Optimal tradeoffs for location-based routing in large-scale ad hoc networks

Taejoon Park, K.G. Shin
2005 IEEE/ACM Transactions on Networking  
To find the optimal thresholds for the hybrid protocol, we derive the costs associated with both location updates and route discovery as a function of location-update thresholds, assuming a random mobility  ...  We first prove that the total cost is a convex function of the thresholds, and then derive the optimal thresholds.  ...  We then derive the total cost associated with both location updates and route discovery as a function of the location-update threshold.  ...

Noman Islam, Zubair A. Shaikh
2015 arXiv   pre-print
We have proposed a novel approach to Service Discovery in Mobile Ad hoc Networks.  ...  Fig 4a shows the simulated results with a network of 20 nodes with 10 services. The parameter we measured is the number of service discovery requests that are locally satisfied.  ...  QoS) specified by the user and constraints (e.g. cost) specified by the provider. Service Discovery in MANET is a very challenging task due to a number of issues.  ...

RADAR: Ring-Based Adaptive Discovery of Active Neighbour Routers [chapter]

Sylvain Martin, Guy Leduc
2002 Lecture Notes in Computer Science  
Such an automatic discovery is the key to administration of large or sparse active networks and the first step towards an efficient active routing.  ...  The RADAR protocol and its underlying neighbourhood discovery framework extend the ANTS toolkit by giving active nodes the ability to discover dynamically other active nodes close to them without relying  ...  If RADAR's threshold is properly set up, we can make the discovery daemon continue and find both X and Y . Capsules will now be routable directly from S to Y without extra cost.  ...

The application agents and web services based on ontology

WANG Yi, Huijuan SUN
2012 International Journal of Education and Management Engineering  
In this information-exploding era, the user expects to spend short time retrieving really useful information rather than spending plenty of time and ending up with lots of garbage information.  ...  Our contribution is an overall solution based on a fully-fledged architecture and proof-of-concept implementation that serves as a meeting point for both service consumers and service providers through  ...  Fig.2 shows our second test result and it demonstrates that unified discovery costs less time than service discovery.  ...

Uisce: Characteristic-based routing in mobile ad hoc networks

Guoxian Yang, Stefan Weber
2011 2011 The 10th IFIP Annual Mediterranean Ad Hoc Networking Workshop  
In wired networks, identities such as IP addresses are used to guide information through a network and the properties of network nodes are mapped to these identities by service discovery mechanisms.  ...  The goal of communication in computer networks is the delivery of information to endpoints with certain properties.  ...  In this paper, we select c(x) = λe x τ + a if x > threshold x, if x ≤ threshold (1) to describe the weight cost. τ ,λ and a are parameters to shape the cost function.  ...
