This paper studies the techno-economic design of a green cellular base station, with an emphasis on the effect of changing cellular traffic design patterns on the design and the maintenance costs. The projected changes in traffic due to changes in internet usage patterns will be mapped to changes in electric load for the cellular base station. The effect of such changes on the optimum design and on...
We present a distributed joint power control and transmit beamforming selection scheme for multiple antenna wireless ad hoc networks. Under the total network power minimization criterion, a joint iterative beamforming and power control algorithm is proposed to reduce mutual interference at each node. Total network transmit power is minimized while ensuring a constant received signal-to-interference...
In this paper, we propose an efficient bottleneck throughput maximizing routing framework for correlated data gathering in wireless sensor networks. Our proposed routing metric exploits the the data correlation present in sensor networks. For throughput-maximizing correlation aware routing, a game theoretic framework is developed for a local solution of the NP-complete optimization problem. The proposed...
This paper examines the use of the Receiver Initiated Busy Tone Medium Access (RI-BTMA) protocol in a dense ad hoc network. The RI-BTMA protocol is known to eliminate the hidden and exposed node problems in sparse networks where a transceiver will see one active link or none at all. When multiple links are active, their busy tone signals will interfere. This paper addresses the phase synchronization...
In this paper, we consider the problem of interference suppression by performing a joint iterative beamforming [1] and channel allocation (JIBCA) strategy for wireless nodes under contracted quality-of-service (QoS) constraints in an ad hoc network. The objective is to maximize the signal to interference plus noise ratios (SINRs) between two communicating nodes under constant transmit power considering...
