Due to non inheritable restriction of sensors, there is always a vital issue on the way to utilize restricted energy effectively. In the proposed work we have focused on the Energy Consumption in WSN Using Mobile Sink and Hierarchal Clustering. There is concept of bringing mobile sinks to sensing field to save energy of cluster heads while sending data to mobile sinks instead of fixed sink on b...

Mobile agents are an increasingly popular paradigm and in recent years there has been a proliferation of mobile-agent systems. These systems are, however, largely incompatible with each other. In particular, agents cannot migrate to a host that runs a different mobile-agent system. Prior approaches to interoperability have tried to force agents to use a common API and so far none have succeeded...

An outstanding security problem in mobile agent systems is resource access control, or authorization in its broader sense. In this paper we present an authorization framework for mobile agents. The system takes as a base distributed RBAC policies allowing the discretionary delegation of authorizations. A solution is provided to assign authorizations to mobile agents in a safe manner. Mobile age...

Mobile technology offers an unprecedented growth opportunity for banking industry in Tanzania. As the economy continues to prosper, increasingly affluent consumers and underbanked segments create demand for new financial products and services. Many consumers in Tanzania have mobile phones, but not bank accounts. Therefore, the mobile channel presents an effective way to connect them to the nati...

The performance of smart grid applications such as advanced metering interest in the use of the forward error correction (FEC) codes Gilbert channel model. evaluation of routing protocols for mobile ad hoc networks,” Mobile. teria for performance evaluation. Time could also be used

The robot localization problem requires a mobile robot to determine its current location in an environment, given some initial information about the environment. We assume that the robot’s environment is represented by an occupancy grid. The grid is a rectangle of square cells, each of which is either obstructed or unobstructed. All the edge cells of the rectangle are obstructed. The robot can ...

In this paper we describe an algorithm for fault-tolerant sensor mapping for robotic vision. Basically, we use a certainty grid algorithm to map distance measurements into a two-dimensional grid. The well-known certainty grid algorithm can tolerate occasional transient sensor errors and crash failures, but will fail when a sensor provides permanently faulty measurements. Therefore we extended t...

The ETSI Technical Committee (TC) GRID is addressing issues associated with the convergence of IT and Telecommunications, with particular reference to the lack of interoperable Grid solutions. The integration of grid technology provides new revenue streams for Telecom operators through their converged fixed, mobile and data services from their Next Generation Network (NGN) and by offering “Grid...

The CoABS Grid integrates heterogeneous agent-based systems, object -based applications, and legacy systems. The CoABS Grid does not mandate the network protocol used to deliver messages to an agent or the agent communication language. A CoABS Grid agent registers a proxy object supporting a well-known message-delivery interface in a lookup service. Default proxy implementations are provided th...

Autonomous robots must be able to learn and maintain models of their environments. Research on mobile robot navigation has produced two major paradigms for mapping indoor environments: grid-based and topological. While grid-based methods produce accurate metric maps, their complexity often prohibits efficient planning and problem solving in large-scale indoor environments. Topological maps, on ...
