Mobile ad hoc networks (MANETs) conveniently complement infrastructure-based networks, allowing mobile nodes to spontaneously form a network and share their services, including bridging with other networks, either infrastructure-based or ad hoc. However, distributed sensor provisioning over MANETs requires adequate support for service discovery and invocation, due to the network's dynamics and resource...
Recursive patching shares existing video streams recursively with asynchronous clients for efficient multicast in large-scale video-on-demand systems (VOD). In this paper, we propose Practical Patching that removes useless data included in transition streams of Recursive Patching. Practical Patching expands ongoing transition streams dynamically when a new request actually arrives at the server. We...
Mobile ad-hoc network (MANET) is a network of mobile nodes that do not have a fixed infrastructure. Recent research in this field addresses ways of solving existing problems in a MANET by using the node location information. However, maintaining the location information of the nodes is one of the essential challenges in mobile ad-hoc networks because the location of a node changes frequently. In this...
The rapid proliferation of wireless networks and mobile computing applications has changed the landscape of network security. Anomaly detection is a pattern recognition task whose goal is to report the occurrence of abnormal or unknown behavior in a given system being monitored. This paper presents a dynamic anomaly detection scheme that can effectively identify a group of especially harmful internal...

Recursive Patching recursively shares existing video streams with asynchronous clients for efficient multicast in large-scale video on demand systems. In this paper, we propose Practical Patching that removes unnecessary data included in transition streams of Recursive Patching.

Location services are used in mobile ad hoc and hybrid networks either to locate the geographic position of a given node in the network or for locating a data item. One of the main usages of position location services is in location based routing algorithms. In particular, geographic routing protocols can route messages more efficiently to their destinations based on the destination node's geographic...
