Từ những hạn chế kể trên thì hƣớng phát triển của đề tài nhƣ sau:
- Tiếp tục nghiên cứu chi tiết về các phƣơng pháp làm giảm độ trễ chuyển giao ở lớp 2 (Layer 2).
- Phân tích, tổng hơp các phƣơng pháp đã nghiên cứu để đề xuất phƣơng án tối ƣu hơn cho quá trình chuyển giao với độ trễ nhỏ nhất.
- Hoàn thiện hơn quá trình mô phỏng quá trình chuyển giao trên Omnet++ sử dụng Inet framework.
- Tiến hành thí nghiệm chuyển giao trên thiết bị thật nếu có điều kiện. - Từ những kết quả đã nghiên cứu cho chuyển giao lớp 2 sẽ là tiền đề để
