Networks are collection of two or more connected computers. People can share data as well as peripherals and also communicate through these networks. The networks are of 2 types: Wire-lined and Wireless networks. Most wired networks contain a hub or a switch to connect computers in the networks. Hubs forward data packets from one computer to another. In wireless networks Mobile Switching Centers acts like central hub. Hubs forward any data packet from one workstation to another. Examples of wireless networks include Cellular networks, Wireless Local Area Networks (WLAN), Wireless Personal Area Networks (WPAN), Wireless Sensor Networks (WSN), Internet of Things (IoT) etc. Compared to wired networks, Wireless or Ad hoc networks can be easily deployed anywhere for any applications including emergency scenario such as disaster management, remote healthcare monitoring, environmental monitoring, Mining, Space applications etc. There exist ongoing research issues and challenges to be faced upon using wireless networks in Routing, Mobility, Quality of Service (QoS), Security so on and so forth.
