这里提供一个基于MATLAB实现的D2D节点自组织网络的路由选择算法：

function [route, distance] = d2d_routing(src, dest, nodes)
% D2D Routing Algorithm
% Inputs:
%   src: source node
%   dest: destination node
%   nodes: all nodes in the network
% Outputs:
%   route: the selected route
%   distance: the distance of the selected route

% Calculate the distance between all nodes
N = length(nodes);
distance_matrix = zeros(N, N);
for i = 1:N
    for j = 1:N
        if i == j
            distance_matrix(i, j) = Inf;
        else
            distance_matrix(i, j) = norm(nodes(i).position - nodes(j).position);
        end
    end
end

% Find the neighbors of the source node
neighbors = find(distance_matrix(src, :) <= nodes(src).communication_range);

% Find the shortest path using Dijkstra's algorithm
unvisited = 1:N;
unvisited(src) = 0;
distance = Inf(1, N);
distance(src) = 0;
previous = zeros(1, N);
while sum(unvisited) > 0
    [~, current] = min(distance .* unvisited);
    unvisited(current) = 0;
    if current == dest
        break
    end
    for i = 1:length(neighbors)
        neighbor = neighbors(i);
        if unvisited(neighbor) == 1 && distance(current) + distance_matrix(current, neighbor) < distance(neighbor)
            distance(neighbor) = distance(current) + distance_matrix(current, neighbor);
            previous(neighbor) = current;
        end
    end
end

% Construct the route
route = [];
current = dest;
while current ~= src
    route = [current route];
    current = previous(current);
end
route = [src route];
distance = distance(dest);

该算法使用Dijkstra算法找到源节点到目的节点的最短路径，并考虑了节点之间的距离、通信范围等因素。使用该算法可以实现基于D2D的移动节点自组织网络中的路由选择。
