Usability constraints of grid in ad hoc networks

The rapid growth of devices that can be connected wirelessly and the high bandwidth communication capacity among these devices makes implementation of Grid services practical in an ad hoc network today. In this paper we have proposed a new layer called Ad Hoc Grid Layer (AHGL) which contains all necessary services to create a grid environment in ad hoc networks. This layer considers the unreliability and resource limited nature of nodes that are part of ad hoc network also. We have also simulated AHGL in NS-2 simulator, and from the gained results we show that the Grid implementation in ad-hoc networks is not always efficient to speed up the process of job execution. Based on this we have also defined some constraints to see when the Grid implementation in ad-hock networks is efficient to be used. This is done by considering the influence of network transmission time in job execution time.
