Thuật toán định vị lồi dựa trên sự khác biệt thời gian đến cho mạng cảm biến không dây trong ô nhiễm phóng xạ bãi thải uranium
Tóm tắt
Để giải quyết vấn đề ô nhiễm hạt nhân trong bể chứa bãi thải uranium, một công nghệ mạng cảm biến không dây mới được sử dụng để theo dõi bể chứa bãi thải uranium trực tuyến theo thời gian thực. Do đó, một thuật toán định vị lồi dựa trên sự khác biệt thời gian đến (TDOA) được đề xuất để đáp ứng yêu cầu theo dõi bể chứa bãi thải uranium. Trước tiên, khoảng cách giữa nút chưa xác định và mỗi nút neo trong phạm vi giao tiếp được thu thập bằng phương pháp định vị TDOA. Thông qua nhiều lần so sánh và sàng lọc, ba nút neo tương đối xa với nút chưa xác định được chọn. Sau đó, thuật toán định vị lồi được sử dụng để giảm vùng của các nút chưa xác định. Cuối cùng, tọa độ ước lượng của các nút chưa xác định được thu được. So với thuật toán lồi ban đầu, các kết quả cho thấy độ chính xác định vị của thuật toán đề xuất cao hơn 27% so với thuật toán lồi. Phạm vi dao động của lỗi định vị giảm 26% , đáp ứng hiệu quả nhu cầu theo dõi bể chứa bãi thải uranium.
