Internet of Things (IoT) is one of the most buzzing and discussed topic in research field today. Some of the researchers are also looking future of the world in this technology. Since then significant research and development have taken place on IoT, however various vulnerabilities are observed which shall keep IoT as a technology in danger. As a result, there are so many attacks on IoT have been...
The Vehicular Ad hoc Network (VANET) is the network of the mobile nodes which are connected without infrastructure. The mobile nodes requires routing that works with multi-hop characteristics. The clustering of node is needed in VANET. A cluster head is the essential part of any cluster for the efcient working of the cluster. In this work, we provide a method for the dynamically changing VANET, that...
Increase in average lifespan and aging population with increase in chronic diseases, there is need to monitor patient health status anywhere both in hospital and out of hospital. This demands more advance health care technology. Due to tremendous growth in sensor technology, the healthcare applications are increasing by manifolds. These opportunities have initiated many research proposals under healthcare...
A Wireless Body Area Network (WBAN) is considered as a special type of a Wireless Sensor Network (WSN) with its own challenges and requirements. A traditional WSN is designed to achieve higher efficiency, however, WBAN is designed to achieve maximum throughput, minimum delay and to maximize the energy efficiency, all together. Our analysis indicates that available protocols for WSN are not easily...
Universal Mobile Telecommunications System (UMTS), as a core network can support both circuit-switch as well as packet-switch networks. UMTS supports IP Multimedia services by including the IP Multimedia Subsystem (IMS) as part of its core network. IMS services are used by authenticating user equipment with the UMTS using UMTS AKA and then with the IMS using IMS AKA. This paper concentrates on the...
