说明：  粒子群算法，也称粒子群优化算法（Particle Swarm Optimization），缩写为 PSO， 是近年来发展起来的一种新的进化算法(Evolutionary Algorithm - EA)。PSO 算法属于进化算法的一种，和模拟退火算法相似，它也是从随机解出发，通过迭代寻找最优解，它也是通过适应度来评价解的品质，但它比遗传算法规则更为简单，它没有遗传算法的“交叉”(Crossover) 和“变异”(Mutation) 操作，它通过追随当前搜索到的最优值来寻找全局最优。这种算法以其实现容易、精度高、收敛快等优点引起了学术界的重视，并且在解决实际问题中展示了其优越性。粒子群算法是一种并行算法。(Particle swarm optimization (PSO), also called particle swarm optimization (Particle Swarm Optimization), is abbreviated as PSO, which is a new evolutionary algorithm (Evolutionary Algorithm EA) developed in recent years. PSO algorithm is a kind of evolutionary algorithm. It is similar to simulated annealing algorithm. It also starts from the random solution and finds the optimal solution by iteration. It also evaluates the quality of the solution through fitness, but it is simpler than the genetic algorithm rule. It does not have the crossover (Crossover) and the Mutation operation of genetic algorithm. Search for global optimum. This algorithm has attracted the attention of the academic community for its advantages of easy realization, high accuracy and fast convergence, and has shown its superiority in solving practical problems. Particle swarm optimization (PSO) is a parallel algorithm.)

说明：  在车载网络中，尤其是在城市环境下，车辆高速移动导致网络拓扑结构频繁变化，车辆密度分布不均，导致稀疏连通和局部最优情况频繁出现，所以必须专门为车载自组网设计具备鲁棒性、可靠性、实时性的路由协议。本章针对现有城市环境下存在的车辆碰撞问题，利用车辆的地理位置和电子导航地图提供的道路车流信息进行路由决策，根据设定的城市交通网络模拟图，随机的分布车辆节点，通过十字交叉路口的防碰撞研究以及路边节点之间的相对位置预警仿真，得到不同仿真下的城市交通信息网络结果图，对于该区域交通通信设计以及路况信息改善有一定的指导意义(In the vehicular network, especially in the urban environment, the high-speed movement of vehicles leads to frequent changes in network topology and uneven distribution of vehicle density, which leads to the frequent occurrence of sparse connectivity and local optimization. Therefore, it is necessary to design a routing protocol with robustness, reliability and real-time for vehicular ad hoc networks. Aiming at the problem of vehicle collision in the existing urban environment, this chapter uses the geographic location of the vehicle and the road traffic flow information provided by the electronic navigation map to make routing decisions. According to the set urban traffic network simulation diagram, the vehicle nodes are randomly distributed.)
