Influences of Link Status of Wireless Sensor Networks on Key Negotiation

Because of the higher loss rate of wireless sensor networks,key negotiation can not be completed only in once.A metric with higher discrimination,namely weighting secure connectivity,is proposed to research the influences of the link status of wireless sensor networks on key negotiation.By analyzing the factors of affecting key negotiation and simulating on various network models,the law of influences of link status on key negotiation is found.The simulation results and analysis show that the secure connectivity is better if the distance between nodes accounts for about two fifths of the longest communication distance.
