Horticulture is the science of sustainable production, advertising and marketing the intensively cultivated food and decorative plants. The major intricacy in horticulture is maintaining the temperature within the controlled environment such as polyhouse or green house which leads to plant damage like root rot, leaf spots, downy mildew. This results in IoT of human intervention in checking the temperature periodically and provide remedial measures to maintain it. In order to overcome such issues this work proposes an IoT-based Automatic Temperature Controller (ATC) system using Arduino board interfaced with the environmental data by deploying Internet of Things (IoT). The proposed work incorporates two phases: (i) Collection of data for the different floral plants and uploading it to the IoT cloud (ii) Implementing the hardware part using Arduino UNO kit for ATC system. The ATC system gets the values of temperature and humidity from DHTII sensor where, the entire system is connected to the Arduino microcontroller which compares the recorded value with the threshold value set by user in cloud. The motor will be turned on by the controller being the observed temperature is found larger than the threshold value. The proposed system has been tested on different floral plants that are of high productivity in and around Hosur, Tamil Nadu circumstances namely Gerbera daisy, Button rose, Chrysanthemum and Rose. This work can be extended for other agricultural application purposes like creepers, mushroom cultivation etc.

Vehicular ad hoc networks (VANETs) require optimal routing mechanisms for routing in highly dynamic environments. The most dynamic environment is subject to dynamic changes and a lack of central coordination. The combination of bio-inspired algorithms with reactive approaches is a suitable choice to deal with the dynamic characteristics of VANETs. In this regard, hybrid bio-inspired zone routing protocol (HyBIZRP) proposes to find the optimal shortest path with a limited number of vehicles for routing messages. In HyBIZRP, phase 1 follows a modified proactive mode and phase 2 follows an enhanced reactive mode for routing. Using modified Ant Colony Optimization (ACO) in HyBIZRP provides optimal routing with low overhead and delay. The proposed HyBIZRP and existing works are simulated in Network Simulator (NS 2). Important metrics such as throughput, packet delivery ratio (PDR), overhead (OH), and end-to-end delay (EED) were used to compare the proposed HyBIZRP with proactive enhanced bio-inspired routing algorithm (EBIRA), reactive improved distance-based Ant Colony Optimization Routing (IDBACOR), and Enhanced Hybrid Ant Colony Optimization Routing Protocol (EHACORP). The simulation outputs show that the proposed HyBIZRP is superior in all aspects compared to EBIRA, IDBACOR, and EHACORP.

Vehicle ad-hoc networks (VANETs) are a subclass of mobile ad hoc networks (MANETs). The VANETs communication framework is used to provide communication between moving vehicles in highway and urban road scenarios. Dynamic properties of VANETs, such as high dynamic topology, frequent route failure, high mobility of nodes, and bandwidth constraints, reduce the efficiency of routing. The long length route between source and destination affects the efficiency of the protocol in the form of high overhead, frequent disconnections, high packet loss rate, low packet delivery rate, and low throughput. In this paper, we propose an Enhanced Hybrid Ant Colony Optimization Routing Protocol (EHACORP) to improve the efficiency of the routing process using the shortest path. The shortest path in the proposed protocol has low communication costs and the least number of hops between source and destination vehicles. The EHACORP has two phases. In phase 1, the EHACORP relies on a distance calculation method to compute the distance between vehicles. In phase 2, the source-based ant colony optimization is used to guide the ants to build a shorter path with the least number of hops to transmit data. The shortest path improves the efficiency of protocol in all aspects. The simulation results show that the EHACORP has improved packet delivery rate, throughput, end-to-end delay, routing overhead, and packet loss rate compared to Fuzzy based ant colony optimization (F-ANT), Ad hoc on-demand distance vector (AODV), ant colony optimization routing algorithm (ARA), and AntNet routing protocols.

Vehicular ad hoc networks (VANETs) demands reliable communication mechanisms for time-critical communication between vehicles. In VANETs, communication links between vehicles are prone to frequent breaks due to high mobility and topology changes. In this context, this work presents an enhanced bio-inspired routing algorithm (EBIRA) to provide reliable communication. In EBIRA, enhanced ant colony optimization (EACO) finds the optimal long-life short-distance routes with the minimum hops based on distance, received signal strength metric, hop count, and evaporation rate. In EBIRA, the selected path has a short distance and a high level of connectivity at the link level with minimum hops. Choosing the shortest path through minimum hops with high connectivity level links improves route lifetime and reduces frequent link breaks between vehicles. Simulation results show that the performance of EBIRA is better than reliable route discovery by using ant colony optimization (RDACO) and road-aware geographic routing protocol (RAGR) in terms of packet delivery ratio, throughput, and latency. Furthermore, variations of the received signal strength based on vehicle density and speed are evaluated, and the EBIRA route discovery success ratio is estimated and shown based on vehicle density at speed.

Intelligent Transportation Systems (ITS) are required for efficient vehicle communication in the smart city. The goal of ITS was to provide a broad range of services in transportation, safety, comfort, commercial, mobility, and connectivity applications. In this era, road traffic is a major annoyance. The provision of real-time traffic information to drivers, in conjunction with a navigation system, can enable vehicles to choose the best route. To support ITS, this work proposes a Hybrid Multi-hop Routing Mechanism with Intelligent Transportation System (HMRM-ITS) for efficient communication among vehicles in vehicular ad hoc networks (VANETs). The proposed HMRM-ITS employs the multi-hop routing concept to enable vehicles to improve their driving performance and road safety. Furthermore, the proposed HMRM-ITS allows the transportation organization to communicate instantly between vehicles to Road-Side Units (RSUs), as well as vehicles-traffic servers in an efficient manner. The proposed mechanism enhanced the complete spatial use of a road network by lowering average travel costs of vehicles with a 5-10% reduction in traffic overhead over existing mechanisms. Additionally, the HMRM-ITS outperforms existing mechanisms in the form of packet transmission delay and throughput.

Vehicular ad hoc networks (VANETs) provide similar services at various service points, so selecting the efficient service among the available services is a crucial task. Similarly, accessing services to exchange time-critical messages demands secure schemes. In this work, an efficient group-based dual mode key management (G-DMKM) scheme is proposed to select efficient service and the secure route to access the service. In G-DMKM for each session, the base stations are grouped according to localization in a time window manner which restricts the key and group lifetime. The time-domain randomization technique is used to generate a group key for each group and is shared between all stations and vehicles. Vehicles are authenticated for communication based on group and private keys. The private key is generated by the base station under which the vehicle is located. In G-DMKM, the multi-attribute location selection approach (MALSA) computes the multi-attribute service fitness (MASF) for each service to select the optimal service from the available services. Furthermore, Secure Transmission Support (STS) estimates the STS value for each route identified towards the service point, and the route with the highest STS support is selected for secure access to the service and data transmission. Simulation results show that the inclusion of an STS-supported route improves G-DMKM efficiency in all aspects compared to the conditional privacy-preserving authentication (CPAS), Proxy Based Authentication Scheme (PBAS), and Secure Privacy-Preserving Authentication Scheme with Cuckoo Filter (SPACF).
