Mobile agents travel through servers for perform their programs and fault tolerance is fundamental and important in their itinerary. In the paper, are considering and described existent methods of fault tolerance in mobile agents. Then the method is considered that which uses cooperating agents to fault tolerance and to detect server and agent failure,(More)
In Mobile agents systems, agents can perform their programs with traveling from the server to others and fault tolerance is important in their itinerary. In the paper, existent methods of fault tolerance in mobile agents are considering and described. Then the method is considered that which uses cooperating two agents to fault tolerance, to detect and to(More)
Sensor networks consist of a large number of sensor nodes performing distributed sensing and event detection. As sensor nodes are energy-constrained, energy-efficient routing is essential for increasing the lifetime of sensor networks. This paper proposes a new extended hierarchical routing protocol for clustered networks wherein sensor nodes and cluster(More)
