Description Synchronization is a critical enabler for several communication techniques. In most cases it is achieved by means of an external common source (such as GPS) or by distribution techniques (clock trees). Unfortunately they do not apply to wireless indoor nodes. Leaderless synchronization are meant to cope with this problem and proposes to achieve synchronization in a distributed way, by consensus techniques. Literature on leaderless synchronization has not explored yet solutions where the nodes can be assigned different weights for the consensus algorithms: this corresponds to the situation where different nodes can provide distinct clock stability and, consequently, are expected to be preferable to drive consensus.

The thesis will study this problem through Matlab and NS-2.
