“…This control channel is used for channel assignment and superframe scheduling with channel diversity. Romaniello et al designed a Multi-Channel Beacon Train (MCBT) protocol [22] that accelerates the process of joining the network, which is critical for energy harvesting nodes. They can indeed scan the channel continuously for much shorter periods than non-rechargeable battery operated nodes.…”

Reliable wireless communication even in adverse conditions is the key for building the energy efficient and dependable Internet of Things. In this paper, we explore the benefits of channel diversity for enabling efficient wireless communication: we propose MRR (Multi-channel Round-Robin), a backwardcompatible evolution of beacon-enabled IEEE 802.15.4 in which energy constrained nodes take advantage of additional active periods operating on different channels in a round-robin way. Each active period starts with a beacon sent on a cyclically changing channel, which then allows an associated device to transmit data on the channel used for the beacon. MRR schedules the additional active periods at carefully selected instants to avoid direct beacon collisions. To motivate our work, we first experimentally corroborate previous findings that channel diversity is an effective way of mitigating variable or poor transmission conditions. Then, we observe that channel diversity improves the quality of transmission even better than expected-it appears that wireless sensor nodes have a radiation pattern that changes significantly from one frequency channel to another, which often results in a considerably improved gain when using the right communication channel. The evaluation of the MRR scheme through measurements on a real indoor multihop testbed shows that the proposed scheme results in significantly improved Packet Reception Ratio even without resorting to e.g. channel blacklisting. These results confirm the benefits of multichannel operation and exhibit a fully functional solution that does not add a large overhead compared to using a single channel.

“…The recent work of Karowski et al [9] lowered this cost by optimizing the number of slots to listen over different channels. Romaniello et al [16] proposed the Multichannel Beacon Train Protocol for faster discovery over multiple channels in the presence of varying beacon intervals. Kohvakka et al discussed a protocol that carries the time offset and the frequency channel in beacons to ease the scanning process for the joining node [11].…”

Abstract-In this paper, we propose a new scheme that allows coupling beacon-enabled IEEE 802.15.4 with the RPL routing protocol while keeping full compliance with both standards. We provide a means for RPL to pass the routing information to Layer 2 before the 802.15.4 topology is created by encapsulating RPL DIO messages in beacon frames. The scheme takes advantage of 802.15.4 command frames to solicit RPL DIO messages. The effect of the command frames is to reset the Trickle timer that governs sending DIO messages. We provide a detailed analysis of the overhead incurred by the proposed scheme to understand topology construction costs. We have evaluated the scheme using Contiki and the instruction-level Cooja simulator and compared our results against the most common scheme used for dissemination of the upper-layer information in beaconenabled PANs. The results show energy savings during the topology construction phase and in the steady state.

“…Due to the relevance of this access mode in IEEE 802.15.4, the Internet Engineering Task Force (IETF) "IPv6 over the TSCH mode of IEEE 802. 15.4e" (6tisch) working group has been formed with the aim of defining new standards for enabling the usage of IEEE 802. 15.4e TSCH also in IPv6 networks [8].…”

“…15.4e network, it is possible to establish a multi-hop mesh composed by a set of synchronized nodes. In this way, all nodes share a common time slotted baseline, organized as a periodic sequence of slotframes, and they can wake up only in those timeslots according to the needs of higher layer protocols.…”

The Time Slotted Channel Hopping (TSCH) Medium Access Control (MAC) has been introduced in the recent IEEE 802.15.4e amendment to improve energy efficiency and reliability of short range wireless communications in industrial applications. However the joining phase can take very long time due to the operation of TSCH and beside being a problem in the deployment phase it may become a relevant source of energy consumption. To overcome this issue the present contribution investigates the problem of acquiring the first synchronization in a TSCH network from several points of view: (i) two novel mechanisms are proposed and implemented in real motes to speed up joining operations; (ii) for each of them, the average joining time is analytically modeled with closed form expressions as a function of node density, communication reliability, and beacon transmission frequency; (iii) the effectiveness of these novel algorithms and the accuracy of their models are experimentally validated in different scenarios.
