A hybrid ad hoc network is a structure-based network that is extended using multi-hop communications. Indeed, in this kind of network, the existence of a communication link between the mobile station and the base station is not required: A mobile station t ...
Replacing or adding network protocols at runtime is problematic – it must involve synchronization of the protocol switch with ongoing local and network communication. We define a formal mathematical model of dynamic protocol update (DPU) and use it to defi ...
We consider the problem of correlated data gathering by a network with a sink node and a tree based communication structure, where the goal is to minimize the total trans- mission cost of transporting the information collected by the nodes, to the sink nod ...
This paper combines various self-stabilization techniques within a replication protocol that ensures eventual consistency in large-scale distributed systems subject to network partitions and asynchrony. A simulation study shows that the resulting protocol ...
As a component of the intelligent transportation system (ITS) and one of the concrete applications of mobile ad hoc networks, inter-vehicle communication (IVC) has attracted research attention from both the academia and industry of, notably, US, EU, and Ja ...
For a class of sensor networks, the task is to monitor an underlying
physical phenomenon over space and time through a
noisy observation process. The sensors can communicate back
to a data collector over a noisy channel. The key parameters
in such a se ...

This thesis is concerned with problems in decentralized communication in large networks. Namely, we address the problems of joint rate allocation and transmission of data sources measured at nodes, and of controlling the multiple access of sources to a sha ...
In this paper we consider the online ftp problem. The goal is to service a sequence of file transfer requests given bandwidth constraints of the underlying communication network. The main result of the paper is a technique that leads to algorithms that opt ...
When striving for reliability, multicast protocols are most commonly designed as deterministic solutions. Such an approach seems to make the reasoning about reliability guarantees (traditionally binary "all-or-nothing"- like) in the face of packet losses a ...
Traditionally, reliable multicast protocols are deterministic in nature. It is precisely this determinism which tends to become their limiting factor when aiming at reliability and scalability, particularly in highly dynamic networks, e.g., ad hoc networks ...
