Synchronization Algorithms for SMS Based Wireless Distributed System for Electric Grid Monitor

Wireless distributed network is a distributed system based on wireless communication technology to achieve resource share and cooperation. With the gradual consummation of wireless communication network, wireless distributed network has played a more and more important role in distributed testing and controlling field. SMS is a simple text transfer protocol on GSM network. It has been widely used in distributed testing and controlling field due to its wide coverage, cheap price, convenience to use. In these systems, synchronization has become an important issue for the whole system. In this paper, we have come up with some algorithms that are easy to fulfill without sacrificing much to the systempsilas performance. These algorithms also have such advantages as low cost in practice. Our algorithms have a positive meaning to researchers in this field.
