— We consider a wireless sensor network scenario where closely packed nodes can be grouped into clusters. Although each node might have only a single antenna, nodes within a cluster can cooperate during transmission or reception, thereby forming a cooperative Multiple Input Multiple Output (MIMO) system. Much of the work in the area of cooperative MIMO has(More)
This paper presents a new distributed power control algorithm for ad-hoc wireless networks in random channel environments. Previous work in this area has focused on distributed power control for ad-hoc networks with fixed channels. We show that the algorithms resulting from such formulations do not accurately capture the dynamics of a time-varying channel.(More)
We investigate the optimal placement of transmit antennas in distributed antenna systems. Our optimization framework imposes no constraints on the location of the antennas. Based on stochastic approximation theory, we adopt a formulation that is suitable for node placement optimization in various wireless network scenarios. We show that optimal placement of(More)
System design aspects must be considered to effectively map an application onto the constraints of a smart camera network. Therefore, we propose an application-driven design methodology that enables the determination of an output set of operation parameters given an input set of application requirements. We illustrate this approach utilizing distributed,(More)
The throughput of vehicles on highways can be greatly increased by forming vehicle platoons with small inter-vehicle spacings. The control law that maintains stable operation of a platoon is dependent on the lead and preceding vehicle's position, velocity and acceleration profiles. These profiles guarantee string stability of a platoon and are transmitted(More)
