“…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.…”

“…Usage of high frequency band (e.g., 60 GHz) provides more bandwidth though coverage area is quite small. Singh et al [1] proposed a method to assign different frequency bands to end-devices based on their distances from the access router by considering energy efficiency. However, multi type traffic and utilization are not taken into account.…”

“…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.

“…Multiband WLAN using both 2.4/5 GHz and 60 GHz or other higher frequency band has been proposed to achieve both high transmission speed and sufficient reliability [1,2,3]. In the multiband WLAN, 60 GHz is used to achieve high transmission speed and 2.4/5 GHz is used if 60 GHz is unavailable due to human body shadowing for example.…”

This letter proposes RSSI (Received Signal Strength Indicator) based 60 GHz WLAN discovery for multiband WLAN (Wireless LAN), which uses both 2.4/5 GHz band and 60 GHz band to achieve high transmission speed, sufficient reliability and power-saving of a multiband WLAN device. The proposed 60 GHz WLAN discovery detects 60 GHz WLAN coverage by using RSSI of 2.4/5 GHz WLAN signals. Space/time diversity is employed to improve the false detection probability of 60 GHz WLAN discovery. Ray-tracing simulation results confirm that 60 GHz WLAN discovery is feasible and space/time diversity is effective to improve the reliability of 60 GHz WLAN discovery.
