Abstract Designing an intelligent transportation system (ITS) for vehicular ad hoc networks (VANETs) with seamless connectivity and appropriate energy conservation of roadside units (RSU) that takes part in communication between vehicular nodes is a challenging task because of the high mobility or dynamic nature of these networks. The nodes in the VANET whether stationary or moving are limited in terms of storage capacity, reliability, and energy. The main concern about these networks is whether the existing protocols meet the demands of feasibility of this high mobility VANETs and make them less dynamic or stable. In this paper, we discuss a clustering-based architecture designed with mobile agents and a combination of MH-LEACH and power-efficient gathering in sensor information systems (PEGASIS) protocols for building stability in VANET for seamless communication along with energy conservation of other RSU to improve quality of service.

networks that necessitates direct communication between nodes than relaying on a centralized architecture [3]. Vehicles in a VANET have many constraints with which they move around communicating with each other through wireless links. This network does not depend on any special hardware setup, and the entire network stability is managed by each node in the network [6]. Moreover, to build an optimized communication system within the network and to maintain the scalability and stability of this network researches show that hierarchical clustering is the best approach to offer efficient solution [4]. Clustering is necessary to achieve basic network performance. The grouping process of nodes in a dense population is known as clustering [1]. This clustering process should be dynamic and should be periodically updated to reflect changes in its environment and the time taken to form the cluster should be minimal [2]. It is a fact that in VANET reconfiguration is often required in cluster formation. Therefore, a good VANET clustering algorithm should seek to regulate rather than eliminate cluster changes. The algorithm we apply should provide an optimal and stable solution; otherwise, the overhead associated with reconfiguration and information exchange wil
