Communication privacy techniques that protect the locations of source sensor nodes and sink nodes from either global or local adversaries have received significant attention recently. The improvement in capture time, which is the time it takes for an adversary to identify the location of the source, is often estimated using simulations. In this paper, we present probabilistic models to analyze ...

Packet forwarding on the Internet is solely based on the destination address of packets, and it is easy to forge the source address of IP packets without affecting the delivery of the packets. To solve this problem, one can have routers check whether or not every packet comes from a correct direction based on its source address field. However, due to routing asymmetry in today’s Internet, a rou...

Wireless ad-hoc networks are characterized by the lack of infrastructure, use of wireless links with limited bandwidth and frequent topological changes. On-demand multipath routing in wireless ad-hoc networks is effective in providing resilience to route failures and to successful load balancing. Previous work shows that on-demand multipath routing protocols achieve lower end-to-end delay, rout...

Efficient routing algorithms are now becoming more and more necessary for productive Massively Parallel Processing (MPP) Computers, such as the Red Storm Supercomputer located at Sandia National Laboratories, NM. Some current implementations of MPP computers have used source-based routing, which during nodal failures, requires the entire network to halt and recompute routing tables. It should b...

An extremely reliable source to sink communication is required for most of the contemporary WSN applications especially pertaining to military, healthcare and disaster-recovery. However, due to their intrinsic energy, bandwidth and computational constraints, Wireless Sensor Networks (WSNs) encounter several challenges in reliable source to sink communication. In this paper, we present a novel r...

Ad hoc wireless multi-hop networks (AHWMNs) are communication networks that consist of wireless nodes, placed together in an ad hoc manner, i.e. with minimal prior planning. All nodes in the network have routing capabilities and forward data packets for other nodes in multi-hop fashion. AHWMNs pose substantially different challenges to routing protocols than more traditional wired networks. AHW...

Mobile Ad hoc NETworks (MANETs), represent an emerging class of networks in which wireless mobile nodes operate independent of a backbone infrastructure. While hosts in traditional networks often rely on a designated router to forward data, every host in a MANET is required to route and forward data. The network hosts, such as laptops and personal digital assistants, operate on constrained batt...

Virtual-circuit switching achieves high forwarding performance via the combination of a hardware frame forwarding path and link-layer connection state that is stored in each switch along a virtual circuit. A similar result can be achieved when forwarding datagrams across an internetwork by uncoupling forwarding from hop-by-hop routing. That uncoupling is achieved by using a specialized network-...

--In this we address the dynamical jamming problem in wireless mesh networks and although some research has been conducted on countering Jamming attacks. Generally Multipath source routing protocols allow a data source node to distribute the total traffic among available paths. We consider the problem of jamming-aware source routing in which the source node performs traffic allocation based on ...

Sink location is considered as a basic service in geographic routing in wireless sensor networks. Obtaining the location of sink node by source node using an efficient method with low complexity has always been a challenging issue in research. In this paper, a sink location algorithm based on Fano plane is proposed. The research challenge is how to ensure the intersection of two SLQ (Location Q...
