Paper Title
Mobile Ad Hoc Networks-An Overview
Abstract
Wireless networks use radio frequencies in air to transmit and receive data Wireless networks are formed of
routers which are responsible for forwarding packets in the network. A wired network relies on physical cables to transfer
data. The communication in a wireless network can be either wired or wireless. Wireless communication does not have the
constraint of physical cable. This is one of the advantages of a wireless network.Mobile Ad Hoc Network (MANET) is a
collection of wireless mobile nodes .Theyare characterized by multihop wireless connectivity, infrastructure less
environment and frequently changing topology. Since the network topologychanges frequently, efficient adaptive routing
protocols are used. As the network is wireless, security becomes the major issue in Mobile Adhoc Networks.The
transmission of data is disrupted due to behavior of malicious nodes which results in attacks such as modification,
fabrication, impersonation and denial of service attacks. This paper gives an overview of Mobile Ad Hoc Networks.
