: [Alex](https://github.com/aabadie))
+
+1. Improved MIPS support
+2. radio support for TI SensorTag
+3. radio support for Silab Thunderboard
+4. ESP32 support
+
+
+
+# Testing
+(contact/steering: [Kaspar](https://github.com/kaspar030))
+
+1. ~~automated unit tests with hardware in the loop (SAMR21 plugged on CI server?)~~ (done, Murdock and Philipp)
+2. automated network functionality tests (e.g. RPL + UDP/PING tests through border router, multi-hop) in IoTLAB dev sites?
+3. ~~leverage PiFleet more?~~ done, 1. uses PiFleet
+4. On-board CI testing in IoT-LAB (as it will provide soon the possibility to add custom nodes)
+
+
+
+# Security
+(contact/steering: [Kaspar](https://github.com/kaspar030))
+
+1. RNG unified (secure, or basic), seeding
+2. easy TinyDTLS integration in sock, with CoAP etc.
+4. RIOT default configuration = secure configuration (that's our goal/motto)
+5. 802.15.4 link layer security (gaps in RFCs? How to update keys?)
