Introduction to Paper Presentation on Mobile Computing:

Mobile computing is fast growing technology ,paper presentation on Mobile Computing explains in detail about this topic.Now a day’s cellular technology is the most widely used technology. It works on the frequencies that connect to millions of the users. Earlier analog technology was used that was based on the wires to connect but they are limited to the home. Then in 1990s GSM technology came that introduced the mobiles, and it becomes the mode of communication from anywhere and at any time. They use the frequency between the 890-915 MHz and 935-690 MHz for the receptions. Every cell consists of number of channels and they are needs to register to the nearest base stations.

Mobile Communications Overview Block Diagram:

Users can do data communication, it means that they can share information, or they can share file, send Mail, connect to the internet and WWW. They provides variety of networks to access data communication like PSTN, ISDN, or ATM. They all are partly analog and digital. They either do packet switching or circuit switching. In circuit switching data are sending from one user to other user and they have to follow the specific path. If in case the link that you are busy then your message cannot be redirected and that might create delay. While in case packet switching they utilize the network efficiently, they break the message in to small parts and they are sending in to packets. In mobile phones user can move from one place to other place and they can talk while walking also.

Circuit Switched CDPD Diagram:

Mobile computing-CDPD technology:

Today mobile communication is dominated by the CDPD technology. In this system if your communication idle then you are not charged for that. This reduces the cost of the communication and slow transmission.

While CDPD networks allow it users to connect the users to connect with fixed link. They always connect to the existing network and transmit the data with the help of circuit switch.

Mesh Networking Seminar Report covers in depth information on this topic here we explain about basic out line of the topic.This topic explains about concept of networking in which each node needs to capture its data but also they disseminate their own data. They are depended on the other nodes and then they send the data in to the network. They are designed with the help of routing or flooding. When we send message on the network then message travel on the path by jumping from one node to others nodes and in this way they reach the destination.

The connection we create must be continuous and they must be connected to each other. Mesh Network is something like MANET, or ad hoc networks. To resolve the problem of continuous network we have to use self-healing based algorithms. It does not allow to break even single node and it make the connection reliable. These types of networks are used in the wireless networks.

A mesh Networking Example:

Different Types of Network in Wireless Mesh Network:

Zigbee: it is the high level communication that uses very low power.  They are based on the IEEE standard that used radio signals for communication. They are used in different applications. They are developed for personal networks. They can be used in the light switches, meters, or home appliances that will operate on your message send by from cell phone. They are not expensive like other WPANs such as Bluetooth. They are developed for short range communication. They can send data at the speed of 250 kbps.

Wi-Max: they are also the wireless networks. They are wireless broadband networks that work like telecom operators. They send signals using high towers. It is also called 4G. They send the data at the speed of 75Mbits per sec.  

Wi-Fi: they are wireless network that are limited to the building or college campus. They can be used in the mobile and the Laptops for internet connection. they can also be used in the other device that have Wi-Fi feature.
