Literature review
Nowadays, along with the development of the world, people now want to do much more complicated work. In order to handle these prolems, the systems of robot have een developed. Just like human, robots are always better when they work as a group, this is when the communication and coordination algorithms need to be applied. To have a better look about this systems, we need to understand clearly the term “ Swarm Robotics ” .
Defining swarm robotics
Şahin (2005, p.1) defined swarm robotics as a “novel approach to the coordination of large numbers of robots.” By simulating some properties of natural systems, this method is used to control a large number of similar robots to do complicated tasks that an individual robot cannot.
There are three properties that define swarm robotics and separate it from other multi-robot systems (Şahin, 2005). A swarm robotic system must be robust, which means that if any robot in the system stops functioning, the rest of the system still continues to …show more content…

However, due to large number of robots, and various environments that the group of robots may operate in, as well as changes in the number of robots in a group for different tasks, developing an effective algorithm for swarm robotics systems seems to be a great challenge. Stirling and Floreano (2010) proposed a system in which some robots act as communication relays, while other robots operate as normal troops. This method used no or low-bandwidth communication, and showed good scalability performance. However, the use of this methods is only limited to small area operation, as the range between communication relays and the robots are limited. Wireless LAN is a solution to this limitation, as it support long range as well as high-bandwidth communication, however this is proved to be a costly solution, as every robot in the system must have a WLAN module to support this method (Brambilla et al.,
