Abstract:
Mobile communication technology aims to provide the seamless continuous connection to access various wireless technologies and to maintain this connection with the best quality of service (QoS).To achieve this goal a good decision making algorithm should be considered to decide the best QoS for its service. Handover decision making algorithm aims to provide best QoS and best user satisfaction by using different handover parameters. In this thesis the Receive Signal Strength and Signal to Interference and Noise Ratio together with the bandwidth management matrix were used in the decision making.
MATLAB was used for the evaluation of handover decision making algorithm. The results showed that as the distance increase for one user the RSS decrease in WLAN and CN. The simulation also showed that as the number of users increases the handover probability decrease due to limited resource of the selected network. It was also noticed that as the number of users increases the blocking probability increase due to the available limited resources. The results also showed that as the number of available bandwidth unit (bbu) increases the blocking probability decreases.
