Human health and velocity aware network selection scheme for WLAN/WiMAX integrated networks with QoS

Abstract

The objective of this paper is to propose a human health aware network selection scheme for integrated WLAN and WiMAX networks by considering the velocity of the mobile device, achievable SAR value, network condition and required bandwidth. This paper investigates the handoff-related issues in WLAN/WiMAX integrated overlay network, proposed handoff algorithms for two different scenarios, and evaluated the performance of the proposed scheme with respect to both fixed and mobile devices. Also, our handoff algorithm considers the parameters like bandwidth requirement, available bandwidth, the speed of the mobile terminal, and SAR value at the time of selecting the target point of attachment. This SAR based handoff helps the mobile users in saving battery power and in reducing the biological effects such as sleep disturbance, brain tumor, depression and cancer caused by EM signals on the human body. Thus our proposed handoff scheme improves the QoS and it protects the human health.
