Performance evaluation of IP paging with power save mechanism

We evaluate the performance of IP paging with power save mechanism by formulating an analytical model and carrying out simulation study of integrated IP paging protocol (HPP) that integrates both the paging and power save functionality in IP layer. The results show that, compared to the mobile IP regional registration, the UPP significantly reduces the average power consumption of a mobile node and the signaling load in the access networks, while providing link layer independent mobility and power management functions.
