| Abstract(in English) | In this paper, we propose a broadcast-based protocol for cache invalidation in location-aware system, wherein each client uses local caches of location dependent data to reduce network accesses. The proposed protocol is designed to avoid sleep fragmentation in clients and reduce waiting time for getting required invalidation information. To realize short waiting time, we use Bloom filter to express and compress invalidation information and shorten time for accesses to nearby invalidation information on broadcast schedule. Also we propose three broadcast scheduling methods: FASM (Fragmentation Avoidance Scheduling Method), MBSM (Metrics Balancing Scheduling Method), and MASM (Minimizing Access time Scheduling Method). The effectiveness of the proposed methods is evaluated by simulation. |
