Evaluation of WiseMAC and extensions on wireless sensor nodes

Abstract

In the past five years, many energy-efficient medium access protocols for all kinds of wireless networks (WSNs) have been proposed. Some recently developed protocols focus on sensor networks with low traffic requirements are based on so-called preamble sampling or lowpower listening. The WiseMAC protocol is one of the first of this kind and still is one of the most energy-efficient MAC protocols for WSNs with low or varying traffic requirements. However, the high energy-efficiency of WiseMAC has shown to come at the cost of a very limited maximum throughput.In this paper, we evaluate the properties and characteristics of a WiseMAC implementation in simulation and on real sensor hardware. We investigate on the energyconsumption of the prototype using state-of-the-art evaluation methodologies. We further propose and examine an enhancement of the protocol designed to improve the trafficadaptivity of WiseMAC. By conducting both simulation and real-world experiments, we show that the WiseMAC extension achieves a higher maximum throughput at a slightly increased energy cost both in simulation and real-world experiments.

“…Wise MAC is also an energy efficient MAC protocol, which is defined in [12] and [13]. Wise MAC is based upon non persistent CSMA and reduces power consumption by using preamble sampling and by reducing idle listening.…”

Energy-efficient Medium Access Control for Transmit Reference Modulation

“…For example, one transmitter may use a single bit to request the receiver to keep listening to receive more packets after receiving one packet. For example, WiseMAC with more bit [40], and an extension of WiseMAC with stay awake promise [57] are such kind of protocols. BEAM [58] allows one node to double its duty cycle based on a specific request from the transmitter.…”

“…Furthermore, this approach reduces the end-to-end delay for burst traffic. The authors in WiseMAC More bit extension [57] propose an enhancement of WiseMAC with an overhearing technique and stay awake promise. Using this technique, one receiver node stays awake for a longer time after receiving a request from a sender node.…”

“…In this section, we simulate the TR-MAC protocol to analyze its performance in a multiple access scenario. For simulation, we implement the TR-MAC protocol in OMNeT++ simulator with MiXiM simulation framework [57]. OMNeT++ is a discrete event simulator to analyze a wireless protocol using events occurring at discrete time instances.…”

“…The impact of an event as the time progresses can be analyzed on the protocol level using the OMNeT++ simulator. MiXiM is a simulation framework that uses the OMNeT++ simulator for simulating wireless communication scenarios [57]. MiXiM uses protocol stacks for all the layers of OSI model.…”
