A New Multiple Service Key Management Scheme for Secure Wireless Mobile Multicast
Addressing key management in mobile multicast communication is currently a booming topic due to the convergence of wireless and mobile technologies. With the proliferation of multiple group based services that are possible to co-exist within a single ...
A Privacy-Preserving Framework for Managing Mobile Ad Requests and Billing Information
Organizations are starting to realize the significant value of advertising on mobile devices, and a number of systems have been developed to exploit this opportunity. From a privacy perspective, practically all systems developed so far are based either on ...
An Efficient Auction-based Mechanism for Mobile Data Offloading
The opportunistic utilization of third party WiFi access devices to offload customer traffic from the mobile network has recently gained momentum as a promising approach to increase the network capacity and simultaneously reduce the energy consumption of ...

Every night, many smartphones are plugged into a power source for recharging the battery. Given the increasing computing capabilities of smartphones, these idle phones constitute a sizeable computing infrastructure. Therefore, for an enterprise which ...
Exploiting Error Estimating Codes for Packet Length Adaptation in Low-Power Wireless Networks
We propose Plena, a packet length adaptation scheme exploiting recently proposed error estimating codes (EEC) for low-power wireless networks. We carefully consider two low-power MAC protocols in modeling the energy consumption of different packet ...
Link Capacity-Energy Aware WDC for Network Lifetime Maximization
With the increase in flexibility and capabilities of wireless networks, the use of distributed computing over wireless network environments is being researched in order to maximize network sustainability and interoperability among distributed nodes. To ...
Performance Analysis of TCP NewReno over a Cellular Last-Mile: Buffer and Channel Losses
TCP NewReno is one of the most widely deployed TCP versions in today's Internet. However, a full understanding of the complex inter-dependencies between the losses due to wireless channel errors and those due to buffer overflows, and their (joint) impact ...
Performance Modeling and Analysis of IEEE 802.11 IBSS PSM in Different Traffic Conditions
The IEEE 802.11 standard for wireless local area networks defines a power management algorithm for Independent Basic Service Set (IBSS) allowing it to save critical battery energy in low powered wireless devices. The power management algorithm for IBSS ...
Profit Improvement in Wireless Video Broadcasting System: A Marginal Principle Approach
In this paper, we address the problem of how to make the wireless service provider have better profits with consideration of user experience provision in wireless video broadcasting systems. We propose a marginal-based pricing and a resource-allocation ...
QoS-Aware Power-Efficient Scheduler for LTE Uplink
The continuous increase of mobile data traffic has created a substantial demand for high data rate transmission over mobile networks. However, mobile devices are provided with small batteries that can be drained quickly by high data rate transmission. ...
Restricted Epidemic Routing in Multi-Community Delay Tolerant Networks
In some specific applicable scenarios, nodes are placed in some geographical areas and limited to move in their own community. We investigate the tradeoff between the delivery delay and the number of transmissions in the above multi-community delay ...
Sensing Human-Screen Interaction for Energy-Efficient Frame Rate Adaptation on Smartphones
Touch-screen technique has gained the large popularity in human-screen interaction with modern smartphones. Due to the limited size of equipped screens, scrolling operations are indispensable in order to display the content of interest on screen. While ...
Simplicial Homology for Future Cellular Networks
Simplicial homology is a tool that provides a mathematical way to compute the connectivity and the coverage of a cellular network without any node location information. In this paper, we use simplicial homology in order to not only compute the topology of ...
Single-Hop Transport Throughput of Secondary Networks in Spectrum Sharing Systems
In order to improve the spectrum efficiency, spectrum sharing systems allow multiple systems to utilize the same spectrum with different priorities. Typically, the primary network performs as a stand-alone network while the secondary one accesses the ...
Tracking Message Spread in Mobile Delay Tolerant Networks
We consider a delay tolerant network under two message forwarding schemes-a non-replicative direct delivery scheme and a replicative epidemic routing scheme. Our objective is to track the degree of spread of a message in the network. Such estimation can ...
WiScape: A Framework for Measuring the Performance of Wide-Area Wireless Networks
We present WiScape, a framework for benchmarking and understanding the behavior of wide-area wireless networks, e.g., city-wide or nation-wide cellular data networks using active participation from clients. The goal of WiScape is to provide a coarse-...
