We describe a priority based caching policy for a hybrid IoT proxy which is updated using POST methods from IoT nodes. However, if the user request finds that cached record is outdated, the proxy will send a validation GET request to the IoT node. We model the performance of the multi- staged IoT proxy/gateway, assuming two classes of user requests with different arrival rates. We investigate the effects of caching in maintaining the freshness of cache records while maintaining low delay and low energy communications. A network of queues is used to model the hybrid proxy IoT gateway over a single hop 6LowPAN/IEEE 802.15.4 cluster. The evaluation results show that the proposed model can reduce the probability of outdated records while providing energy saving for both classes of the requests.
