I found the answer by myself. Maven selenium plugin just start the hub and not the selenium node (both integrated and standalone). In my case, it is old version of selenium 0.9 and unit testing uses DefaultSelenium so it require a node also which process browser commands by opening browser and console. So i started the hub and node using maven antrun plugin to start the server and hub like

<plugin>
    <groupId>org.apache.maven.plugins</groupId>
    <artifactId>maven-antrun-plugin</artifactId>
    <version>1.7</version>
    <executions>
    <execution>
        <phase>pre-integration-test</phase> 
        <configuration>
            <target>
                <property name="selenium.server.dir" value="${basedir}" />
                <path id="selenium.classpath">
                    <fileset dir="${selenium.server.dir}">
                        <include name="selenium*.jar" />
                    </fileset>
                </path>     
                <java classname="org.openqa.grid.selenium.GridLauncher"
                      classpathref="selenium.classpath"
                      failonerror="true"
                      fork="false">
                    <arg line="-role hub"/>
                </java>
                <java classname="org.openqa.grid.selenium.GridLauncher"
                      classpathref="selenium.classpath"
                      failonerror="true"
                      fork="false">
                    <arg line="-role node
                               -hub http://localhost:4444/grid/register"/>
                </java>
            </target>
        </configuration>
        <goals>
            <goal>run</goal>
        </goals>
    </execution>
    </executions>
</plugin>

It works now perfectly.
