无线自组织网络中
移动台能量有限
为了延长生存期
需要减少中间节点之间的数据包交换次数
本文提出一种基于网络编码的数据分发机制CRNC
同基于泛洪的传统数据分发机制相比
CRNC在大幅度减少传输次数的同时
只增加了少量时延.理论分析及仿真试验
证明了采用网络编码的CRNC可以在传输时延和能量消耗上取得更好的均衡.
Mobile stations in wireless Ad hoc network usually have limited energy and may prefer fewer transmissions for longer lifetime.We propose CRNC
an efficient data distribution mechanism based on network coding
that reduces data transmissions significantly
while increasing data transmission delay only slightly as compared to the protocol based on flooding.With extensive theoretical analysis and simulations
we show that CRNC based on network coding achieves a better tradeoff between resource usage and protocol performance.
