Deployment of a global all IP wireless/mobile network is not a straightforward decision. Heterogeneous mobile networks combined with wireless “hot-spot” locations seams to be one of the most realistic early deployments. Commercial public wireless LAN solutions however offer proprietary location management capabilities compared to the traditional cellular networks. The increasing demands for het...

Location management is a fundamental problem in mobile computing systems. Existing industry standards employ centralized location management schemes. Centralized schemes are not highly scalable. This paper presents a new, distributed location management strategy for mobile systems. Its salient features are fast location update and query, load balancing among location servers, and scalability. T...

With the fast development of high-speed railway (HSR), the demand for mobile communication on high-speed trains is increasingly growing. This leads to significant attention on the study of resource management in HSR wireless communications with limited bandwidth. Resource management is a challenging problem due to heterogenous quality of service (QoS) requirements and dynamic characteristics of...

E ective management of battle eld networks requires a hierarchical network management architecture wherein managers can dynamically delegate management tasks to intermediate managers. In this paper we describe a novel framework called SHAMAN Spreadsheet-based Hierarchical Architecture for MANagement which extends the traditional at SNMP management model to a hierarchical architecture. We descri...
