INTRODUCTION:
Transport connections set up over wireless links are frequently plagued by problems such as high bit error rate (BER), frequent disconnections of the mobile user, and low wireless bandwidth that may change dynamically.
TCP is a reliable ordered delivery where reliability is achieved by means of retransmissions if necessary.
TCP implements congestion avoidance and control.
TCP maintains end-to-end semantics.
We discuss the implementation of our protocol called M-TCP and compare its performance against other mobile TCP implementations
Wireless Network:
It is a technology by which homes, telecommunications networks and enterprise (business) installations avoid the costly process of introducing cables into a building, or as a connection between various equipment locations.
Wireless telecommunications networks are generally implemented and administered using radio communication.
This implementation takes place at the physical level (layer) of the OSI model network structure.
Advantages of Wireless Networks:
Flexible if there is ad-hoc situation when additional workstation was required.
Implementation cost is cheaper than wired network.
Ideal for the non-reachable places such as across river or mountain or rural area.
Ideal for temporary network setups.
Applications Of Wireless Network:
Cellular phones allow easy personal communications.
Inter-continental network systems, use radio satellites to communicate across the world.
Emergency services such as the police utilize wireless networks to communicate effectively as well.
TCP (Transmission Control Protocol):
-TCP is a set of rules (protocol) used along with the Internet Protocol (IP) to send data in the form of message units between computers over the Internet.
-While IP takes care of handling the actual delivery of the data, TCP takes care of keeping track of the individual units of data that a message is divided into for efficient routing through the Internet.
- TCP is known as a connection-oriented protocol.
Conclusion:
M-TCP is good if mobile hosts suffer frequent disconnection and lengthy disconnection from the network.
Handoff is efficient by using M-TCP.
