基于博弈论的无线传感器网络保密容量优化研究
ON OPTIMISING SECRECY CAPACITY IN WIRELESS SENSOR NETWORKS BASED ON GAME THEORY
摘要
Abstract
Wireless sensor network is vulnerable to being eavesdropped during data transmission because of its broadcasting nature.From the perspective of information theory,it is easy to achieve safe data transmission by ensuring the secrecy capacity between nodes’channels. However,there are interferences between nodes in wireless sensor networks,therefore the secrecy capacities of the channels their own are impacted.In this paper,we use non-cooperative game to study the way of choosing the power of the node its own to reach Nash equilibrium for acquiring best gains under the conditions that the transmission power of WSN is limited on nodes and that the nodes interfere each other. Simulation results show that while the nodes select the power in Nash equilibrium,they can obtain better secrecy capacity while improving their sustainability as well.关键词
