Network coding is an emerging technique known to improve the network performance in many aspects. In Vehicular Ad-hoc Networks (VANET), the bandwidth is considered to be one of the most important network resources. In this paper, we propose a network coding technique to improve the bandwidth utilization for non-safety applications in VANET. In a scenario where there are two sources broadcasting the...
IP mobility becomes more important with the emergence of various wireless communication technologies. Users move within the same wireless communication technologies or between different wireless communication technologies. Therefore, Internet Engineering Task Force (IETF) introduced Proxy Mobile IPv6 (PMIPv6) to cope with the IP mobility problem. PMIPv6 is a network-based mobility management where...
Seamless and fast handover is one of main goals in Long Term Evolution (LTE) in supporting mobility and maintaining user's quality of services. Mobility prediction is a technique to identify future targeted base station in advance, to reduce handover latency, and finally to enhance handover performance in wireless networks. In this paper, mobility prediction via Markov Chains with an input of user's...
The tremendous challenging in Wireless Sensor Network (WSN) straightly focuses on scalability of network and power consumption to guarantee the receiving of data. In Wireless Underground Sensor Network (WUSN), the proposed routing protocol not only considers the two issues above but also the different of communication medium and the reliable underground link. Based on those issues, the method and...
With the growing of telecommunication technology, people can connect to the Internet wirelessly anywhere and anytime. IEEE 802.11 Wireless Local Area Network (WLAN) became the preferred technology for providing Internet access in both indoors and outdoors environments for private and public usage. In order to establish the connection, users need to authenticate and associate with the Access Point...
Proxy Mobile IPv6 (PMIPv6) has been developed by the Internet Engineering Task Force (IETF) as a network-based mobility management protocol. The development is aimed to guarantee and support mobility for IP devices or Mobile Node (MN) without the MN involving in any IP layer mobility related to signaling. Using global mobility protocol, managing localized mobility has many problems, therefore PMIPv6...
