The container as a service is a new trend in the world of technology before the virtual machines were used but now, the CaaS has replaced all these and now it is gaining immense popularity. The researchers conducted before concentrated on virtual machines placed over physical machines or containers. But now this practice leads to the underutilized or over-utilized physical machines and virtual machines too. The main objective of this examination is to the usage of the assets as far as CPU's and memory size of the Virtual machine and Physical machines and instantly minimizes the number of used physical machines and virtual machines in the cloud environment. This proposed architecture will analyze the good fit (GF) and large fit (LF) based on a good fit with a given fitness function. And as a resultant the proposed Ant colony optimization (ACO) -GF placement algorithm performs when compared to GF and LF and maintains significant improvements and positive results.

In cloud computing, the cloud provider agent offers the quality of service (QoS) for different categories of cloud consumer agents. In general, the inter-cloud environment provides resources as a virtual machine (VM) instance representing processing power, Memory allocated in RAM, and secondary storage for consumer agents with QoS guarantees. A service level agreement framework with a reinforcement learning mechanism is considered for provisioning VM’s for all categories of client classes. The parameters like cost of service, availability, and service demand are considered while provisioning VM’s in the inter-cloud environment. QoS violation happens because another set of cloud consumer agents receives the less no of VMs. In our approach, the adaptive resource provisioning is integrated with reinforcement learning mechanism during the service admission process and ensures the collaborated cloud providers will gain more profits without violation of SLA.

Cloud Computing works as the best solution for providing many of its services for cloud consumer agents with different requests for huge computational VM's with large storage capacity. The instance requests of cloud consumers will dynamically change as per their usage of application requirements with the demand for business growth, and singlevendor cloud becomes a constraint to satisfy these needs of the cloud consumers. Federated Cloud can contribute its solution approaches to meet these dynamic needs of cloud consumer requests of resource instances. The interoperability of clouds was made realistic with cloud federation. This paper provides an optimized solution approach where a set of collaborated cloud providers will provide services to satisfy consumer agents' multiple requests. It presents the two-phase collaborated resource provisioning (CCRP) approach and Most Cost-Effective Collated Providers Resources First (MCECPRF) algorithm. The algorithm's efficiency has been tested with specific data set for optimizing the cost for cloud consumer agents and analyzes the cancellation of requests, decision time for provisioning for different VM configurations within specific time slots.

Mobile ad hoc networks (MANETs) are subjected to attack detection for transmitting and creating new messages or existing message modifications. The attacker on another node evaluates the forging activity in the message directly or indirectly. Every node sends short packets in a MANET environment with its identifier, location on the map, and time through beacons. The attackers on the network broadcast the warning message using faked coordinates, providing the appearance of a network collision. Similarly, MANET degrades the channel utilization performance. Performance highly affects network performance through security algorithms. This paper developed a trust management technique called Enhanced Beacon Trust Management with Hybrid Optimization (EBTM-Hyopt) for efficient cluster head selection and malicious node detection. It tries to build trust among connected nodes and may improve security by requiring every participating node to develop and distribute genuine, accurate, and trustworthy material across the network. Specifically, optimized cluster head election is done periodically to reduce and balance the energy consumption to improve the lifetime network. The cluster head election optimization is based on hybridizing Particle Swarm Optimization (PSO) and Gravitational Search Optimization Algorithm (GSOA) concepts to enable and ensure reliable routing. Simulation results show that the proposed EBTM-HYOPT outperforms the state-of-theart trust model in terms of 297.99 kbps of throughput, 46.34% of PDR, 13% of energy consumption, 165.6 kbps of packet loss, 67.49% of end-to-end delay, and 16.34% of packet length.
