“…The practicality of these assumptions can be questioned. CMAC [59], unlike MMSN and [58] which are both synchronous protocols, does not require time synchronization. However, it needs to assign every node a channel that does not overlap with any other node in 2-hop range.…”

“…Also, when the number of channels is small, it can be seen from the paper that MMSN consumes more energy than single-channel CSMA. [58] proposes another protocol for cluster-based WSN. The protocol is shown to be more energy efficient than MMSN by assuming (i) all cluster heads can directly communicate with each other and (ii) there are many sink nodes and hence no single-sink bottleneck.…”

Abstract-Distributed Information SHaring (DISH) is a new cooperative approach to designing multi-channel MAC protocols. It aids nodes in their decision making processes by compensating for their missing information via information sharing through other neighboring nodes. This approach was recently shown to significantly boost the throughput of multi-channel MAC protocols. However, a critical issue for ad hoc communication devices, i.e., energy efficiency, has yet to be addressed. In this paper, we address this issue by developing simple solutions which (1) reduce the energy consumption (2) without compromising the throughput performance, and meanwhile (3) maximize cost efficiency. We propose two energy-efficient strategies: in-situ energy conscious DISH which uses existing nodes only, and altruistic DISH which needs additional nodes called altruists. We compare five protocols with respect to the strategies and identify altruistic DISH to be the right choice in general: it (1) conserves 40-80% of energy, (2) maintains the throughput advantage gained from the DISH approach, and (3) more than doubles the cost efficiency compared to protocols without applying the strategy. On the other hand, our study shows that in-situ energy conscious DISH is suitable only in certain limited scenarios.

Abstract-Multi-Channel Dynamic Scheduling has been centric stage of research in WSNs in recent years. In this paper, we propose a Distributed Multi-Channel Scheduling MAC communication protocol (DMS-MAC) to improve the network performance of WSNs, which selects the best channel for an individual wireless sensor node. DMS-MAC supports dynamic channel assignment mechanism where each sensor node is equipped with a directional antennas. The proposed protocol helps to decrease the probability of collision, interferences and improves the overall network performance of Wireless Sensor Networks (WSNs). The protocol is most suitable for short packet transmission under low traffic networks and has ability to utilize parallel transmission among neighboring nodes and achieves increased energy efficiency when multi-channels are available. Simulation result shows that the proposed protocol improves the performance of aggregate throughput, probability of successful transmission, packet delivery ratio, energy consumption and average end-to-end delay.

“…WirelessHART is a TDMAbased system which uses a centralized scheduling mechanism. WirelessHART and all the proposed multi-channel solutions in WSNs [13], [1], [10] require a tight time synchronization and extensive signaling overhead to communicate and to be able to keep channel switching times consistent even when there is no need for communication in the near future [14]. Moreover, because these protocols require communication schedules to be computed and distributed (using a centralized manager) in advance, it is relatively expensive (design, time, and energy) to adapt the network to new topologies or load situations.…”

“…periodically changing the communication channel. Channel hopping is known to substantially improve communication reliability in WSNs [3], and therefore it has been adopted in recent standards for industrial wireless sensor networks, for example Wireless-HART and ISA100.11a, see [17], [11], [13] [1]. Both Wireless-HART and ISA100.11a rest on a TDMA approach with slow-hopping, i.e.…”

Abstract-We propose a novel decentralized and self-learning framework to support both communication reliability and energyefficiency for periodic traffic applications in WSNs. Our autonomous framework comprises three main components: estimation and identification of multi-flow traffic, dynamic multi-flow wakeup scheduling, and asynchronous channel hopping. With asynchronous channel hopping the frequency hopping pattern is determined by each source node autonomously, and forwarders have to identify and follow the pattern. We also propose a light and efficient controller to eliminate the collision caused by multiflow overlap at forwarders. We present design and evaluation of our autonomous framework using real world measurements, and realistic trace-based simulation. The results show that our asynchronous channel hopping solution improves the packet reception rate compared to the single channel solutions without the need of an expensive signaling and time synchronization overhead. We also show that with this scheme the average energy consumption yields a ≈ 50% lower than the single channel solutions. This paper is to the best our knowledge, the first to explore channel hopping without maintaining a tight time synchronization protocol.
