INTRODUCTION

A cloud is a framework that gives computing services, executed in a dealt with, a powerfully adaptable and a versatile way. Mobile cloud computing is a combined form of cloud computing, mobile computing and wireless network. Mobile cloud computing gadgets, for example, cell phones and tablets are turning into a signicant part of our advanced and virtual way of life. It provides a wide range of computational resources to many users like mobile phone users, cloud service providers and network operators. With the help of cloud services many mobile applications can be designed quickly and delivered easily to different devices. Mobile cloud computing empowers clients or users to rapidly and safely gather and coordinate information from different sources, paying little heed to where it lives. When we are using mobile cloud computing, it is not necessary to install the client application on the phone of the recipient and can be easily accessed with the help of a web browser from a remote web server.

By using the concept of mobile cloud computing, the traditional cloud computing concept of sharing a pool of resources over the internet in a pay per use method can be done very efficiently using our mobile phones. There are so many challenges to be solved in this area. Here we are discussing some of the architectures of mobile cloud computing and its comparison. In the next section we discuss about the various challenges faced by the mobile cloud computing along with its advantages and

disadvantages. The last section deals with the various applications of the mobile cloud computing.

1. The general architecture of mobile cloud computing [1]shows that the mobile devices are connected to the mobile networks through the base stations which includes base receiver station, access points or satellite. These base stations establish and control the connections between the devices and the networks. The information and the request of the user are transmitted to the CPU connected to the server of the service provider. Based on the data of the subscriber stored in database, the services like authentication, authorization are provided to the mobile users by the service providers. The request of user is given to the cloud which is processed by the cloud controller and gives the user the requested service.

   The mobile cloud computing architecture consist of three different layers[2]

   1. This layer comprises of numerous mobile cloud service users who access the service of cloud utilizing their mobile phones. These mobile phones interface with the mobile network layer through wireless access points(WAPs), Base Tranceiver Station(BTS) or Satellite.
   2. This layer includes various mobile network operators which handle clients’ solicitations and information is conveyed through base stations.

   This layer comprises of numerous cloud computing providers which give a wide range of cloud computing services including IaaS, PaaS, and SaaS. These cloud computing providers are versatile and can be expanded or decreased dependent on what cloud computing service clients request. Cloud computing furnishes services to clients incorporating those with mobiles can get to cloud services through the Internet.

2. MAJOR MOBILE CLOUD COMPUTING ARCHITECTURES
   1. A Mobile-Cloud Collaborative Trac Light Detector for Blind Navigation.[3] propose a contextaware route framework for the visually impaired and the blind which requires computationally intense image and video handling algorithms. Basically, it is an arrangement of exceptional camera glasses associated with a mobile gadget through Bluetooth innovation. Using this the blind people can rely on WiFi based location tracking system and Text to Speech (TTS) abilities.
   2. A Virtual Cloud Computing Provider For Mobile Devices [4] propose a structure for making virtual mobile cloud computing suppliers to address the issue of availability to cloud computing resources which isn’t constantly accessible and now and again costly. Specifically, the proposed system utilizes mobile gadgets as a virtual cloud computing supplier by distinguishing close by mobile gadgets which are steady (i.e., hubs with less burden). This permits load balancing without associating with an IaaS cloud service provider.
   3. Device-to-device-based heterogeneous radio access network architecture for mobile cloud computing[5] This article proposes a hierarchical cloud computing architecture to improve performance by adding a mobile dynamic cloud which is formed by powerful mobile devices A device to device communication is used for data transmission between the devices in a heterogenous wireless architecture. The main objective of this architecture is to increase in overall capacity of a mobile network through improved channel utilization and traffic offloading from Long Term Evolution- Advanced to device-to-device communication links.
   4. Security Architecture for Mobile Cloud Computing [6] It proposes a minimalist of mobile cloud computing architecture which is designed in such a way that it ensures the organizations that make legitimate request are granded access to encrypted data.
   5. Mobile Cloud Computing Model Using the Cloudlet Scheme for Big Data Applications[7]It proposes that we use mobile cloud computing service to execute the jobs in the cloud and accessing the result using the mobile phones and thus saving memory increasing the processing power. This is an architecture based on cloudlet concept. In this model it is not necessary for the mobile device to communicate with the cloud server and it gets connected to the cloudlet directly with the help of technologies which are not expensive.
   6. Multillayer Architecture model for mobile cloud computing paradigm[8] This architecture promotes an adaptation to changing environments and enables a dynamic scaling of computational power able to assume a variable and for intensive application workload in a more effective manner than existing proposals.
3. <>CHALLENGES IN MOBILE CLOUD COMPUTING We use the concept of mobile cloud computing forthe effective use of mobile phones with an extra benefit of accessing the resources from cloud environment. But it has many challenges and it should be solved properly. Some of the main challenges are
   • Network Latency and limited bandwidth in the mobile network[10]:The main challenge of mobile cloud computing from transmission channel is because of the intrinsic behavior and constraints of wireless networks and devices. The mobile broadband networks require more execution time for an application to execute in cloud
   • Mobility Management: In case of heterogenous network it is difficult to integrate dissimilar wireless networks.
   • Context Processing: We use mobile devices to collect various information like weather condition, users voice, gestures etc. So there arises challenges like storing and managing these information.
   • Security and privacy: It is difficult to manage the threats on mobiles when compared to other devices as it is a wireless network and there are chances of getting no information.
   • Elasticity: Sometimes the cloud providers need to provide more resources than they actually have. I such cases unavailability or interruption in accessing resources occur.
4. ADVANTAGES OF MOBILE CLOUD COMPUTING The important advantages of mobile cloud computing

   are
