ABSTRACT
In mobile environments, as computers move to unknown networks, they need to discover new services, applications, and other network resources. Since the performance characteristics of such environments are often poor (due mainly to wireless communications and the restricted power of machines), mobile hosts require access to the nearest equivalent of some resource. On the other hand, services and applications located on the fixed part of the network may need to be aware of mobile host locations, in order to redirect messages, replies, references, files, displays, and so on. To achieve such resource discovery and mobile host tracking, a possible solution is to use a mechanism that supports remote object references --- Stub-Scion Pair Chains --- extended to allow host movement, disconnection and reconnection. Given this mechanism, we are able to install on both the fixed and mobile parts of the network some dedicated objects that allow the management of resource accesses and locations of mobile hosts, via tables and chains of references.

Neighborhood-Based Route Discovery Protocols for Mobile Ad Hoc Networks
Network-wide broadcasting is used extensively in mobile ad hoc networks for route discovery and for disseminating data throughout the network. Flooding is a common approach to performing network-wide broadcasting. Although it is a simple mechanism that ...
Improving Probabilistic Route Discovery in Mobile Ad Hoc Networks
LCN '07: Proceedings of the 32nd IEEE Conference on Local Computer NetworksConventional on-demand route discovery methods in Mobile Ad hoc Networks (MANET) employ blind flooding, where a mobile node blindly rebroadcasts received Route Request (RREQ) packets until a route to a particular destination is established. This can ...
An adaptive and scalable resource advertisement and discovery strategy for mobile ad hoc networks
GPC'06: Proceedings of the First international conference on Advances in Grid and Pervasive ComputingEffective resource advertisement and discovery (Ad/D) are particularly important in mobile ad hoc networks (MANETs), due to network dynamics and resource constraints of wireless nodes. In this paper, we propose an adaptive and scalable resource Ad/D ...
