Abstract

This paper describes the function of handheld devices in mobile computing and the consequential security issues. The paper discusses the importance of a robust security policy to meet the challenges thrown up by penetration of handheld devices in business computing. This paper outlines some of these inherent challenges of mobile applications and puts forth the urge for a strong security policy to counter them. The paper starts with a broad scenario on mobile computing and then moves on two describe a few basic terms akin to mobile commerce. In this paper, the term handheld devices are used as a common name for all pocket-sized smart-phones and PDA (Personal Digital Assistant) devices using an open operating system. The central theme of this paper is that as Wireless/mobile devices and networking technology extends the traditional wired LAN, WAN, and even the Internet to include connectivity utilizing radio technology, the very nature of wireless technology presents unique security challenges. We converse security issues and their existing solutions in the mobile ad hoc network. be obligated to the defenseless of the mobile ad ad hoc network, there are abundant security intimidation that disturb the improvement of it. We first evaluate the main vulnerabilities in the mobile ad hoc networks,which have made it much easier to go through from attacks than the long-established wired network. Then we discuss the security criteria of the mobile ad hoc network and present the main attack types that exist in it. Finally we survey the existing security solutions for the mobile ad hoc network.
