Cooperative Caching in IEEE802.15.4 based WSNs

摘要

Wireless sensor networks (WSNs) based on the IEEE 802.15.4 MAC and PHY standards are a recent trend in the market. Due to its low power consumption characteristics and low data rate, it gained a lot of attention. However, for large networks, spreading of overheads over the entire network is still a problem. The energy consumption can be reduced by minimizing overhead by combining new collaborative caching schemes and providing data with minimal latency, thereby reducing energy consumption. This article explores the possibility of improving energy efficiency by consolidating caching strategies.
