This paper investigates a method to distributively solve a Network Utility Maximization
(NUM) problem with coupled variables and applies it to study power control in wireless …

With the rapid development of wireless sensor networks, reducing energy consumption is
becoming one of the important factors to extend node lifetime, and it is necessary to adjust …

We extend the existing network utility maximization (NUM) framework for wired networks to
wireless sensor networks by formulating it in order to take into account interference among …

Wireless sensor networks (WSNs) are energy-constrained in nature, in this paper, we
formulate the problem of data transport in sensor networks as a network utility maximization …

Utility-based power control in wireless networks has been widely recognized as an effective
mechanism to managing co-channel interferences. It is based on the maximization of system …

In Network Utility Maximization (NUM) problems, it is generally assumed that user utilities
are uncoupled, ie, each utility depends only on local variables. Then the coupling in …

In this paper, we study the utility-lifetime tradeoff in wireless sensor networks (WSNs) by
optimal flow control. We consider the flow control in a more practical way by taking into …

The possibility of using network utility maximization as a distributed optimization technique
for enforcing resource sharing has not been investigated for wireless sensor network (WSN) …

Wireless sensor networks (WSNs) are energy-constrained, as a result, energy allocation and
data transmission on sensor nodes are always considered together. However, current …

In wireless sensor networks, many sensors face energy constraints and can switch among
different work modes to save energy. How to properly schedule work modes is important for …
