During the past few years, advances in mobile communication theory have enabled the development and deployment of different wireless technologies, complementary to each other. Hence, their integration can realize a unified wireless system that has the best features of the individual networks. Next-Generation Wireless Systems (NGWS) integrate different(More)
Virus diseases are among the key limiting factors that cause significant yield loss and continuously threaten crop production. Resistant cultivars coupled with pesticide application are commonly used to circumvent these threats. One of the limitations of the reliance on resistant cultivars is the inevitable breakdown of resistance due to the multitude of(More)
IEEE 802.11 based mobile communication towers is used very much in many personal and industrial purposes as it provides a continuous connectivity to Mobile Nodes (MNs) and allows them to change their attachment point from old Access Point (A)P to new AP while needed. But one main problem of continuous connectivity is handover latency which consists of(More)
Ginger, (Zingiber officinale Roscoe, Zingiberacae) is one of the important medicinal plant which naturally occurs in various country like India, China, South East Asia, West Indies, Mexico and other parts of the world. This natural gold has been consumed worldwide as a spice and flavoring agent from the ancient time. Ginger plants are generally 1-3 ft. in(More)
The critical infrastructures of a nation including the power grid and the communication network are highly interdependent. Recognizing the need for a deeper understanding of the interdependency in a multi-layered network, significant efforts have been made by the research community in the last few years to achieve this goal. Accordingly a number of models(More)
Next Generation Wireless Systems (NGWS) include co-existence of current wireless technologies such as WLANs, WiMAX, General Packet Radio Service (GPRS) and Universal Mobile Telecommunications System (UMTS). The important and challenging issue in NGWS is seamless handoff during the mobility of mobile node between different integrated networks. In this(More)
The power grid and the communication network are highly interdependent on each other for their well being. In recent times the research community has shown significant interest in modeling such interdependent networks and studying the impact of failures on these networks. Although a number of models have been proposed, many of them are simplistic in nature(More)
In low earth orbit(LEO) satellite network Mobility management is one of the key technologies. The aim of mobility management is to track where the subscribers are, allowing calls, SMS and other mobile phone services to be delivered to them. In this paper, we have proposed an idea of controlling the frequency hops and hence controlled the mobility management(More)
Wireless Sensor Network (WSN) consists of motes which are equipped with limited battery and requires energy management for enhanced Network Lifetime. In this paper we have adopted a deployment strategy which is performed over a region of interest (ROI) obtained from contour integration of one hop to other. The selection of motes depending on the type of(More)
