Implementing a new system call in Kernel version 2.6.32

A system call is used by application or user programs to request service from the operating systems. Since the user programs does not have direct access to the kernel whereas the OS has the direct access. OS can access the hardware through system calls only. The following files has to be modified for implementing a system call /usr/src/linux-2.6.32.5/arch/x86/kernel/syscall_table_32.S /usr/src/linux-2.6.32.5/arch/x86/include/asm/unistd_32.h /usr/src/linux-2.6.32.5/include/linux/syscalls.h /usr/src/linux-2.6.32.5/Makefile New set of files to be created Create a new directory newcall/ inside the path “ /usr/src/linux-2.6.32.5/ ” Create new files Makefile, newcall.c and put them in the /usr/src/linux-2.6.32.5/newcall/ folder Create new user files (in any folder of Linux) to test the system call testnewcall.c, testnewcall.h (created in /home/pradeepkumar ) syscall_table_32.S Find the file /usr/src/linux-2.6.32.5/arch/x86/kernel/syscall_tab

Greedy Perimeter Stateless Routing (GPSR) protocol in ns3

GPSR - Greedy Perimeter and Stateless Routing. VANETs - Vehicular Adhoc NEtworks. PA GPSR, MM GPSR and GPSR. Under and post graduate - You can use the modules as it is and compare these protcols for VANETs. If you are a PhD scholar, you can modify the protocols and design your own GPSR alternatives. In this video, we will be seeing the installation of GPSR and some source codes. ns-3.27 which i could not succeed, So I prefer going to ns-3.23 we can both multiple version of ns3. I am going to run ns-3.23 for GPSR and other simulations with ns-3.27 and ns-3.29 Welcome to the Installation. If you are installing ns3 for the first time, install the following packages. (You can copy paste) $] sudo apt install build-essential autoconf automake libxmu-dev python-pygraphviz cvs mercurial bzr git cmake p7zip-full python-matplotlib python-tk python-dev python-kiwi python-gnome2 python-gnome2-dev qt4-dev-tools qt4-qmake qt4-qmake qt4-default gnuplot-x11 wireshark default-jdk We will
