“…The handover itself is assumed to last T Handover = 250 ms [7], while its impact on the terminal energy is equivalent to a T Switch = 25 ms transmission phase at 1 W (we use a smaller value than T Handover as most of the handover duration consists only in waiting time; 25 ms at 1 W is likely to cover already more than the actual handover energy). An actual terminal could replace those values based on monitoring the true process.…”

This paper optimizes handover decisions between WLAN (802.11) and WiMAX (802.16e) standards, for both uplink and downlink data transmission. The handover becomes part of a cross-layer approach controlling several knobs (air interface parameters or platform settings) in order to reduce the terminal power consumption.The first step is to derive detailed power and performance models for both standards, in order to correctly evaluate the opportunity of a handover. This includes channel fading fluctuations, extraction of MAC-level behavior and packet error rates, and overall power consumption from the wireless platform. Such models enable first optimal single-standard power-throughput trade-offs, that will be used as reference points before adding the handover possibility in order to assess its specific gain.The second step is the design of a handover controller that selects the network with the lowest expected power for the required rate. The proposed mechanism is based on regular scanning of both networks. It computes the expected energy in order to send a given amount of data over each network, taking handover cost into account, and selects the most appropriate one.Based on a software-defined radio platform and a typical channel coherence time of one second, simulations demonstrate a power saving factor up to 2.5 as a function of the scenario, compared to a single-standard system that is already cross-layer optimized. This illustrates the large gain that is available, besides the handover advantage in terms of improved connectivity.

“…The MIIS will be used by the MME, an upper layer entity which implements network selection handover algorithms. The MME in our scenario initially uses DHCP [8] to acquire the location of IS, Specifically, the IS server's IP address, the IS server's FDQN (Fully Qualified Domain Name) and URI (Uniform Resource Identifier).…”

The emerging IEEE802.21 standard defines Media Independent Handover Functions (MIHF) that assist mobile nodes to seamlessly roam across heterogeneous access networks. The aim of this paper is to present a mechanism which uses existing IEEE802.21 MIH services to optimize the Fast Handovers for Mobile IPv6 (FMIPv6) procedure. For this, we have exploited the 802.21 Information services in particular to tackle issues such as radio access discovery and candidate access router discovery which are critical to the handover performance of FMIPv6. We will show through analysis that, when our proposed mechanism is applied, it increases the probability of predictive mode of operation by reducing the anticipation time and thereby reduces the overall expected handover latency in FMIPv6.

Abstract-The availability of multiple technologies, with micro and macro wireless cells, for network access combined with terminals capable of exploiting such diversity in wireless access requires the development of new mechanisms for optimized handover procedures. Appealing solutions should support network controlled handovers through heterogeneous technologies, preferably combined with a cross-layers two/three design. The IEEE 802.21 working group is currently standardizing the methods and the protocol potentially able to provide such a solution. In this paper we analyze the impact of signaling timing on network controlled handovers execution and performance in this environment. Through an extensive simulation study, we obtain results, that can be exploited in both terminal and handover procedure designs.
