Extensive empirical studies presented in this article confirm that the quality of radio
communication between low-power sensor devices varies significantly with time and …

Topology control plays an important role in the design of wireless ad hoc and sensor
networks; it is capable of constructing networks that have desirable characteristics such as …

Ultra-wideband (UWB) is an emerging wireless physical layer technology that uses a very
large bandwidth. We are interested in finding the design objectives of the medium access …

Wireless Heterogeneous Sensor Network (WHSN) facilitates ubiquitous information
acquisition for Ambient Intelligence (AmI) systems. It is of great importance of power …

Power scheduling and localization play important roles in network topology management.
Distributed power scheduling is an efficient way to construct a reliable and energy-efficient …

We propose a new power control algorithm capable of managing the topology of a vehicular
ad hoc network by adjusting transmission power dynamically. Our algorithm is simple to …

The use of effective clustering algorithms can extend the life of wireless sensor networks. In
general, the clustering algorithm should have the ability to reduce the energy requirement …

Transmission power control in ad-hoc networks has hitherto been used only for achieving
connectivity of networks. It has been implicitly assumed that the optimal throughput …

In this paper, we address the issue of transmission power control in wireless ad-hoc
networks. In general, it is assumed that the minimum transmission power required to keep …

In mobile ad hoc networks, it is often more important to optimize for energy efficiency than
throughput. In this paper we investigate the effect of transmit range on energy efficiency of …
