提出的搜索协议通过两点实现洪泛协议的改进:a)以搜索预算取代TTL机制,使协议具有较好的搜索粒度;b)通过动态估计搜索副本的密度和接力搜索方式两种机制降低协议开销。仿真结果显示协议在网络开销、查询速度等方面具有较好的性能。
This paper proposed an improving flooding protocol. The main two improvements: a) to make protocol had good granularity, used search budget in the protocol instead of TTL; b) to reduce overhead, conducted on-the-fly estimation of the popularity of the searched item and relayed the search message into the network. The experimental evaluations show that the new protocol has lower message overhead and response time.
