Abstract: Over the last few years, the A?eld of wireless ad hoc networks has attracted tremendous interest from the research community. The ultimate goal of setting up a network is to exchange information. However, it is a challenging task to maintain data accessibility due to physical constraints of ad hoc networks.In this thesis, we propose some location-dependent data caching algorithms to increase data accessibility in mobile ad hoc networks. Location-dependent data handover and replacement schemes are proposed to maintain and further improve the performance of proposed caching schemes. Most of previous work used only Random Waypoint mobility model. In this thesis, Random Direction, Gauss Markov, Manhattan Grid and RPGM are also included. The impact of memory size, the request generating time, the maximum moving speed of mobile nodes on data accessibility is verified. The energy consumption is also examined.
