Abstract: Mobile Computing is becoming increasingly important due to the rise in the number of portable computers and the desire to have continuous network connectivity to the Internet irrespective of the physical location of the node. Mobile Computing offers significant Benefits for organizations that choose to integrate the technology into their fixed organizational information system.

2 Ranging from wireless laptops to cellular phones and Wi-Fi/Bluetooth enabled PDA's to wireless sensor networks, Mobile Computing has become ubiquitous in its impact on our daily lives. Mobile Computing is a versatile and potentially strategic technology that improves information quality and accessibility, increases operational efficiency, and enhances management effectiveness. The goal of this paper is to point out some of the limitations, characteristics, Applications and issues of Mobile Computing . Keywords: Mobile Computing , Wireless Technology, Application , Issues, Limitation The state of the user, static or Mobile , does not What is Mobile Computing ?

Mobile Computing involves 2 .Different types of Mobile systems Mobile communication, Mobile hardware, and The following section is an explanation of the Mobile software . Mobile Computing is the ability to different types of distributed systems ranging from use Computing capability without a pre-defined the traditional type to nomadic, ad-hoc and finally location and connection to a network to publish ubiquitous ones.

4 And subscribe to information . Mobile Computing as Distributed Systems a generic term describing ability to use the Traditional distributed systems consist of a technology to wirelessly connect to and use collection of fixed hosts that are themselves centrally located information and application attached to a network if hosts are disconnected software through the application of small, from the network this is considered to be abnormal portable, and wireless Computing and whereas in a Mobile system this is quite the norm. communication devices.

5 These hosts are fixed and are usually very The term " Mobile Computing " is used powerful machines with fast processors and large to describe the use of Computing devices, which amount of distributed systems usually interact in some fashion with a central also need to guarantee non-functional information system--while away from the normal, requirements such as scalability, openness, fixed workplace. Mobile Computing technology heterogeneity, fault- and finally resource-sharing. enables the Mobile worker to create, access, Nomadic Distributed System process, store communicate information without This kind of system is composed of a set of Mobile being constrained to a single location.

6 By devices and a core infrastructure with fixed and extending the reach of an organization's fixed wired nodes. Mobile devices move from location to information system, Mobile Computing enables location, while maintaining a connection to the interaction with organizational personnel that fixed network The Mobile host has a home IP. were previously disconnected. Mobile Computing address and thus any packets sent to the Mobile is the discipline for creating an information host will be delivered to the home network and not management platform, which is free from spatial the foreign network where the Mobile host is and temporal constraints.

7 The freedom from these currently These systems are susceptible to constraints allows its users to access and process the uncertainty of location, a repeated lack of desired information from anywhere in the space. connections and the migration into different IJSER 2017.

8 The processing units (client in communications medium. Powerful Mobile client/server paradigm) are free from temporal and solutions have recently become possible because of spatial constraints. That is, a processing unit the availability of an extremely powerful and small (client) is free to move about in the space while Computing devices, specialized software and being connected to the server. This temporal and improved telecommunication. Some of the spatial freedom provides a powerful facility characteristics of Mobile Computing are based on allowing users to reach the data site (site where the following: desired data is stored) and the processing site (the Hardware: geographical location where a processing must be The characteristics of Mobile Computing hardware performed) from anywhere.
