The Research on Various QoS Restrains Routing Protocol Base on Game Theory of WMSN

This paper put forward an improved MMSPEED routing algorithm basing on Game Theory through detail researches and analysis of existing routing protocol and combining the specialties of Wireless Multimedia Sensor Network (WMSN). This algorithm takes advantage of Nash Equilibrium to pick out the optimal path of revenue from source node to sink node; and elect paths which are suitable to different information to process information transmission by adjusting revenue function, considering there are various information types in WMSN and different information has different demands to QoS. Simulation tests indicate the improved protocol is better-adapted toWMSN where multi types of information coexist, and balance the energy consumption under the circumstance of less rising of frame loss rate,to prolong the working time, and also improve the instantaneity and reliability.
