<b>A Cellular Bonding and Adaptive Load Balancing Based Multi-Sim Gateway for Mobile Ad Hoc and Sensor Networks</b>

<p dir="ltr">As it is well known, the QoS(quality of service) provided by mobile Internet access point devices is far from the QoS level offered by the common ADSL modem-router due to several reasons: in fact, mobile Internet access networks are not designed to support real-time data traffic because of several drawbacks concerning the wireless medium such as resource sharing, traffic congestion, radio link coverage etc., which impact directly such parameters as delay, jitter, and packet loss rate that are strictly connected to the quality of user experience. The main scope of the present paper is to introduce a dual USIM HSPA gateway for ad hoc and sensors networks thanks to which it will be possible to guarantee a QoS suitable for a series of network-centric application such as real-time communications and monitoring, video surveillance, real-time sensor networks, telemedicine, vehicular and mobile sensor networks and so on. The main idea is to exploit multiple radio access networks in order to enhance the available end-to-end bandwidth and the perceived quality of experience. The scope has been reached by combining multiple radio access with dynamic load balancing and the VPN (virtual private network) bond technique.</p>
