Location Management in Wireless Fourth Generation Networks

Satisfying quality of service (QoS) is one of the main goals of the wireless fourth generation (4G), which will integrate tightly a multitude of different heterogeneous networks including cellular networks (second generation, third generation, wireless local area networks, bluetooth, etc). In this paper, we develop an information-theoretic framework for optimal location updating and paging for wireless 4G network, which integrate tightly many different access networks. Then, we adopt the LZW compression algorithm as the basis of our location management schemes. Simulation results demonstrate that our proposed schemes decrease the signaling cost.
