Analysis of Methods for Reducing Topology in Wireless Sensor Networks

This paper describes the phases of deployment of wireless sensor networks, and more attention is given to the phase of reducing topology and to methods by which this can be achieved. A comparison of hierarchy-based topology construction algorithms is presented. Algorithms use a simple, distributed and energy efficient topology mechanism that discovers a optimal connected dominant set (CDS) to disable unnecessary nodes, providing important wireless sensor network characteristics such as full coverage and connectivity.
