Due to the recent development of medical and wireless communication technology, the WBSN application is gradually increased to personal healthcare monitoring. WBSN is a network e where various kinds of bio signals of the body are measured and then are processed and transmitted to neighboring monitoring and personal portable devices. WBAN is a kind of network standard for supporting various connection...
In this paper, we address the issue of the joint detection schemes for uplink cellular system when base station cooperation is possible for multi-cell users in multi-cell scenario. The ML, MMSE and MMSE based SIC detection are analyzed and evaluated. ML attains the optimal performance but the complexity increases exponentially. MMSE is simple but has poor detection performance and SIC has better performance...
In the recent past we have been facing security challenges towards the transmission of biometric data over unsecured data channels. A lot of techniques have been developed and implemented for the secure transmission of the data. Taking the security concept in mind we introduce an efficient method based on chaotic theory for secured data transmission. The core idea of the proposed method is to shuffle...
Security of biometric data plays a major concern due to extensive use of biometric systems in many applications. This paper proposes an efficient method for encryption of iris images using edge based encryption algorithm based on chaotic theory. In this proposed technique, the iris image is segmented into significant and non significant blocks to find region of interest (ROI) i.e. to localize iris...
In this paper two stage biometric data protection scheme is being proposed using permutation and substitution mechanism of the chaotic theory which is lossless in nature. Arnold transformation and Henon map is used to design an efficient encryption system. The encryption method is aimed at generating an encrypted image that will have statistical properties completely dissimilar from the original image...
This paper proposes an IEEE 802.21 Media Independent Handover (MIH) functionality assisted Proxy Mobile IPv6 (PMIPv6) mechanism for reducing handover latency and signaling cost in heterogeneous wireless networks. The proposed mechanism comes to support fast vertical handover for the mobile node (MN) irrespective of the presence or absence of MIH functionality as well as IP mobility functionality....
This paper proposes a name system for Mobile-Oriented Future Internet (MOFI) that has been proposed to support the future Internet for mobile environment. The proposed name system for MOFI considers a host-centric for the current stage as well as an object-centric for the next stage. Firstly, a name space for objects is defined. To consider scalability and distributed architecture, the format of the...
In order that end-users in home networks can get opportunities for useful services beyond legacy Internet Protocol TV (IPTV) services, this paper proposes a service platform that resides on the residential gateway (RG) for interworking between home network and IPTV. The proposed service platform is called the home-oriented IPTV service platform (HISP) on the RG (HISP-RG). The proposed HISP-RG provides...
This paper proposes a measurement mechanism of IP performance metrics for network mobility (NEMO) in heterogeneous wireless networks. The key idea of the proposed mechanism is that mobile nodes (MNs) can get IP performance metrics irrespective of the presence or absence of measurement functionality. That is, the proposed mechanism does not require MNs to be involved in measuring IP performance metrics...
This paper proposes a new fixed-lag smoother for state estimation in discrete-time state space models, which is called the unbiased, fixed-lag, and optimal (UFO) smoother. The proposed UFO smoother is obtained by directly solving an optimization problem with the unbiasedness constraint using only the most recent finite observations. Therefore, the proposed UFO smoother is both unbiased and optimal...
This paper proposes a vertical handover mechanism for mobile devices to keep connection with the Internet in wired and wireless coexistence networks. To support vertical handover between two heterogeneous access networks, the intermediate driver including a virtual mini-port driver and a virtual protocol driver is developed newly. Then, an actual IP address is assigned to the virtual mini-port driver...
This paper proposes a new authorizing registration scheme for the Proxy Mobile IPv6 (PMIPv6) route optimization between the correspondent node (CN) and the mobile access gateway (MAG) on behalf of the mobile node (MN) in wireless access networks. Two scenarios are considered according to the type of CN. The tradeoff between security and QoS during the PMIPv6 route optimization procedure is briefly...
This paper proposes a new fast handoff scheme for Mobile IPv6 based wireless networks. To implement the proposed scheme, the beacon message used in L2 is defined newly by adding a specific subfield to the capability information field. In addition, Router Information Request/Reply messages used in L3 are defined newly. The proposed scheme provides the faster acquisition of new access router's network...
