Energy Efficiency in Wireless Sensor and Actor Networks by Distributed Time Sychnronization Algorithm

In this paper, for decrease transmissions delay in wireless sensor and actor network is suggested a distributed algorithm. Energy consumption is very important issue because they have limited energy. Current protocols due to have transmission delay in sending data among nodes cause increase consuming energy in network. Proposed algorithm is based on distributed algorithm and can solve this problem somewhat. In this algorithm, a distinguished node sends time values along a spanning tree structure periodically. One of the most important advantages of the algorithm is purely distributed and local. It does not depend on a fixed structure for disseminating time values. In conclusion, results gained shows that suggested protocol decrease transmissions delay of wireless network above 30 percent compared to the existing approaches.
