ATM networks have many paths linking each host pair to achieve high bisection bandwidth for arbitrary communication patterns. Completely exploiting the bisection bandwidth may require flows between the same source and destination pair to take dissimilar paths to avoid hot spots. Though, the prevailing routing protocols have little support for load-sensitive adaptive routing [1]. This work proposes...
Resource allocation and scheduling are great challenge in grid environment. As the number of grid system component increases, the probability of a failure in the grid computing becomes higher. Users not only expect to commitment to perform a task in minimum time but also expect commitments to the level of Quality of Service (QoS). The aim of this paper is to utilize the resource to improve the throughput...
An ad hoc network is a collection of computers (nodes)that cooperate to forward packets for each other over a multihop wireless network. Users of such networks may wish to use demanding applications such as Voice over IP, videoconferencing, and streaming media when they are connected through an ad hoc network. Because over provisioning, a common technique in wired networks, is often impractical in...
Denial of Service (DoS) attacks constitutes one of the major threats and among the hardest security problems in today's Internet. Of particular concern are Distributed Denial of Service (DDoS) attacks, whose impact can be proportionally severe. With little or no advance warning, a DDoS attack can easily exhaust the computing and communication resources of its victim within a short period of time....
