Several MAC layer power control protocols have been proposed to address the limited power supplies in ad hoc networks. Recent protocols suggest varying the transmission power such that the RTS/CTS handshake is done at the maximum, and the Data-ACK are transmitted at the minimum necessary transmission power level. It has also been suggested to periodically use maximum transmission power during D...

Today’s power consumption is the critical issue in MANET. Since, we have limited battery power to operate nodes. Due to the lack of power (Energy), the nodes “die out” from the network. Recently, power control in mobile ad hoc networks has been the focus of extensive research. Energy of nodes is consumed according to transmission power required by the radios. In this paper, we develop a mechani...

in this paper, first, a new criterion, titled “surplus percent of the customers” is defined for static transmission expansion planning in restructured power systems. then by a simple example, the new criterion is compared with some already presented market-based criteria and it is shown that the new criterion can realistically evaluate the transmission network expansion from the market view. in...

In this paper we address the issue of controlling transmission power in power-aware adhoc networks. We argue that minimum transmission power is not always optimal. Previous work that minimizes the transmission power does not consider both the energy consumed in collision resolution and the energy disbursed to overcome the interference resulting from neighboring nodes. We investigate the basic t...

Transmission power control in multihop wireless networks is a challenging problem due to the effects that different node transmission powers have across the layers of the protocol stack. In this paper, we study the problem of transmission power control in IEEE 802.16 mesh networks with distributed scheduling. We consider the effects of transmission power control on the link-scheduling performan...

Generators typically regulate terminal voltage via automatic voltage regulator and exciter equipment. The desired high side (transmission side) voltage schedule is usually maintained by the power plant operator or by slow SCADA-type process control computers. Power system dynamic performance, however, can be improved by faster regulation of the transmission voltage. Contrasted to generators, st...

Transmission power control in ad-hoc networks has hitherto been used only for achieving network connectivity. It has been implicitly assumed that the optimal throughput performance in ad-hoc networks can be achieved when using the minimum transmission power required to keep the network connected. However, in this paper we argue that such an assumption remains valid only under high node densitie...

In the IEEE 802.11p WAVE system, applications can directly control the transmission power of the messages sent in WAVE Short Message Protocol (WSMP). This feature enables the vehicles to control the transmission range based on the application requirements and/or the vehicle density. Seemingly straightforward, however, the distributed power control between vehicles can easily go awry. Unless car...
