Comparison of vertical handover decision-based techniques in heterogeneous networks
… of quality of service continuity is termed vertical handover or vertical handoff. Active calls that get dropped, or cases where there is discontinuity of service experienced by mobile users can be attributed to the phenomenon of delayed handover or an outright case of an unsuccessful …

Exploiting user contention to optimize proactive resource allocation in future networks
… including highly mobile networks. By using vertical handover techniques it is possible to provide uninterrupted communication as connections are dynamically switched between wireless networks as users move around. However, in a highly mobile environment, traditional reactive approaches to …

Security Management System for 4G Heterogeneous Networks
… issues which may compromise quality of service, vertical handover and security. Due to the convergence characteristic of Y-Comm, security is considered more significant than in the existing LTE and WiMax networks. These security concerns have motivated this research study to propose a novel …

Μοντελοποίηση και ανάπτυξη ετερογενών κινητών δικτύων οχήματος-προς-όχημα (Vehicle-to-Vehicle) και οχήματος- προς-υποδομή (Vehicle-to-Infrastructure) με έμφαση σε δύσκολα περιβάλλοντα μετάδοσης
… του WiMAX FBSS (Fast Base Station Switching) Handover και η σύγκρισή του με τον αντίστοχο Vertical Handover (VHO). O επόμενος στόχος ήταν ο σχεδιασμός ενός αλγόριθμου που στοχεύει στην βελτιστοποίηση του QoS του ασύρματου καναλιού κατά την περίπτωση ενός ασύρματου κινούμενου ετερογενούς …

Network access selection in heterogeneous wireless networks
… multiple on-going calls may need to perform a vertical handover from one RAT to another. One of the major issues in HWNs is how to select the most suitable RAT for multiple handoff calls, and the selection of a suitable RAT for multiple-calls from a single-homed multi-mode terminal in HWNs is a …

A Simulation Framework for Service Continuity over Multi Access Wireless Networks
… of the users due to mobility in the form of handover algorithm. The proposed algorithm will consider the coverage of the node, direction and speed of the user, the network load, the air interface availability and the user equipment capabilities. Another main objective of this research is to …
