This paper provides an in-depth look at existing topology management control algorithms in Multi-state structure. We suggest a new algorithm based on Geographical Adaptive Fidelity (GAF) and Adaptive Self-Configuring Sensor Networks Topology (ASCENT). The new proposed algorithm outperforms both GAF and ASCENT algorithms. %K Wireless Sensor Networks (WSN) %K Topology Management %K GAF %K ASCENT %K Geographical Adaptive Fidelity %K Adaptive Self-Configuring Sensor Networks Topologies %K Topology control algorithm %K Design Issues. %U http://airccse.org/journal/jwmn/1212wmn02.pdf
