【摘要】 SAODV协议通过应用数字签名和哈希链,能够对抗多种网络攻击,加强了AODV协议的安全性。但SAODV协议需要大量公钥计算,对网络性能的影响非常大。本文提出一种改进的安全路由协议ISAODV,该协议采用延迟验证的思想,减少公钥计算量,有效降低了SAODV协议的能量消耗。最后通过NS2模拟验证改进协议的性能。更多还原

【Abstract】 SAODV protocol uses digital signature and hash link to enhance the security of AODV protocol.It can confront many kinds of network attacks.However,this protocol needs public key calculation,which is deeply impacts the performance of the protocol.A new protocol called ISAODV is proposed.This protocol use the thinking of delay authentication,reduce the energy consumption in SAODV protocol.The improvement is proved through Network Simulation2 at last.更多还原
