INTRODUCTION A network is collection of devices which are connected to each other for data exchange. Devices are linked with each other in order to share resources, exchange files or allow electronic communications. These are interconnected for sharing data quickly and easily. A network can be divided into wired and wireless networks. In wireless networks, there is no physical connection between devices or computers as there are some sort of radio frequencies in air to transmit and receive data instead of using physical cables. In wireless networks, cables are used at backbone and the computers are integrated with access points. Wireless networks work as same way as wired LAN using same protocols and applications. Wireless technology has made easier the sharing of resources in a home or business simultaneously by multiple computer users without exhibiting any additional or intrusive wiring. Wireless networks are easy to expand and inexpensive as compared to wired networks. The advantage of wireless networks is that it data can be shared globally at all parts of the world. Wireless networks are flexible and so it is ideal for non-reachable paces such as cross-river and mountains. The main disadvantage of wireless …show more content…

when there is a need to transmit data from source to destination a route discovery process is initiated by the source. In this process, the network is flooded with route request packets to create a suitable route from source to destination. The Routing table is also created on demand. Flooding is a reliable method of passing information to all the nodes present in the network; however it uses bandwidth and cause delays in packet transmission but decreases the control traffic overhead. After getting the best route, route establishment phase ceases with initiation of route maintenance phase which keeps up valid routes and remove all the invalid routes thus reducing
