With the great success of LTE(-A) outdoor, LTE-based small cell technology has become popular and is penetrating indoor enterprise environment, co-existing with WiFi networks, to provide better user experience or Quality-of-Experience (QoE). However, accurate estimation of LTE links is challenging and critical to continue providing QoE for many enterprise(More)
LTE in Unlicensed band (LTE-U) has gained intensive attention recently due to its capability to offload mobile data to unlicensed bands. In order to use unlicensed band, LTE-U has to coexist with WiFi - another wireless technology that operates in unlicensed bands. This coexistence is riddled with several challenges as these technologies use different core(More)
A mobile-to-mobile remote computing protocol for smartphones presents a user with the ability to run an application remotely and to interact with it in a responsive way, where I/O updates can be performed midstream and the results can be viewed in real time. Even though several protocols exist for desktop remote computing, we argue that these cannot be(More)
Wireless providers today are highly motivated to improve efficiencies of spectrum usage. One approach to achieve this is to shift the load from expensive cellular networks to cheaper WiFi networks. In this context, we propose Precog, an <i>action-based prefetching</i> solution for time-shifted WiFi offloading. We argue that traditional prefetching(More)
Application Mobilization, or the ability of an enterprise employee to rely on mobile devices such as smartphones and tablets, to continue to perform business workflows even when mobile, is seen as a game changer to improve productivity. However, the practical adoption of enterprise mobility is very much in its in fancy, and seemingly has barriers. We posit(More)
Low-cost lenses with magnifications of 150-200x are being sold in the market today as accessories for mobile smartphones. Attaching these lenses to a smartphone camera creates low-cost, ultra-portable digital microscopes, with a potential for significant impact on applications in a variety of fields such as healthcare, agriculture, education etc. In this(More)
Multiple Description (MD) source coding is a technique that breaks a media stream into equally important sub-streams which can be sent over different paths for protection against channel errors in wireless networks. In this paper, we explore the possibility of sending the descriptions through different paths and intermediately merging them to exploit(More)
