“…In addition, in order to avoid potential problems related to the coverage of IEEE 802.11, sub-GHz Wi-Fi (IEEE 802.11AH) [48] may be also considered in the future for the NAN in rural scenarios, where distances are higher, but data rates are lower. In such rural scenarios, it is also worth considering White Spaces [49].…”

Abstract:Reducing electricity consumption and integrating renewable power generation sources represent two of the main drivers of the so-called Smart Grid. Machine-to-Machine (M2M) communications will play a key role on making such a Smart Grid a reality, since they will enable the required bidirectional real-time bulk information exchange. However, communications for the Smart Grid present specific requirements from both technical and economic perspectives, so it is crucial to evaluate how existing communication architectures and technologies meet them before undertaking the important investments needed to deploy this kind of infrastructure on a large scale. The main goal of this paper is to evaluate, from different perspectives, the core M2M communications infrastructure of a platform designed to reduce electricity consumption and integrate renewable generation at residential level. Such a communications infrastructure is fully based on widely deployed wireless communications technologies such as IEEE 802.11 and General Packet Radio Service (GPRS). Notably, the paper assesses the operational costs of using different security solutions in the GPRS segment and the performance of the selected communications technologies based on different metrics (goodput, in the case of IEEE 802.11, and transmission time, in the case of GPRS).

“…IEEE 802.11ah adalah protokol jaringan nirkabel yang beroperasi pada bands sub 1 GHz untuk dapat menyediakan tambahan jangkauan jaringan Wi-Fi yang lebih luas, jika dibandingkan dengan jaringan Wi-Fi konvensional yang bekerja di atas bands 2,4 GHz dan 5 GHz [12]. Hal tersebut juga memengaruhi penggunaan energi yang rendah dengan membuat beberapa station atau sensor memungkinkan saling berbagi sinyal.…”

Abstract. In order to cope with the rapid development of the Internet of things, IEEE working group has proposed a new wireless network technology, 802.11ah. IEEE 802.11ah operates at sub 1GHz band, and can provide long transmission range, wide coverage, while supporting more than 6,000 of station to be connected. In order to alleviate the high collision probability, 802.11ah MAC protocol involves in the RAW (restricted access window) mechanism combined with grouping mechanism. However, in 802.11ah WLAN (wireless local area network), most of the stations operate at sleep mode, and it is expected that at the start of a BI, the network suffers much higher collision probability than at the latter period of the BI. In order to improve these drawbacks, we propose an adaptive contention window scheme based on which an optimum contention window size is adapted at the start of the BI, and then gradually halved when the transmission completes successfully. Through conducting simulations, we prove that our proposed protocol can enhance the performance of 802.11ah WLAN.
