In this paper, a heuristic adaptive routing algorithm for an energy-efficient configuration management has been suggested which can reduce energy consumption while guaranteeing QoS for the emergency data in wireless body area networks (WBANs). The priority and vicinity of the nodes are taken into account for the selection of reachable parent nodes, when the(More)
—This letter presents a fast IP mobility management scheme in vehicular networks where multiple wireless network interfaces are used to perform the fast handover without packet loss. In order to do that, the IETF standard HMIPv6 has been extended, where multiple simultaneous tunnels between the HMIPv6 MAP and the mobile gateway are dynamically constructed.(More)
In this paper, we present an adaptive handover method with application-awareness for multimedia streaming service in wireless local area networks. Traditionally, the handover method in wireless local area network did not take into account the characteristics of the application service. Thus, the severe service disruption may occur during the movement of(More)
Most of the current mobility management protocols such as the mobile IPv4 or mobile IPv6 and its variants standardized by the IETF do not support global seamless handover. This is because they require comprehensive changes in the existing network infrastructure. In this article, we propose a simple mobility management protocol (SMMP) which can support(More)
Precise localization of Wi-Fi Access Point (AP) is becoming increasingly important with the rise of diverse location-based services based on smartphone. In this article, we propose a new method for precise Wi-Fi AP localization using GPS information of smartphone. The idea is that the possible area of Wi-Fi AP location, called AP_Area, is first determined(More)
Most of the current mobility management protocols such as Mobile IP and its variants standardized by the IETF may not be suitable to support mobility management for Web-based applications in an Internet of Things (IoT) environment. This is because the sensor nodes have limited power capacity, usually operating in sleep/wakeup mode in a constrained wireless(More)
In this article, we propose a P2P-based mobility management protocol for global seamless handover in heterogeneous wireless networks. Unlike previous mobility management protocols such as IETF MIPv4/6 and its variants, the proposed protocol can support global seamless handover without changing the existing network infrastructure. The idea of the proposed(More)
