Topology control is fundamental to solving scalability
and capacity problems in large-scale wireless ad hoc and sensor
networks.
Forthcoming wireless multi-hop networks such as ad hoc and
sensor networks will allow network nodes to control the
communication topology by choosing their transmitting ranges.
Briefly, topology control (TC) is the art of co-ordinating
nodes’ decisions regarding their transmitting ranges, to
generate a network with the desired features. Building an
optimized network topology helps surpass the prevalent scalability
and capacity problems.
Topology Control in Wireless Ad Hoc and Sensor Networks
makes the case for topology control and provides an exhaustive
coverage of TC techniques in wireless ad hoc and sensor networks,
considering both stationary networks, to which most of the existing
solutions are tailored, and mobile networks. The author introduces
a new taxonomy of topology control and gives a full explication of
the applications and challenges of this important topic.
Topology Control in Wireless Ad Hoc and Sensor
Networks:
* Defines topology control and explains its necessity,
considering both stationary and mobile networks.
* Describes the most representative TC protocols and their
performance.
* Covers the critical transmitting range for stationary and
mobile networks, topology optimization problems such as energy
efficiency, and distributed topology control.
* Discusses implementation and ‘open issues’,
including realistic models and the effect of multi-hop data
traffic.
* Presents a case study on routing protocol design, to
demonstrate how TC can ease the design of cooperative routing
protocols.
This invaluable text will provide graduate students in Computer
Science, Electrical and Computer Engineering, Applied Mathematics
and Physics, researchers in the field of ad hoc networking, and
professionals in wireless telecoms as well as networking system
developers with a single reference resource on topology
control.

Tentang Penulis
Paolo Santi is Researcher at the Instituto di Informatica e
Telematica del CNR in Pisa, Italy, a position he has held since
2001. He received the ‘Laurea’ Degree and the Ph D in Computer
Science from the University of Pisa in 1994 and 2000. respectively.
During his career, he visited the School of Electrical and Computer
Engineering, Georgia Institute of Technology, in 2001, and the
Department of Computer Science, Carnegie Mellon University, in
2003.
During his Ph D Studies, Dr. Santi’s research activity focused on
fault-tolerant computing in multiprocessor systems. Starting from
2001, his research interests shifted to wireless ad hoc networking,
with particular focus on the investigation of fundamental network
properties such as connectivity, network lifetime, and mobility
modeling, and on the design of energy-efficient protocols.
Dr. Santi has contributed more than twenty papers in the field
of wireless ad hoc and sensor networking, and has been involved in
the organizational and technical committee of several conferences
in the field. Dr. Santi is a member of ACM and SIGMOBILE.
