Integration of vehicular ad-hoc network (VANET) and cellular network is a promising architecture for future machine-to-machine applications. This integration helps the vehicles have steady internet connection through cellular network (i.e., LTE), and at same time communicate with other vehicles. However, dead spot areas and unsuccessful handoff processes due to the high speed of vehicles that can disrupt the implementation of this kind of architecture. In this chapter, simplified cluster-based gateway selection (SCGS) scheme for multi-hop relay in VANET network is proposed. The scheme is achieved by utilizing a new routing protocol called an enhanced hybrid wireless mesh protocol (E-HWMP). The simulations results show that SCGS scheme through E-HWMP protocol performed better than ad-hoc on demand distance vector (AODV) routing protocol. Furthermore, SCGS scheme through E-HWMP is compared with other cluster-based gateway selections used in the previous works; the result shows that SCGS scheme through E-HWMP protocol outperforms the other cluster-based gateway selections schemes.

Aodv Routing Protocol

Workers or labors who are working in construction sites are prone to severe risks such as death, injuries happened due to accidents, falls and stuck in between objects. Internet of things (IoT) based sensors can be utilized to monitor the behavior of workers when they are in danger zones/areas. To safeguard site workers, supervisors or site managers should monitor and alert them when they are in danger. Data will be routed from site worker to supervisor, during this routing process data is subjected to routing attacks such as black hole attack and so on, due to wireless transmission. This article addresses the problem of black hole attack that happens during the wireless transmission between nodes and the base station (BS) of IoT-based civil construction. The proposed solution Collaborative Black Hole Attack – Ad Hoc On-Demand Distance Vector routing protocol (CBHA-AODV) prevents the collaborative black hole attack by 87.72%.

A Vehicular Ad-hoc Network (VANET) is a subclass of wireless ad-hoc networks, widely used in on-road vehicles and roadside equipment, having applications in various areas including passenger safety, smart traffic solutions, and connectivity on vehicles The VANET is the backbone of the Intelligent Transport System (ITS) that establishes connectivity between vehicles through a wireless medium. When it comes to the communication between high-speed vehicles there is the challenge of dynamic mobility. In order to provide a higher Packet Delivery Ratio (PDR) and increase the throughput, a new routing protocol called Dynamic Trilateral Enrolment (DyTE) is introduced which chooses a dynamic trilateral zone to find the destination vehicle by allowing only relevant nodes to participate in the communication process using the location coordinates of source and destination nodes. The proposed routing protocol is compared with Ad-hoc On-demand Distance Vector (AODV), Ad-hoc On-demand Multipath Distance Vector (AOMDV), and Dynamic Source Routing (DSR), and the results show remarkable improvement in reducing the Network Routing Load (NRL) and increasing the PDR and throughput of the network. DyTE has performed more efficiently in terms of PDR (23% approximately), throughput (26% approximately) and drastically minimized the NRL by a factor of almost 3.

Wireless mesh network (WMN) operates both in infrastructure and ad-hoc mode. It provides extended network coverage based on heterogeneous wireless technologies through multi-hop communications. In WMNs, the routing mechanisms and network organization need to be improved so that optimal path discovery or different protocols adaptability can be achieved. Hybrid routing is a demanding issue to be discussed these days as need of higher mobility management in the diverse situations and environments. It's required to improve the older schemes for higher data rate and minimum energy consumptions. The proposed work presents a design of a novel routing algorithm for optimal route discovery, congestion reduction, dynamic route selection and scalability in hybrid mesh networks. The authors have focused on Hybrid Routing Protocols to originate a novel routing scheme based on AODV (Ad hoc On-Demand Distance Vector routing protocol) in Ad-Hoc level with clustering scheme and DSDV (Destination Sequence Distance Vector) as proactive routing protocol in Backbone Mesh Router Level to form a new hybrid routing protocol. In this work a Novel Hybrid Distance Vector (NHDV) routing protocol algorithm has been introduced, which is the combination of DSDV (Destination Sequence Distance Vector) and AODV routing protocols. A clustering scheme with the combination of two efficient clustering schemes for Ad-hoc mesh client levels is discussed in detail and a performance metric for DSDV is also discussed which ETX (Expected Transmission Count) is for measuring packet loss ratio at each link for higher throughput. A new performance metric introduced in AODV as Mesh Router Count is used to improve the performance of communication to the Mesh Routers. The proposed work is the design of new algorithm that presents an optimal solution in bringing out a revolutionary change to Hybrid Routing.

Aodv Routing Protocol

Wireless Sensor Networks (WSN’s) have gained a considerable importance and are used for a variety of applications. In WSN, an arrangement of sensor nodes is done to sense and collect information from its nearby environment and to send it back to the base station using routing protocol. The biggest challenges are how to handle the routing problems and to optimize the energy consumption in WSN. In this paper, performance evaluation of three energy models, Generic, Micaz and Micamotes, is presented using Ad-Hoc On demand Distance Vector (AODV) routing protocol. The performance evaluation is done using several parameters: Throughput, Jitter, Average End-to-End Delay (AEED), Total Packets Received (TPR) and Energy consumption inthree modes (transmit, receive and idle). Based on the evaluation, it has been found that Micamotes energy model using AODV routing protocol consumes less energy by 80.46% and 428.57% in transmit mode , 102.94% and 335.6% in receive mode from Micaz and Generic energy models, respectively.
