An ad-hoc wireless network is a collection of wireless mobile nodes that self-configure to construct a network without the need for any established infrastructure or backbone. Ad hoc networks use mobile nodes to enable communication outside wireless transmission range. With the advancement in wireless communications, more and more wireless networks appear, e.g., Mobile Ad Hoc NETwork (MANET), Wireless Sensor Network (WSN), etc. So, in this paper, the authors have discussed Ad Hoc Networks along with its energy issues, applications, QoS and challenges.
