A Location Management Strategy Based on Dual Location Areas in LEO Satellite Network

Efficient Location Management Based on Moving Location Areas

Personal Communication Systems (PCS) maintain a Location Management mechanism for tracking the location of their mobile users. The increasing population of mobile users leads to congestion problems in these systems, and motivates the development of more efficient management schemes. This work presents a new mobility management scheme that integrates the location area approach with the location ...

Strategy-proof Location on a Network

We consider rules that choose a location on a graph (e.g. a road network) based on agents’ single-peaked preferences. First, we characterize the class of strategy-proof, onto rules when the graph is a tree. Such a rule is based on a collection of generalized median voter rules (Moulin, 1980) satisfying a consistency condition. Second, we characterize such rules for graphs containing cycles. We ...

Network Management in ATM LEO Satellite Networks

Development of the past decade have confirmed that ATM technology has the potential of becoming the transport mechanism in many multimedia networks where high-speed traffic and Quality of Service guarantees must be provided. More recently, we have witnessed a surge of interest in Low Earth Orbiting (LEO) satellite networks with on-board ATM switches, which hold the promise of offering an econom...

Coordinated Multibeam Satellite Co-location: The Dual Satellite Paradigm

In the present article, a new system architecture for the next generation of satellite communication (SatComs) is presented. The key concept lies in the collaboration between multibeam satellites that share one orbital position. Multi-satellite constellations in unique orbital slots offer gradual deployment to cover unpredictable traffic patterns and redundancy to hardware failure advantages. T...
