Rendezvous and docking/berthing are key manoeuvers for various missions [1]. In those rendezvous phases where the accuracy of absolute navigation (e.g. by satellite navigation services like GPS or GLONASS) is no longer sufficient, sensors have to provide information about the relative position of active vehicle (chaser) and passive vehicle (target). Satellite navigation (differential GPS), radi...

A set of k mobile agents with distinct identifiers and located in nodes of an unknown anonymous connected network, have to meet at some node. We show that this gathering problem is no harder than its special case for k = 2, called the rendezvous problem, and design deterministic protocols solving the rendezvous problem with arbitrary startups in rings and in general networks. The measure of per...

Recently, wireless sensor networks (WSNs) have attracted attentions of many researchers since they can be used for wide range of applications such as environmental monitoring, security, disaster prevention, environmental control in office buildings, and precision agriculture. Control mechanisms for WSNs should adapt to a variety of communication patterns which reflect application requirements a...

Considerable interspecific diversity exists among bees in the rendezvous sites where males search for females and in the behaviours employed by males in their efforts to secure matings. I present an evolutionary framework in which to interpret this variation, and highlight the importance for the framework of (i) the distribution of receptive (typically immediate post-emergence) females, which o...

This paper proposes a rendezvous protocol for cognitive radio ad hoc networks, RAC2E-gQS, which utilizes (1) the asynchronous and randomness properties of the RAC2E protocol, and (2) channel mapping protocol, based on a grid Quorum System (gQS), and taking into account channel heterogeneity and asymmetric channel views. We show that the combination of the RAC2E protocol with the grid-quorum bas...

The space robot is the indispensable tool for future space activities such as building and operation of the international space station, inspection and repair of orbiting satellites, and conducting lunar/planetary explorations. The rendezvous docking technology to meet and to connect two spacecraft in-orbit is also an essential technology for the future space missions such as logistic support o...

In the future, embedded wireless networking will be included in many common, everyday objects. It is expected that this added functionality will enable an enormous variety of applications and services which have yet to be achieved or envisioned. Possible examples include sensor systems, smart toys and games, smart appliances, electronic access control, and a myriad of other in-home, business, a...

The ability to accurately classify network traffic and to perform timely detection of the presence of unwanted classes of traffic has important implications for network operations and security. In recent years, classification has become more challenging due to applications that use ports that are not wellknown, that overload or masquerade with other applications’ well-known ports, and that may ...

In the symmetric rendezvous search game played on Kn (the completely connected graph on n vertices) two players are initially placed at two distinct vertices (called locations). The game is played in discrete steps and at each step each player can either stay where he is or move to a different location. The players share no common labelling of the locations. They wish to minimize the expected n...
