Message delay analysis of serial processing system with vacation in WSN

Many wireless sensor networks (WSN) application systems are composed of multiple sensor nodes serial processing system. This paper sets up the model for the serial processing system using gated service in wireless sensor networks, and studies it by the Markov chain theory and the probability generating function method, the calculating equation of the mean waiting time of message packet is obtained by every sensor node in the serial processing system. We obtain corresponding results under some especial cases. Finally, the simulation results are given.
