Optimized simplified routingalgorithm for handovermanagement in vanets acrossheterogeneous networks

Abstract

newline The next generation of mobile systems emphasizes the smooth integration of the wireless technologies that are now in use, such as UMTS, WLAN, and Bluetooth. In the near time, it is anticipated that users will be able to communicate whenever and wherever they want over heterogeneous networks, thanks to the impending cellular networks, which will have heterogeneity and ubiquity. A mobility service mustprovide one of the fundamental needs for connectivity: a widespread network. Mobile IP was developed to provide network layer support for various access technologies (such as WiMAX, WiFi, and Cellular). However, it can only offer mobility services to a single device simultaneously. There may be situations in which the joint mobility of a set of nodes is relevant in context, such as when individuals are using the Internet while riding in a vehicle, bus, plane, or train. Meaning a simultaneity in networks. newlineAnother example may be a Personal Area Network, also known as PAN, which allows a person to handle several mobile devices simultaneously, including a phone, a PDA, a laptop, and a variety of other devices capable of networking. PAN s can be created by interconnecting various devices. In these circumstances, there is a fair possibility to deliver mobility services to each indices traveling together. Hence, it is necessary to support the collective capability of a group of nodes that can preserve the connection of every node in the group, even if the point of attachment to the internet that the group uses changes within the connected network. This concept is referred NEMO (Network Mobility) in IP networks. Alternately, network mobility occurs when a whole network of IPv6 nodes travels as an entity and changes its point of attachment to the internet architecture. For example, individuals traveling in a vehicle, who access the Internet simultaneously, exemplify network mobility. The Internet Engineering Task Force (IETF) has established a working group known as NEMO (Network Mobility) to develop solutions
