Routing in frequency-hop packet radio networks with partial-band jamming
TLDR
It is found that LRR is an effective way for dealing with mobile jamming in a frequency-hop packet radio network and significant increases in throughput and end-to-end probability of success are obtained with LRR.Abstract:
Research in adaptive, decentralized routing for frequency-hop packet radio networks with mobile partial-band jamming. A routing technique called least-resistance routing (LRR) is developed, and various versions of this routing method are examined. LRR uses a quantitative assessment of the interference environment experienced by a radio's receiver to determine a resistance value for that radio. Two components for the interference environment are considered: transmissions from other radios and partial-band jamming. The resistances for each of the radios in a particular path are combined to form the path resistance, and packets are forwarded on the path with the smallest resistance. Comparisons are made between different versions of LRR and between LRR and previously developed adaptive routing techniques. It is found that LRR is an effective way for dealing with mobile jamming in a frequency-hop packet radio network. Significant increases in throughput and end-to-end probability of success are obtained with LRR. >read more

Securing ad hoc networks
Lidong Zhou,Zygmunt J. Haas +1 more
TL;DR: This article takes advantage of the inherent redundancy in ad hoc networks-multiple routes between nodes-to defend routing against denial-of-service attacks and uses replication and new cryptographic schemes to build a highly secure and highly available key management service, which terms the core of this security framework.

Ram Ramanathan,Martha Steenstrup +1 more
TL;DR: This paper describes three key components of the MMWN system: the clustering procedures for defining a virtual, hierarchical control structure superimposed on a large network of mobile switches and endpoints; the location management procedures for determining the current locations of mobile endpoints relative to the hierarchicalcontrol structure; and the virtual circuit management Procedures for setting up and repairing virtual circuits as switches andendpoints move.

Source-tree routing in wireless networks
TL;DR: Simulation results show that STAR is an order of magnitude more efficient than any topology-broadcast protocol, and four times moreefficient than ALP, which was the most efficient table-driven routing protocol based on partial link-state information reported to date.

Frequency-hop transmission for satellite packet switching and terrestrial packet radio networks
TL;DR: The performance of frequency-hop transmission in a packet communication network is analyzed and new measures of "local" performance are defined and evaluated for networks of this type, and new concepts that are important in the design of these networks are introduced.

TL;DR: The erasure of unreliable symbols improves the performance of most types of error-control coding if a good method is used to decide which symbols should be erased and error probabilities are reduced by several orders of magnitude.
