Abstract

A mobile ad hoc network is a collection of wireless nodes that can be rapidly deployed as a multi- hop packet radio network without the aid of any existing network infrastructure or centralized administration. Therefore, the interconnections between nodes are capable of changing on continual and arbitrary basis. Nodes within each other's radio range communicate directly via wireless links, while those that are further apart use other nodes as relays. The primary challenge in building a MANET is equipping each device to continuously maintain the information required to properly route traffic. Key Words: Cellular network, adhoc network, mobile network security.
