In Next Generation (NG) Wireless Networks, end-user is supported with more technologies. Each of the network system has its own characteristic. To utilize best features of each network system, a new architecture “Enhanced Architecture for ubiquitous Mobile Computing” has been introduced. Furthermore, load-balancing algorithms have been introduced in this architecture. These algorithms will run after a specified amount of time and all NIAs will broadcast load request to update the load values on each of the NIA in the database. Mathematical performance analysis has been carried out to prove the need for the new architecture and its algorithms.
