【Abstract】 The recent availability of advanced location techniques and the need for the design of power-efficient and scalable networks provided justification for applying location-aided routing methods in wireless sensor networks.Concentrated on schemes that were loop-free,localized,and utilized a single-path or multi-path strategy,which were desirable characteristics for scalable routing protocols.Then we would illustrate and qualitative compare existed location-aided routing protocols and recovery strategies corresponding.更多还原
