Movement prediction based cooperative caching for location dependent information service in mobile ad hoc networks |
Abstract | ||
|---|---|---|
Location Dependent Information Services (LDISs), through which mobile clients can access location sensitive data such as weather
information, traffic reports, and local news, are gaining increasing popularity in recent years. Due to limited client power
and intermittent connectivity, caching is an important approach to improve the performance of LDISs. In this paper, we propose
a cache replacement policy called Location Dependent Cooperative Caching (LDCC). Unlike existing location dependent cache
replacement policies, the LDCC strategy applies a prediction model to approximate client movement behavior and a probabilistic
transition model to analyze the communication cost. These models are used in the design of a cache replacement policy to improve
system overall performance. Simulation results demonstrate that the proposed strategy significantly outperforms existing caching
policies in providing LDIS in mobile ad hoc networks. |
