Location management strategies for wireless networks. A comparison study on system utilization

This paper aims to compare different location management techniques and their suitability for adaptation in the next generation wireless IP networks. It is found that in a macro-mobility environment, the pointer forwarding scheme would be the best alternative for managing mobility. Its performance is particularly promising in a scenario where a more frequent mobility pattern is to be expected. By contrast, for micro-mobility scenarios, the local anchoring scheme seems to give the most satisfactory overall performances. Although it does attract more database accessing loads, the extra signaling can be easily justified by the significant reductions achieved in the updating load
