Fault tolerant topology control for all to one communication holds significance in dynamic wireless networks with asymmetric wireless links. In this paper the author Investigates the various aspects of the problem mentioned above using the cone based distributed topology control algorithm. The topology of a wireless multi-hop network can be controlled by varying the transmission power at each node. If there is a path between receiver base station and the node then it will communicate with the maximum power. The author proposes a set of optimizations. It reduces power consumption and that they retain network connectivity. Dynamic configuration in the presence of failures and mobility of nodes are analyzed.
