“…With the availability of multiple radio bands like 2.4/5 GHz, 60 GHz, and VHF/UHF band for license-exempt Wi-Fi operation, it is expected the near future Wi-Fi-enabled devices to support multiple radio bands [24]. Depending upon the design of such multi-band Wi-Fi devices the various radio bands can be opportunistically utilized as mentioned in some use cases below.…”

With the rapid proliferation of bandwidth intensive content, a newer technology is essential as 802.11 a/b/g cannot satisfy the requirements, like higher bandwidth. The latest generation, 802.11n, is the answer and helps accelerate the uptake of Wi-Fi integration in CE (Consumer Electronic) devices. Nowadays, most of CE devices are Wi-Fi-enabled and the unprecedented growth causes a dearth of bandwidth for WiFi operation. We present the various standardization activities in progress by industry alliances and international standard organizations to assuage the bandwidth paucity problem by defining protocols for Wi-Fi operation in the available licenseexempt spectrum in VHF/UHF (Very High Frequency/Ultra High Frequency) and 60 GHz band. The expansion of Wi-Fi to CE coupled with the new standardization initiatives creates new usage models like P2P (Peer-to-Peer) communication, WirelessDisplay, Smart Grid applications, etc., that are also articulated in this work.

“…However, multi type traffic and utilization are not taken into account. Infact, none of these works [1,3,4,10,13,15] propose any scheduling algorithm for multi-band MRs considering multi-class traffic or perform any queuing analysis to measure difference performance metrics.…”

“…In cell networks, services are provided for wide range area for many users and bandwidth is shared by multiple users while Wi-Fi only provide services for short range area for several users. Authors [13,15] explain possible Wi-Fi architecture with multiple physical and link layers to support multiple frequency bands simultaneously. In [3,4,10], authors proposed the usage of 60 GHz frequency band to attain faster data H. S. Narman et al transfer rate in wireless networks.…”

“…There have been several research works [1,3,4,[10][11][12][13][14][15] reported in the literature that attempt to extend single band technology through the use of multiple frequency bands, leading to increased bandwidth while reducing interference. Even though multi-band usage has been widely investigated in cell networks [11,12,14], it is a relatively new concept in wireless networks.…”

A recent trend in Internet usage has seen large amounts of multimedia data due to increasingly large numbers of mobile users. To facilitate higher bandwidth, modern mobile routers are capable of supporting simultaneous multi-band, leading to less interference, higher capacity and better reliability. However, there exists neither previous work that attempts to maximize utilization of available bandwidth in order to increase performance of multi-band mobile routers through the sharing of traffic classes among different frequency bands of the multi-band mobile router by scheduling, nor that shows multi-band routers are better than single band routers in realistic scenarios. In this paper, we have proposed a novel scheduling algorithm for multi-band mobile routers which transmits different classes of traffic through different frequency bands to achieve improved performance. We have developed an analytical model to perform queuing analysis of the proposed scheduling algorithm for multi-band mobile routers and derived various performance metrics, validated by extensive simulations. Our results show that the proposed scheduling model can improve performance by ensuring maximum possible utilization through sharing of capacities among the bands in multi-band systems. We show our results by comparing proposed multi-band scheduling model with single and current multi-band scheduling models. In addition, we compare single and multi-band mobile routers. It is evident from our results that multi-band systems are not always better than single band systems although multi-band systems are expected to have better performance. Based on the results, we have listed recommendations for selecting single or multi-band systems and allocation policies according to traffic conditions, and their priorities. Our proposed scheduling algorithms and related analysis will help network engineers build next generation mobile routers with higher throughput and utilization, ensuring less packet loss of different classes of traffic.

An increasing number of internet connected devices access large multimedia files over the Internet. Therefore, the bandwidth demand is exponentially increasing. To satisfy users' demands, multi-band wireless routers, which simultaneously support several bands, are developed. However, current multiband routers do not attempt to maximize the utilization of frequency bands nor consider the energy consumption. There are a limited number of previous works on multi-band wireless routers and those works do not address the energy efficiency and utilization problems of multi-band routers. Therefore, we have proposed an energy aware scheduling algorithm to ensure maximize utilization of multi-band routers while decreasing energy consumption through band sharing. Results show that the proposed method uses system resources efficiently and decreases energy consumption of the multi-band systems up to 60%. Our proposed scheduling algorithm and related analysis will help network engineers build next generation wireless routers by considering performance metrics such as throughput and energy usage of multi-band Wi-Fi routers.
