"Topology issues in Wireless Sensor Networks"

Mr. Mo Li


Abstract:

Topology issues have received many attentions in Wireless Sensor
Networks. While many WSN applications attempt to provide optimized network
topology, the topology control itself is also under intensive study for
reliable and energy efficient network construction and maintenance.
Existing approaches employ topology directed routing and cooperating
schemes as well as sensor coverage based and network connectivity based
mechanisms in order to achieve better monitoring and communicating ability
with prolonged system lifetime. In this survey, we categorize the previous
works and make a comprehensive study on them. We discuss different
sub-problems, aiming at providing a full scale view on this area. By
summarizing existing achievements and analyzing the open issues, we point
out several possible research directions in future.
