Next generation wireless networks are envisaged to be an integration of different wireless networks and demand the ability of users to move from one network domain to another network domain seamlessly. Also these networks require superior handover techniques to provide ubiquitous access to roaming users with maximum network resource utilization. In order to(More)
In most of the wireless networks, signal strength is considered as the basic criteria to initiate handover. In future generation heterogeneous wireless systems, the vertical handover between different types of networks take place to satisfy demands of users. The location and velocity of mobile terminal is expected to be available in most of the modern(More)
Heterogeneous wireless networks are envisaged to be an integration of different wireless networks and demand the ability of users to move from one network domain to another network domain seamlessly. These networks are overlapped by each other to some extent. An appropriate time to initiate Handover (HO) is required to be calculated based on the necessity(More)
The rapid expansion of mobile communications over the last few years allows the users to communicate without geographical coverage limitations of individual communication systems such as WLAN and WiMAX. In order to achieve interworking of Internet with wireless networks and to meet the requirement of seamless HO for real time and multimedia applications,(More)
Availability of information has a key importance. Due to lack of in time information, the societal problems arises like disaster i. e. drought. Authors found that redressing of drought becomes more complex and rigorous. Survey shows that present computations does not support for public based sharing of the information to support and assist the community in(More)
For efficient and very high capacity network for Telecommunication and Data services the SONET/SDH network is used. The Service providers are keenly interested to find automatic ways of commissioning the channels associated with the SONET/SDH. The TDMA technology is used in the SONET/SDH network by which the High speed data communication and(More)
