The Vehicular Ad Hoc Network (VANET) technology is similar to the Mobile Ad Hoc Network (MANET) in operations. But due to high dynamics of vehicles as compare to mobile nodes in MANET, the routing protocols of MANET cannot be applicable for the VANET communications. The high mobility leads the challenges of frequent link breaks and hence poor Quality of Service (QOS) performance. The clustering based routing protocols solves this problems to some extent, however performing the efficient and lightweight clustering and cluster head (CH) selections is still the complex problem for VANETs. The main causes of such problems are related to key parameters such as mobility and geographical distances of vehicles while performing the clustering tasks. In given paper we present a lightweight CH selection and cluster formation by considering mobility and number of neighbors based on geographical distances of the vehicle key parameter at every clustering interval to achieve the stability in network. The superiority of this method is that it is simple and inclusively the part of regular routing operations. For each vehicle the weight is computed to become the CH using mobility and neighbors parameter, hence this method is called as Weight based Clustering for VANET (WCV) routing protocol. The simulation result proves the QOS efficient performance compared to the state-of-art protocols. The WCV protocols improved the overall throughput by 10% as compared to the recent clustering protocol and reduced the delay 7% approximately.

车载自组织网络（VANET）技术在操作上类似于移动自组织网络（MANET）。但是由于与MANET中的移动节点相比，车辆具有较高的动态性，因此MANET的路由协议无法应用于VANET通信。高移动性带来了频繁的链路中断以及服务质量（QOS）性能不佳的挑战。基于群集的路由协议在某种程度上解决了此问题，但是对于VANET而言，执行高效轻便的群集和群集头（CH）选择仍然是复杂的问题。这些问题的主要原因与执行聚类任务时的关键参数（例如车辆的机动性和地理距离）有关。在给定的论文中，我们通过在每个聚类间隔基于车辆关键参数的地理距离来考虑移动性和邻居数，从而提出了一种轻量级的CH选择和聚类形成，以实现网络的稳定性。这种方法的优势在于它很简单，并且包括常规路由操作在内。对于每辆车，都使用移动性和邻居参数计算权重，使其成为CH，因此，该方法称为基于权重的VANET簇（WCV）路由协议。与最新协议相比，仿真结果证明了QOS的高效性能。与最近的群集协议相比，WCV协议将总体吞吐量提高了10％，并将延迟降低了约7％。
