Abstract: Through introducing an appropriate redundancy in directed diffusion, this paper proposes a new extended routing protocol. The basic principles of the protocol are introduced. The performance of the scheme and the detection of some flavours of attacks are given. Simulation results show that the redundancy can get a high arrival rate and the detection can be carried out smoothly. The new protocol reduces the number of data packet transmission.

摘要： 通过在定向扩散中引入适当的冗余，提出一种新的扩展路由协议。介绍新协议的基本原理和实现方法，分析协议的性能及对数据篡改、选择性转发和Wormhole攻击的检测。仿真结果表明，协议中引入的冗余数据具有很高的到达率，使依赖于冗余的检测能顺利进行，通过增加Sink节点，协议减少了数据包的传输个数。
