主  题:pervasive computing software update propagation mobile ad hoc networks 

摘      要:With the development of Internet technology,a large portion of computer softwares appear to run in a network-oriented,distributed-deployed,and self-evolving *** emerging wireless communication technologies broaden the usage of software in mobile platforms,enabling the pervasive computing paradigm,where people can access information/service anytime and anywhere with portable *** the pervasive networking environment where mobile devices operate on the ad hoc mode and communicate with each other opportunistically without wireless infrastructures,distributing the evolving software updates to a set of mobile terminals is a challenging *** this paper,we address the problem of distributing multiple software updates in pervasive networks with storage and bandwidth constraints,and propose age-based solutions to tackle this *** basic idea is to introduce different age-based priority mechanisms for propagation decision making in order to resolve the contention of wireless bandwidth and storage *** investigate a number of update propagation strategies including random spread,youngest age,and golden *** models are derived to analyse the performance of the proposed *** is shown that the golden age strategy has the burst effect,which could be used to enhance the efficiency of software update *** principles for choosing golden age values are proposed aiming to optimize different utility *** simulations under various network parameters show that the golden age strategy outperforms other strategies for multi-source software updates propagation.
