Opis:: In the paper authors continue the development of a model of dynamic power management in energy-aware computer networks, where two criteria: energy consumption and the quality of service are considered. This approach is appropriate when the routing problem with fixed demands is inadmissible. The formulation introducing edge indices is modified and tests on problems of different sizes are performed.

Opis:: There are advantages in considering the routing problem in integrated communication networks as a multiobjective shortest path problem, having in mind to grasp eventual conflicts and trade-offs among distinct objectives and quality of services (QoS) constraints. On the other hand the utilisation of dynamic routing methods in various types of networks is well known to have significant impact on network performance and cost, namely in overload and failure conditions. This paper presents the detailed formulation of a proposal of a multiple objective dynamic routing method (MODR) of periodic state dependent routing type, enabling to represent distinct QoS related metrics and requirements in a consistent manner. The MODR method present formulation is based on a multiple objective shortest path model with constraints and is prepared to use implied costs as one of the metrics. Alternative paths tor each traffic flow are changed as a function of periodic updates of certain QoS related parameters estimated from real time measurements on the routes and trunks of the network. Such paths are computed by a specialised and efficient variant of a bi-objective shortest path constrained algorithm, developed for the MODR, enabling to incorporate flexible requirements on the QoS metrics. The architecture of the routing system is discussed together with the features of its main modules. An illustrative example of application of the MODR path calculation module to a circuit-switched type network using blocking probability and implied cost as metrics, is also presented, considering different overload conditions.

Tytuł:: An identity-based broadcast encryption scheme for mobile ad hoc networks

Tematy:: dynamic mobile ad hoc network

Opis:: Dynamic ad hoc networks facilitate interconnections between mobile devices without the support of any network infrastructure. In this paper, we propose a secure identity-based ad hoc protocol for mobile devices to construct a group key for a setup of a secure communication network in an efficient way and support dynamic changing of network topology. Unlike group key management protocols proposed previously in the literature, mobile devices can use our protocol to construct the group key by observing the others' identity, like the MAC address, which distinguishes the device from the others. In contrast to other interactive protocols, we only need one broadcast to setup the group key and member removal is also highly efficient. Finally, we discuss the security issues and provide security proofs for our protocol.
