Problem in inserting a module into ubuntu kernel

Question

I am using Ubuntu-11.04 OS. i wrote a basic interactive kernel module mid.c

#include<linux/kernel.h>
#include<linux/module.h>
#include<linux/init.h>

static int __init insert(void)
{
  pr_info(" The module is inserted into the kernel \n");
  return 0;
}

static void __exit remove(void)
{
  pr_info("the module is removed from kernel \n");
}

module_init(insert);
module_exit(remove);

i can compile the module by using the command

make -C /lib/modules/2.6.38-8-generic/build M=$(PWD) modules

but when i try to insert the module using the command

insmod mod.ko

an error occurs saying :

cannot insert mod.ko permission denied

you need to add a sudo before insmod
