The ability to discover services in Mobile Ad hoc Network (MANET) is a major prerequisite. Cluster basedcross layer intelligent service discovery for MANET (CBISD) is cluster based architecture, caching ofsemantic details of services and intelligent forwarding using network layer mechanisms. The cluster basedarchitecture using semantic knowledge provides scalability and accuracy. Also, the mini...

In a Peer-to-Peer (P2P) network, non-pipelining query result set delivery without a dynamic abort timeout feature is highly unreliable due to what we propose as the simultaneous abort problem: If only one of the many nodes in the query path fails to be responsive for whatever reasons, all other nodes in the chain are waiting, eventually time out at the same time, and the originator receives not...

Vehicular Ad-Hoc Networks (VANETs) is a novel technology that has recently emerged and due to its swift changing topology and high mobility nature, it has become problematic to design an efficient routing protocol in VANETs’ amongst both moving and stationary units. Also, the existing routing algorithms are not very effective to satisfy all requirements of VANETs. This paper explores the need o...

Web search engines are one of the most popular tools on the Internet which are widely-used by expert and novice users. Constructing an adequate query which represents the best specification of users’ information need to the search engine is an important concern of web users. Query expansion is a way to reduce this concern and increase user satisfaction. In this paper, a new method of query expa...

In this letter, we discuss a forwarding method for maximizing network lifetime, which combines multi-hop forwarding and direct forwarding with a direct/multi-hop forwarding ratio of each sensor node. The direct forwarding ratio refers to the forwarding amount ratio of sensor nodes’ own data directly towards a sink node in one packet/instance data generation rate. We tackle an optimization probl...

We investigate the problem of fast-forwarding quantum evolution, whereby dynamics certain systems can be simulated with gate complexity that is sublinear in evolution time. provide a definition considers model computation, Hamiltonians induce and properties initial states. Our accounts for any</mm...

Data link level forwarding provides simple and fast packet forwarding capability. One primary reason for the simplicity of layer 2 forwarding comes from its short, fixed length labels. A node forwarding at network layer must parse a relatively large header, and perform a longest-prefix match to determine a forwarding path. When a node performs layer 2 forwarding it can do direct index lookup in...

In this paper, we present a measurement study of persistent forwarding loops and a flooding attack that exploits persistent forwarding loops. Persistent forwarding loops may share one or more links with forwarding paths to some hosts. An attacker can exploit persistent forwarding loops to overload the shared links and disrupt Internet connectivity to those hosts. To understand the extent of thi...
