ABSTRACT
Most of the Telemedicine Centers maintenance cost is very high. Mostly the Telemedicine centers have hierarchical
structure of Network Model. Telemedicine Nodes are maintenance from VSAT to TM Foundation, TM division to TM
Nodes. This hierarchical structure of maintenance cost is very high. My research work is proposed Telemedicine
using computer communication Network by distribute network sharing structure, so all the TM nodes are act as a TM
Foundation and the maintenance cost is very low that can implement to rural area. We need framework design of
telemedicine network for low cost telemedicine network maintenance for Mode 1 is the communication control mode
that is applied to set the client’s communication status; Mode 2 is a point-to-point mode that makes clients able to
have point-to-point communication; Mode 3 is a group working mode that provides the multipoint-to-multipoint
communication. TM using computer communication network can be transmitted all Bio-signal of ECG, EMG, EEG,
blood pressure, temperature and all images with high quality[1][2].
INTRODUCTION
VSAT based telemedicine network is a hierarchical
structure of telemedicine network. Mostly telemedicine
used in rural area. but needs the following back ground.
• need network division.
• need License and agreements from Network
foundation.
• need of V-Satellite Communication.
• need high frequency, bandwidth allocation with
respect distance transmission.
• need high cost for maintenance for TM foundation
or division.
• need high filter section circuit for transmission
and receiving signal.
The fig 1. model is hierarchical structure of VSAT
telemedicine networks model, If the patient 1 has to
connect and discuss to Specialist Doctor 4, the following
connectivity of single root path:
Bio-Medical Service
The main Bio medical service application are Tele
surgery, Tele-dermatology, Tele-cardiology, Tele–
radiology, Tele-psychiatry, Tele-pathology, and Telehome
monitoring etc. Bio Medical service as shown in

Mobile IP
The traditional way of IP address assignment to a node
is network dependent. It brings problem in a mobile
network environment. When a mobile node moves from
one wireless network to other network, the IP address
must be changed accordingly, while ongoing connection
must be maintained and the packets belonging to the
connection must be delivered continuously.[5][6][7].
Mobile IP is the solution to this problem. Mobile IP
users keep the same long-term IP address, ie home
address, which has the same network prefix as a network
called home network. When a Mobile Node determines
that it is connected to a foreign network, it acquires a
care-of address in addition to its home address. Care-of
address is a forwarding address for a roaming mobile
node. In mobile IP, packets destined for the mobile node
are always sent to the mobile’s home network. When a
mobile node moves to a foreign network, it gets the
care-of address from a router in the foreign network
called foreign agent. The mobile node then registers the
new location to a router in its home network, called home
agent. The home agent captures packets meant for the
roaming mobile node, encapsulates and forwards it to
the foreign agent.
Telemedicine Protocol
In order to discuss about the protocol architecture, we
need to examine the following case. When MN_1 is
attached to its home network and located within
coverage area of the AP, it has one hop to HA_1. MN_1
can use MIPv6 mechanism available from HA_1 to
communicate with another node. In the mean time,
MN_1 can also communicate directly to another node in
a peer-to-peer fashion using ad hoc network based on
medium access control (MAC) WLAN ad hoc mode.
Therefore, that MN has two mechanism links over MAC
WLAN ad hoc mode, namely MIPv6 over ad hoc mode
and MIPv6 over ad hoc network The tele medicine MN
specifications are defined in a protocol architecture
describing the functionality of all layers.
Mobile Ad Hoc Network
Ad hoc literally means “formed or used for specific or
immediate problems or needs”. Thus, MANET means a
mobile network which can be formed or used for specific
or immediate problems or needs. Mobile nodes in a
MANET communicate to each other without base station,
without the aid of any centralized administration hence
it is also known as an infrastructure less wireless
network. MANET employs its mobile nodes as a part of
the networking system. Each node in MANET can act as
an intermediate node, i.e. as a relay to forward packets
of data and do routing functionality. In MANET, mobile
nodes are free to move arbitrarily. It leads to an important
property of MANET which is dynamic topology.
MANET routing protocols can be classified into demanddriven
routing protocols and table-driven routing
protocols. Demand-driven protocols create routes only
when the source node initiates a route discovery process.
Examples of demand-driven protocols are Ad Hoc On-
Demand Distance Vector (AODV) and Dynamic Source
Routing (DSR). Table-driven protocols attempt to
maintain consistent, up to date routing information in
routing tables on every node. Examples of table-driven
protocols are Destination Sequenced Distance Vector
(DSDV) and Optimized Link State Routing (OLSR).
command.
CONCLUSION
In future Computer communication based telemedicine
will be implemented in rural area by very low cost for
live or store and forward method of transmission and
receiving. All the small scale Hospital can act as a TM
foundation in rural area. The Mobile also can be
implemented for TM node, some time it act as a TM
foundation if we connected Distributed Network sharing
through internet connection. The quality of transmission
is very high in digital [9][10]. Grid technology of
telemedicine network by sharing distributed by internet
and support complicated and complex connection of
telemedicine network.
