Location Management in Wireless Cellular Networks
Travis Keshav -- traviskeshav@hotmail.com
Abstract
Cellular networks are spreading rapidly, leading to overloaded systems, unacceptable delays, and increasing computational costs due to inefficient Location Management [LM]. This paper evaluates both past/present cellular practices and shortcomings in LM, presents recent theoretical proposals to overcome current flaws, indicates probable trends towards future cellular LM, and covers the E911 service and its use of LM.
