Choice Procedure

Vertical handoff takes place when a mobile incurable button from one network to one more (e.g., from WLAN to CDMA 1xRTT). The purpose of this paper is to establish the problems under which vertical handoff need to be done. The trouble is developed as a Markov choice procedure. A web link benefit feature and also a signaling price feature are presented to record the tradeoff in between the network sources made use of by the link and also the signaling as well as handling tons sustained on the network. Commonly, a mobile phone might be transferred to attain the procedures of vertical handover, thinking about just one standard, that is, the received signal strength (RSS). Making use of a solitary requirement might trigger solution disruption, an out of balance network lots, and also an ineffective vertical handover. In this paper, we recommend boosted vertical handover decision algorithm based upon several standards in the heterogeneous wireless network. As well as additionally In this paper, we research regarding 5th generation system.

Simulation Results

Transferring a huge amount of data between different network locations over the network links depends on the heterogeneous wireless network. Such a network consists of several networks with different access technologies. Traditionally, a mobile device may be moved to achieve the operations of vertical handover, considering only one criterion, that is, the received signal strength (RSS). The use of a single criterion may cause service interruption, an unbalanced network load, and an inefficient vertical handover. In this paper, we propose enhanced vertical handover decision algorithm based on multiple criteria in the heterogeneous wireless network. The algorithm consists of three technology interfaces: Long-Term Evolution (LTE), Worldwide interoperability for Microwave Access (WiMAX), and Wireless Local Area Network (WLAN). It also employs three types of the vertical handover decision algorithms: equal priority, mobile priority, and network priority. The simulation results illustrate that the proposed handover decision algorithm outperforms the traditional network decision algorithm in terms of handover number probability and the handover failure probability. In addition, it is noticed that the network priority handover decision algorithm produces better results compared to equal priority and mobile priority handover decision algorithm. Finally, the simulation results are validated by the analytical model.
