Our objective is to use information on the vehicles approaching an intersection to control the traffic signal. Recent work in this area has used this information to minimize the average delay of vehicles controlled by the signal. We demonstrate that, when there are significant differences in the volume of traffic approaching from different directions, the average delay of the vehicles in the lo...

In this paper, we study rate allocation for a set of end-to-end communication sessions in multi-radio wireless mesh networks. We propose cross-layer schemes to solve the joint rate allocation, routing, scheduling, power control and channel assignment problems with the goals of maximizing network throughput and achieving certain fairness. Fairness is addressed using both a simplified max-min fai...

This paper presents virtual clusters based proportional fairness and resource allocation scheme for Localized Single Carrier Frequency Division Multiple Access (L-SC-FDMA). L-SC-FDMA has been selected as the uplink transmission scheme in 3GPP Long Term Evolution (LTE) due to its low Peak to Average Power Ratio (PAPR) over OFDMA in general and high rate-sum capacity over Interleaved SC-FDMA in p...

We consider connection-level models of resource allocation in the Internet, where files arrive into the network according to a Poisson process and the size of each file is exponentially distributed. For a simple symmetric three-link star network, we derive the optimal resource allocation policy which minimizes the expected number of files waiting in the system. The performance of the optimal po...

Multicast is an efficient means of transmitting the same content to multiple receivers while minimizing network resource usage. Applications that benefit from multicast are now being deployed over 3G wireless data networks. Existing multicast schemes transmit data at a fixed rate assuming there is always a user at the edge of the cell. In general, users belonging to the same multicast group can...

Efficient radio resource allocation algorithm is proposed in this paper. Proportional fair algorithm gives favorable performance compared to two classical algorithms max-C/I and RR. But PF algorithm does not consider QoS parameters while allocating resources to the users. Moreover with less transmission power utilization Fairness disappears in PF algorithm. A PFQoS-Centric is proposed in this p...
