On Signature Caching of Wireless Broadcast and Filtering Services
Dik Lun Lee, Wangchien Lee · 1996
This paper discusses signature caching strategies to reduce power consumption for wireless broadcast and filtering services Four caching policies are compared in terms of tune-in time and access time With reasonable access time delay all of the caching policies help in reducing tune-in time for the two-level signature schemeMoreover two cache replacement policies are presented and compared by simulation The result shows that when the cache size is small caching only the integrated signatures is recommended When the size of cache is greater than that of the integrated signatures caching both of the integrated and simple signatures is better.
