CHALLENGES FACED AND POSSIBLE WAYS OF IMPROVING THEM. From what I have discovered, all the challenges for the network are subject to change. I will outline the challenges and discus how to solve them. A. Management 1) Challenge: It is said that increase of nodes might make it almost impossible to manage the network. There might security risks too involved. 2) Solution: In this world of ever changing technology, time has proven that anything is possible. Just a few centuries ago, we never thought we would fly, but now we not only can go around the world with Aeroplanes in hours but we can also go to the moon using a space shuttle. Time has proven to be an asset, hence, management of such a network needs just time for someone to come up with a new routing protocol. B. Costs 1) Challenge: The cost of managing the network would be expensive. 2) Solution: Time yet again plays a major role as a solution whereby, technology improves yearly and engineers find easier and cheaper ways of doing things for example a computers few years ago cellular phones were expensive but in this 21st century, cell phones are readily available to almost everyone. C. Health risk(radiation) 1) Challenge: High amount of radiation exposure is not good for the health. 2) Solution: It has been claimed that mesh clients and mesh routers produce a certain amount of radiation. The speculation about this fact hasnt been proven yet and is all based of probability and assumptions. There are two types of radiation: • ionizing radiation- dangerous • non-ionizing radiation- not dangerous The kind of radiation produced from the nodes fall under non￾ionizing radiation which is not dangerous. Furthermore, the fact that we have been having radiation caused by natural causes (like sun, underground gases, and soil) for millions of years and we havent been affected by it in the past, it means that non-ionizing radiation is not necessarily a threat as long as we control it. VII. CONCLUSION Wireless mesh networks is the key technology for the next generation wireless networking. It still growing but the fruits of it have proved to be promising and thus improvement of this network will have a huge impact in the next generation globalization.
