As the cloud computing is a new style of computing over internet. It has many advantages along with some crucial issues to be resolved in order to improve reliability of cloud environment. These issues are related with the load management, fault tolerance and different security issues in cloud environment. The load can be CPU load, memory capacity, delay or network load. Load balancing is the process of distributing the load among various nodes of a distributed system to improve both resource utilization and job response time while also avoiding a situation where some of the nodes are heavily loaded while other nodes are idle or doing very little work. Load balancing ensures that all the processor in the system or every node in the network does approximately the equal amount of work at any instant of time. In existing system, several works exist on load sharing and load balancing in other networks such as mobile computer network, homogeneous and heterogeneous system, and cognitive radio network. The existing system had some drawback such as, low connectivity, presence of misbehaving users, and inefficient protocol design with respect to energy consumption, QoS provisioning, and resource allocation. In this project the system propose a truthful auction-based QoS guaranteed load sharing scheme in MCN. And the proposed system design a utility maximization problem for quality-assured secured load sharing (QuaLShare) in MCN. And also the proposed system address the problem of QoS-guaranteed secured service provisioning in MCNs. The proposed truthful load sharing scheme is required for avoiding such inefficiency of CSP. This system establish the existence of Nash Equilibrium (NE) in the proposed scheme.
