A Selfish Node Preventive Real Time Fault Tolerant Routing Protocol for WSNs

摘要

Selfish behaviors of nodes in real-time wireless sensor networks can cause massive packet loss or even VOID regions, a game theory based real time fault tolerant routing protocol, namely GTRF, is proposed in this paper. In GTRF, a game theoretical VA model is developed to tolerate faulty nodes, balance energy cost and regulate the nodes' behaviors. To guarantee real-time transmission, a skipping transmission manner is adopted. Simulation results show that GTRF can not only efficiently balance the energy cost but also can prolong the life time of the network.
