Abstract:
Future cellular networks are expected to consist of macro-cell
overlaid with small-cells; these multi-tire deployments pose challenges
to mobility management procedures like Handover. It's important to
achieve a successful Handover procedure to reduce the probabilities of
Handover Failure and Radio Link Failure which are the Handover
performance metrics, by selecting appropriate Time-To-Trigger (TTT)
according to inter-site distance and user's velocity; this was proposed as
technique to improve the Handover performance. In this research using
MATLAB to view the appropriate Time-To-Trigger value for the user
for each Handover performance metrics according to the inter-site
distance and user's velocity. The results indicated that the proposed
technique achieved an improvement in the Handover performance by
selecting appropriate Time-To-Trigger value for the user in each intersite
distance for specific velocity (60Km/h).
