Human Health Aware Network Selection for Avoiding Health Disorders

Abstract

The primary objective of this paper is to minimize the health disorders caused by electromagnetic signals transmitted by the mobile devices. In literature, it is identified that the chance of getting health disorders such as depression, sleep disturbance, brain tumor, cancer, etc., is caused by the continuous exposure of radio signals from various sources like Mobile Base Stations, Mobile Devices and many other electrical or electronic devices. The impact of such EM radiation is based mostly on the SAR value which depends on the intensity and frequency of the radiation. The radiofrequency electromagnetic fields are grouped into “possible group 2B carcinogen” by the World Health Organization that has less proof of impact on human health, but the calculable SAR values are not too away from the safety standards. Today the usage of mobile devices with multiple network interfaces is quite common with every person in the urban areas than rural areas of India. Also, in urban areas, multiple base stations with different network standards are used to provide an overlapped coverage area which allows the mobile devices to select a best network among the available networks at any time. This paper proposes a new network selection scheme which considers various network parameters such as Cost of the Service, Security Level, Power Consumption, Network Status, and Available Bandwidth along with the SAR value for seamless mobility and to protect human health. To the best of our knowledge, this is the first handoff scheme which considers the SAR value as a handoff decision parameter. This proposed network selection algorithm will optimize the network performance and the SAR value to protect the human health.
