The central idea of this paper is to develop an algorithm that embeds the watermark information without much distortion to the Image , while making it possible to extract the watermark by use of correlation. We begin by modifying the frequency coefficients of the Image, based on human visual systems perception of Image content, which is used to embed a(More)
—The infrastructure of a Mobile Ad hoc Network (MANET) has no routers for routing, and all nodes must share the same routing protocol to assist each other when transmitting messages. However, almost all common routing protocols at present consider performance as first priority, and have little defense capability against the malicious nodes. Many researches(More)
Immunization saves millions of lives against vaccine-preventable diseases. Yet, 24 million children born every year do not receive proper immunization during their first year. UNICEF and WHO have emphasized the need to strengthen the immunization surveillance and monitoring in developing countries to reduce childhood deaths. In this regard, we present a(More)
We present a new software tool called CDN (Collaborative Data Network) for sharing and querying of clinical documents modeled using HL7 v3 standard (e.g., Clinical Document Architecture (CDA), Continuity of Care Document (CCD)). Similar to the caBIG initiative, CDN aims to foster innovations in cancer treatment and diagnosis through large-scale, sharing of(More)
The rising cost of healthcare is one of the major concerns faced by the nation. One way to lower healthcare costs and provide better quality care to patients is through the effective use of Information Technology (IT). Data sharing and collaboration and large-scale management of healthcare data have been identified as important IT challenges to advance the(More)

Since the structure is completely mobile, lack of central coordination, multi hop communications and limited resources provided by MANETs, QoS techniques need to be optimize the scare resource. A lot of research has been focused on providing QoS assurance in MANETs. The most important QoS metrics are packet delivery ratio, delay, through put and energy. It(More)
In wireless sensor networks energy is limited source. We must manage accurate use of energy for growing sensor lifetime. The hierarchy networks like Low-energy Adaptive Clustering Hierarchy (LEACH) choosing of cluster heads probability in some part of network haven't cluster head and other parts have cluster head with amount of density is high. Choosing of(More)
