State of Development


Over the past few weeks

the development

was

focused

mainly on
the
implementation

of the

web
monitoring

and configuration

interface

and improving

the
performance

in

the
Java

application
.
The main

difficulty in creating

the web

interface

was
the
communication

between the

Java application

and the

REST interface
.
SIM
cards

do not

allow

the company

to connect to

online servers

which
after

and

it

was

necessary to

find

other

compatible cards
.
After the

acquisition

development

has
focused on

adaptation of the

Java application to

communicate with the

online server

and the development of

the
REST interface
.
Then, it was

designed and

created

a
database

to store

the

information from the

modems.

It was also

necessary to create

a custom p
rotocol

to

manage
the
communication

to achieve better

efficiency

(the
justification for the
choice

of
developing a

custom protocol

with

REST

instead of

SOAP

is detailed in the
dissertation
).
After the information

being stored

in the database

it
is required

an

interface

to handle

this information
.
This interface is
being developed and can be
consulted in the link
http://paginas.fe.up.pt/~ee07231/modemEDP/Project/index.php
.
Currently
it can be seen the modems and SIM cards lsit along with their respective
parameters.

In addition to the

web interface

it
was also

implemented

several

techniques to
improve

the
performance

of

the modem’s
Java application
.
This is important

due to

the
Frontend’s

parameters
;
if the delay is

too large the
Frontend
’s timeout will drop
every frame therefore it is

important
to minimize the
processing delay
.
It was also

made

several tests

to check

the network speed

and

the impact of the
performance

implemented
.
For

each test

a
statistical

analysis was carried out

to
check whether

in fact

there was

a statistically significant improvement
.

Finally part of the work has been focused in writing the dissertation and
documenting the results
. The work over the next few weeks will be focused on the
further development of the web interface, dissertation writing and
continue the

performance improvement
