Mobile Computing with WirelessLAN and its Modes Ad hoc Network with Challenges?

In this paper, we summarized Mobile computing with WirelessLAN and its modes Ad hoc network and infrastructure. We define the operational model of our mobile computing environment, where we plan to demonstrate our proposed solutions. Mobile cloud computing is the combination of both cloud computing and mobile networks to bring benefits for mobile users, network operators, as well as cloud computing providers. In the present mobile communication environment, lot of research is going on, to improve the performance of issues like handoffs, routing etc. Security is another key issue that needs to be considered, when the setup of communication channel is to be set. Wireless local area network (WLAN) security are inherently weak and do not provide adequate security. Newer, more robust, wireless security technologies are being developed but have not had widespread acceptance within corporate information infrastructures. An ad hoc network is a collection of mobile nodes equipped with wireless communication adapters; these nodes dynamically form a temporary network without the need of any existing network infrastructure. Earlier studies on ad hoc networks aimed to propose solutions to some fundamental problems, such as routing, coping with the new challenges caused by network's and nodes' features without taking the security issues into account.
