摘要
为了优化位置服务,提出一种强弱状态信息结合的位置服务协议,该协议能动态调整位置服务策略,以适应通信需求的变化。通过实验分析了该协议的存储和通信开销,以及对上层路由协议的报文延迟和送达率的影响。实验结果表明,该协议在保持较高性能的基础上减小了开销。
To optimize location service,this paper proposed a hybrid location service protocol which combined strong state and week state in maintaining location information.This protocol could adjust location service strategy to adapt the change of communication.Analyzed storage and communication cost of the protocol and the impact to packet delay and packet delivery success rate of upper routing protocol by experiment.The experiment result shows this protocol can decrease cost on the basis of maintaining high performance.
