Due to recent advances in mobile computing and communication technologies, mobile ad hoc computational Grids(MG) are emerging as a new computing paradigm, enabling innovative applications through sharing of computing resources among mobile devices without any pre-existing network infrastructure. MG extends the traditional Grid computing paradigm to include a diverse collection of mobile devices enabled to communicate using radio frequency, infrared, optical and other wireless mechanisms. The devices coming into use in MG implementations are tiny sensors, wearable computing devices, miniature mobile robotic systems, Radio Frequency Identification tags (RFID), Personal Digital Assistants (PDAs) and paging devices, smartphones, tablets, hand-held computers, laptop computers and special purpose computers embedded into many modern appliances. Though many of these devices were initially developed to serve a specific, autonomous purpose, their potential for cooperation through the sharing of resources and capabilities, and the massive amounts of resources available due to their numbers, is quickly leading to applications resembling traditional Grid computing. This paper presents a survey of the current state of MG. It discusses the current research of resource allocation in MG and the potential challenges resulting from the unique characteristics of wireless grid devices.Keywords

Real-time web applications have a time constraint. Such applications(server) may have mobile users(clients). A wireless mobile user may voluntarily disconnect itself from the Web server to save its battery life and avoid high communication prices. To allow Web pages to be updated while the mobile user is disconnected from the Web server, updates can be staged in the mobile host and propagated back to the Web server upon reconnection. Here we design algorithms for supporting disconnected write operations for wireless Web access and identify the optimal length of the disconnection period under which the cost of update propagation is minimized. The result is applied to real-time Web applications such that the mobile user can determine the longest disconnection period and propagate updates to the server before the deadline so that a minimum communication cost is incurred.
